Awesome, I may have to try this. With my sled I am limited in the width of the stock I can cut up into segments, your solution solves this problem. I really like how this sled concept is evolving.
BRAVO Jeremy. Through no fault of the original inventer of the wedgie sled he, like so many other inventers, are so in tuned into what they are creating that at times they can't see the more simpler way of going about it. Then young minds like yourself come along and see the easier way right off the bat of accomplishing the same task without all the added or needed complexities. What you have just shown here seems not only workable but also very practical but as you said not being one who has spent many hours of working with this type of woodwork project you might be missing something, BUT, I don't think so. Good work Jeremy and your presentation was also very well done. I really enjoy watching you at work. Keep it up.
I have to agree 100%. I have been teaching woodworking in high school for 25 years and I'm always looking for great lessons. You put this together in a perfect way. Easy to understand. Concise. Loved it! I will be a subscriber for sure.
Great idea with the cnc. I made a sled based on the original plans and created wedges out of acrylic using a laser engraver. I really like your idea of using the wedge as the fence, because it also means that the front and back edge are always equally aligned to the edge, unlike the original plan.
A key reason for the 2 fence design is to have your stock supported with both cuts. I will use a 1/8” backboard sometimes which reduces tearout and having support is key in getting perfect cuts. There are other reasons for the 2 fence design but support is a main one.
I keep seeing comments about tear out on the closest side of the wedge cuts. I'm thinking that an additional T-track on the left side of the sled (as you're looking down on it) with a sacrificial board bolted to it behind the wood being cut using the T-tracks would solve that problem. I plan on building this sled this week. If I find tear out to be an issue, I'll try the fix. Either way, this is an awesome idea, thanks for getting it out there!!!
Excellent thinking! Of course you get caught in the 'Catch 22' of having to cut a very precise pattern in order to be able to cut very precise pieces. At least you only have to do it once (not counting the six tries lol!) The advantage to the two fence system is that you can go to the nearest art supply store and buy 45 and 30/60 triangles to use for set ups. As Frank H. commented, this system does have the advantage of not restricting the width of the stiock (within reason). Thanks for the video! Keep making sawdust!
Of all the variations op0f the wedgy sled design I have seen, his one, by far, is the one I like most. I will probably end up redoing my segmenting sled after the current projects I am working on to help make mine much more accurate. Currently, I have to do things with the half ring method of gluing half the ring together, sand the joints between the 2 ring halves and then glue the whole ring together. Thanks for sharing such useful info!
+AnkleBiter Woodworks Thanks! I used to use the half ring method (that's how I made the bowl seen at the first of this video), but I always had to do it by hand because I didn't have any other way of straightening the mating faces... Thus this idea was born.
You young man are a credit to your trade you have a very well lit up workshop and your jigs superb A am a very old carpenter but i love the way you explain things so simply The best of Irish luck to you and keep the videos coming
Brilliant! So obvious, yet you're the first to my knowledge to build a better mousetrap. I was going to build the more traditional designed sled next week when I came across your video. Of course, you need to have a CNC to make this easy, and fortunately I do! Thanks for the great video. Keep em coming.
At the risk of sounding like a nerd... math is the way to go for setting out the accurate angles (as opposed to protractor tools) for exacting projects like segmented bowls etc. I really like your presentations. Many thanx.
Thank you very much for the clear explanation. Now I do not need to buy wedgies and can make them myself . You have always excellent ideas . You are always honest and are not aiming to sell any thing🌹
Hmm, could you give me an example of one person that is "do it like this and like that"? Because I can't think of anyone and you even claim it is everyone.
Neat! I bought several of the "wedgies" to set the segment angles. I can use them instead of cutting ones like you did. I think this is a brilliant design change.
Jeremy, I bought them from the SegEasy web site. The link to the sets and individual wedgies is: www.segeasy.com/toystore2.htm. They are made of a high density polyurethane and quite durable.
Using the wedgie as the fence is just brilliant. Plus solving the problem of stock width restriction. The answer was right there in our hands and no one saw it until now. Will some enterprising CNC owner please make the wedgies from a durable material for sale in a number of angles.
Looks like you should be able to do away with the sled and attach a slider directly to a wedge. You only have one slider anyway and your wood can move on the metal surface of the table saw this eliminating concern of overhang support for the 45 degree wedges. You would need to do away with the clamps which you probably won't need.
You are the first to suggest this! That's an interesting idea, and I think I'm gonna try it. Love the simplicity; no moving parts. I'm a bit worried that it could be harder to keep the stock against the fence, since it won't have the friction of the base to help hold it in place. But I'll try it and see how well it works. Thanks!
Jeremy Schmidt - I can think of a few ways to give you little more control but it's a little hard to describe. One idea would be to make the wedge maybe twice as wide while keeping your necessary side angles. This will allow for a longer slider to be attached to the bottom of the wedge and more surface area contact and weight of both items against the table saw metal surface. This should improve stability and allow you to concentrate on holding the stock piece better rather than juggling both the stock and the wedge. Next, you can cut some holes or long rounded edge slits that go parallel to the angle sides. These can give you the ability to stick your thumbs in the holes while half your palm and other fingers can serve to hold on to the stock piece more firmy against the wedge as you slide both pieces to do your cuts. Alternately, you can attach a 1" high block of wood flush with the angle sides of the wedge. This might be a little more comfortable to anchor your thumb(s) and hold the stock piece against the wedge. Also, if you design it to be removable, then you can use taller blocks for taller sock pieces. You can even remove them all together and rely on the "thumb holes" I mentioned earlier for when you are cutting thin pieces of plywood since you don't need to grip them as strongly as you would a bigger stock piece. Finally, flush strip attached to the wedge along the edges near the blade would be good for safety. This will help keep your hands and fingers from slipping off to the side and meeting the spinning blade. You can make that block even higher than the blade's highest setting. Your only using the angled edges for your cuts anyway, so that tall block along the side provides a good fence between your hands and the blade. It doesn't need to be too thick either. Half inch plywood with screws should work fine. I hope this helps. Good luck.
I love this. So simple and easy to use. Suggestion: Either steel sleeve in bolt holes or spline locater to keep accurate over long term use. The threads on the bolts will enlarge the plywood holes over time IMO. Hope this helps. Thanks
Thanks! If the wedges needed to be positioned accurately then sleeves would be a good idea. But that’s the beauty of having the front & back fence in one piece: the angle of the wedge relative to the sled doesn’t matter, only the angle of the two fences *relative to each other*, and that angle is immovable.
The reason the others have two fences compared to your one is in segmented work you can alter the fence angle of the two fences still using the wedge but the effect you get is a spiral rather than each angle pointing towards the center of the ring. You cant get the spiral effect with your setup, But still a good alternative. :-)
Thanks for the video. If you don't mind it's registered to the other face of the stock when you do the second cut, you might as well just flip the stock bottom-up and use the same face of the template/fence. That way the sled can be more compact as you don't need stock support room on both sides. You might even fit a 45 degree one or higher on bolts located top or bottom, whichever you prefer in controlling the stock and sled. It will only work with stock you can actually flip ofcourse, but I think the majority is?
+Dave Smulders You missed the point of the wedgie sled. What matters is that you cut one side of the joint on one side of the wedge, and the other side of the joint on the other side of the wedge. Because of this system there is absolutely no calibration to do; once you have the wedge on the right angle you can just slap it on the sled and make your cuts. Your idea is essentially the same as a miter gauge.
Yup I did :) Then the 45 degree one isn't all that bad either. If it's on just a bit crooked, the parts will still match, and although the lines won't be exactly crossing in the center it's only really marginal.
This is a much better solution if you have a zero clearance base plate. Single guide rail reference is just much easier to set up and be consistent with.
The only issue I see is not having the fence behind the blade as you mentioned in the video; however, I think one could fix the issue by putting one of Marius Hornberger's Cam clamps into the T-Track and tightening it down to the track. Then one could safely and quickly hold the stock against the fence. You said you were comfortable holding so may not be a solution you need.
Great video as usual, Jeremy, I love how you explain things. Now, about that bowl at the beginning... Are we going to see a video on that? I like the design.
+Johnny West Thanks! I made that bowl quite a while ago, and I posted about it on my Instagram at the time. So you can go dig through my Instagram archives and see a little more about it.
I just ordered a wedgie from the originator. And I was thinking of just attaching it to my sled. I thought I was on to something so I came to RUclips to see if someone beat me to it. Yup. Good job
ABSOLUTELY BRILLIANT!! Some of the earlier comments are great. The simpler sled is also more flexible and adaptable - with some added design features, it could become the only sled you will need!!.
Nice job. I think to reverse the bolts you could sink large all thread nuts in the base then cut them flush with the top Then you could use the bolts to hold it down
Hi Jeremy Your comment about mitre gauge accuracy I would challenge. As the old adage states you get what you pay for and if you buy a low cost mitre gauge it will more than likely not be accurate but if you buy one from INCRA out of Dallas you can get an accurate one for reasonable money and for a little more you can get even more accuracy. That is why they sell one hell of a load of them. Your wedgie sled has some benefits and I shall make one because my saw table does not have a standard mitre slot 3/4" by 3/8", but that is because in Europe folks like Festool set their own standards. Cheers
+Bawdsey64 You're right, a better miter gauge would be a different story. I have three of the style I showed and they are all junk, but they are all cheap ones. However, I am quite sure there is no miter gauge accurate enough to make a perfect 12-segment ring. As I said in the video, a half thousandth angle on the fence is unacceptable.
There is at least one huge disadvantage. With the wedgie sled you can scew the prices to the blade, so they aren't 90°. Doing that will give you almost the same pieces but when they glue up you'll see they spiral away from the center. You can make awesome patterns. You can still do that with your sled if you remove one pivot point.
Great video. Might have to rebuild my sled now. You also blew my mind with having the two heads on the combination square at once. Not sure if I'd ever need it, but that trick is getting stored.
+Dan Letkeman True, but that isn't really any better with a traditionally wedgie sled. Since their fences are moveable neither of them are zero clearance.
just a thought, why not make something like a folding ruler, which has two arms and you can adjust whatever the angle you want, rather than have multiple piece of triangle piece of guide. Don't get me wrong those CNC pieces look nice.
only drawback I can think of (versus the other design) would be maybe the holes wearing out some after a very long time, enough to throw off the precision of the angle
Tom Cummings you can harden the wood fibers in the holes with a few drops of cyanoacrylate (superglue). Bolts/studs with non threaded shank portions would further reduce wear.
Came across this just today. Your sled idea makes so much more sense to me. I've never done any segment making or turning so take my question with a grain of salt. Is part of the issue with the gaps in the segments (on your first-fourth tries) due to the inconsistent overhang on your cuts? I would think that if there was a stop block of some kind before your blade so each overhang is the same, wouldn't that help with gaps? Probably not. It's been too many years since high school geometry.
+akw825 In theory, the angle is all the should matter. If each of the segments is exactly 30°, then 12 of them should add up to 360°, regardless of length. However, in practice it is difficult to place them correctly to make this come out right. (A longer segment has to be set out from the middle in order to fit right) So you're right, if I cut them all to the exact same length it would be easier to get them lined up.
Very well done video. Most everything is explained very well. Im not sure why you installed the T track though. I thought it was to hold a sliding bolt for the angle guide, but in 5:43-5:45 the bolt coming up through the angle pc is clearly closer to the jig edge than the T track. What is the T tracks purpose? Is it solely to hold the 45 pc later as shown at the 6:20 mark? thx
You can remove the wedge fences altogether and use this sled to joint the edge of a crooked board. So the T-track is there to use with clamps to hold said board in place. It’s also used while making the wedge fences themselves, as I showed.
+Pierre Mouawad Yeah, that's what I'll be doing. I just used the table saw method to show the alternative. My machine isn't quite good enough to make them perfect on the first try though.
This is how I built mine. Waiting for the day I would find out “the hard way” why it isn’t done like this. The day never came! Thanks for the affirmation!
Thank you very much...this is a great thing to have..!!!!! Thank you for explaining everything in detail.. Looking forward to more great projects from you. Keep up the good work. Jacques Mostert Cape Town South Africa
Jeremy, could you use your laser cutter to get a more precise template? Now, I don't have a laser cutter--so i appreciate your explanation! But, for you (Mr. Laser Owner), is a laser-cut template accurate from the very start?
I wonder if the same principles can be applied to a tapering system for cuts along the length.. Thinking, thinking... Oh my brain hurts now..Time for morning coffee..
Excellent Project... The only thing I see that may or may not be a flaw is when you change segments patterns. It just seems to me that there is no real way to get the Segments back to where it was originally set unless I missed something. The more you put the screws through the holes they will always cut out a bit of board and over time could elongate the holes. Or as you tighten the knobs down might shit the template or segment pattern a bit. As you said a tiny error adds up quick. So my question is, how do you replace and change the pattern and still line things up? What I was thinking was possible adding a 3rd secure point. That way the more secure points you have the greater chance you have of lining things up again and again despite the wear and tear of the metal on wood action. Just a thought... I look forward to your reply.... Cheers....
+Paul Bialozor The angle that the fence/template is mounted on does not make any difference on the angle of the segments. Think about it. If you're making a picture frame with mitered 90° corners, one side can be cut at 44° and the other at 46°, and joint will still fit perfectly. All that matters is that the front and back of the fence are the correct angle relative to each other.
Yes I see what you are saying here with regards to a 90 Degree corner and agree. But are you saying if your jig is off by a little, as you mount and unmounted the jig over and over, that 44 and 46 when factored over 12 Pieces (Speaking figuratively using your numbers on 90 degrees knowing that 12 pieces would be a completely different number) that some error would not be present? I find that hard to believe. Just seems to me that some error would occur. To make a segmented piece and you divide 360 by 12 and each piece has to be exactly 30 Degrees divided by 2 or 15 Degrees to ensure each angle side lines up. If you cut 16 and 14 degrees because your jig is off just a bit, I doubt over 12 pieces they would line up in the end. I am just trying to grasp the concept of your wonderful jig here, not trying to argue with you in any way...
Paul Bialozor Ok, think of it in an extreme way. This is often the best way to wrap one's brain around something like this. In the case of a 12 segment ring, you could mount the fence 15° off and it would still work. One end of the segments would be cut at 0° and the other end at 30°, multiply by 12 segments and it still comes out to 360. Each segment just needs to measure 30° total, and that's all that matters. Now of course if you actually did this, it wouldn't look right. All of the wood grain would be spiraling around in a sawtooth pattern. So for that reason it's a good idea to be within 1° or so, just so it looks right.
Very Nice! ! only a question ... It wasn't possible Cut the wedgie ( at the First attempt to find the right angle) with you cnc machine? I don't know... maybe it was more precise and Close to the ideal Cut. Sorry for My english😂😂
It's Matthias Wandel's design. Search RUclips for Matthias Wandel's 16" bandsaw and you should find his video(s) about it. It's a pretty good saw for the investment, if you have the time to build it.
I noticed your lathe. Very nice. I picked one up at a school auction for $75. Had the tail vise but was missing the banjo which I could never find. Ended up selling a few parts then scrapping the bed. Curious as to where you found yours.
Quick question: why can't you just create a single fence and flip the piece you're cutting? I'm really impressed how you're really coming into your own. Your videos and content are a lot more polished and it shows.
+Paulo De Oliveira That would basically be a miter gauge then. The thing that makes this sled work so well is the relationship between the front and back fences, and it has nothing to do with the relationship between the fence and the sled. Because of this there is no setup; the fences are just roughly mounted on the sled and the only precision parts there are is the front/back of the fence. Hope that made sense... Thanks!
Did the CNC ones come out seemingly perfect ? Would be interesting to test the precision of the CNC in terms of how many segments you can reach while keeping a perfect match...I'll try that on mine
Awesome, I may have to try this. With my sled I am limited in the width of the stock I can cut up into segments, your solution solves this problem. I really like how this sled concept is evolving.
+frank howarth
Hmm, I hadn't thought about the stock width advantage. Thanks!
As I was watching this video, I was thinking, this would be very helpful to Frank H. I wonder if Frank has seen this. Question answered
* Clicks over to frank's channel, eagerly awaiting the video... *

Has stock tear out at the back of the sled been a problem? Or does holding another scrap piece behind it prevent it?
BRAVO Jeremy. Through no fault of the original inventer of the wedgie sled he, like so many other inventers, are so in tuned into what they are creating that at times they can't see the more simpler way of going about it.

I like that the fences are also zero clearance with the blade.
Er hat deine Idee nur umgeändert 😀

Would you consider sharing the CNC file? Awesome work, man.
Great alternative, Jeremy! I was just looking at making one and now I have some options
Wow, Jeremy, you’re quite the machinist. It was a pleasure watching you give meticulous detail to this project. Bobby 🤗
How simple, why didn't I think of that???? Well done, that's for me.
Nice! I want to try a segmented bowl soon and I think I'll need to implement this. Thanks!

I really like your presentations. Many thanx.
Yeah, math is probably the best way to set up the angle of the wedges...
Looks like it works well. I think that really the only downside to the method is that the two sides must be parallel as you mentioned.
Why is that a downside? If you need the jig you probably have a table saw.
Thank you very much for the clear explanation. Now I do not need to buy wedgies and can make them myself . You have always excellent ideas . You are always honest and are not aiming to sell any thing🌹
Everybody in the WW community is: Do this like this, and like that.

And it turns out awesome. Great job!

Hmm, could you give me an example of one person that is "do it like this and like that"? Because I can't think of anyone and you even claim it is everyone.
you're right. It's called exageration. Humans do this all the time. See, I just did it.
Fred said that on Apr 4th 2016 at 4:32 pm.
Sharp as tack, as always. Boy genius. Wish I had that head of yours.
Another great idea! Incidentally, I hadn't seen a router used to make the cutout for the bolt head. I'll have to try that. Thanks for all you do.
I was just about the tackle a wedge sled. Perfect timing! I like it.
+Dustin Penner
Awesome! Thanks!
I wood like to still see your take on it.
Awesome explanation. I didn't get it when Frank Howarth did it with the split fences.
Thanks Jeremy! A very nice project. Maybe the main lesson to learn is that many projects require a trial and error approach.
Neat! I bought several of the "wedgies" to set the segment angles. I can use them instead of cutting ones like you did. I think this is a brilliant design change.

I don't even turn and I think I agree with you about this being simpler to use.

This is a much better solution if you have a zero clearance base plate. Single guide rail reference is just much easier to set up and be consistent with.
Nice work Jer.
The only issue I see is not having the fence behind the blade as you mentioned in the video; however, I think one could fix the issue by putting one of Marius Hornberger's Cam clamps into the T-Track and tightening it down to the track. Then one could safely and quickly hold the stock against the fence. You said you were comfortable holding so may not be a solution you need.
+Eric Smith
Yeah I'm comfortable with it, but a cam clamp or a toggle clamp would also be a good idea.
Nice Job Jeremy, I think if you added a tail onto the 45 degree board you could attach it to the second bolt and keep your current design.
+Marty Josephson
The bolt can't even be there because the stock will hit it. Much less a tail.
Yep, your right, how about a miter slot then?
Great video as usual, Jeremy, I love how you explain things. Now, about that bowl at the beginning... Are we going to see a video on that? I like the design.
+Johnny West
Thanks!
I made that bowl quite a while ago, and I posted about it on my Instagram at the time. So you can go dig through my Instagram archives and see a little more about it.
I just ordered a wedgie from the originator. And I was thinking of just attaching it to my sled. I thought I was on to something so I came to RUclips to see if someone beat me to it. Yup. Good job
ABSOLUTELY BRILLIANT!! Some of the earlier comments are great.
The simpler sled is also more flexible and adaptable - with some added design features, it could become the only sled you will need!!.
Seems like a very good solution for making segmented clock faces. Thanks for the insight.
Excellent description and explanation! I also like the improvement you mentioned. Kudos!
+Sean Flanagan
Thanks!
use a 3rd screw for the 45 degree? for the others the 3rd screw wont hurt.
+Joerg Gebhard
*Facepalm*
Of course! That's a way better idea! :) Thanks!
I always enjoy your videos--very well thought out, filmed and explained.
+The Warped Board
Thank you!
You have a bright future ahead. Great thinking.
Hi Jermy I like all your works very accurate and super professional there any more clips of yours doing furnitures and other wood work ?
Nice job. I think to reverse the bolts you could sink large all thread nuts in the base then cut them flush with the top Then you could use the bolts to hold it down
Hi Jeremy
Your comment about mitre gauge accuracy I would challenge. As the old adage states you get what you pay for and if you buy a low cost mitre gauge it will more than likely not be accurate but if you buy one from INCRA out of Dallas you can get an accurate one for reasonable money and for a little more you can get even more accuracy. That is why they sell one hell of a load of them.
Your wedgie sled has some benefits and I shall make one because my saw table does not have a standard mitre slot 3/4" by 3/8", but that is because in Europe folks like Festool set their own standards.
Cheers
+Bawdsey64
You're right, a better miter gauge would be a different story. I have three of the style I showed and they are all junk, but they are all cheap ones.
However, I am quite sure there is no miter gauge accurate enough to make a perfect 12-segment ring. As I said in the video, a half thousandth angle on the fence is unacceptable.
There is at least one huge disadvantage. With the wedgie sled you can scew the prices to the blade, so they aren't 90°. Doing that will give you almost the same pieces but when they glue up you'll see they spiral away from the center. You can make awesome patterns.
You can still do that with your sled if you remove one pivot point.
Great video. Might have to rebuild my sled now.
You also blew my mind with having the two heads on the combination square at once. Not sure if I'd ever need it, but that trick is getting stored.
+JWR Woodworks
Thanks!
I've gotten a ton of use out of that protractor head and I've only had it a few weeks. I definitely recommend that attachment!
Great Sled, Jeremy. I also liked that CNC touch you threw in.:)
+CrazyRussianWoodShop
Thanks!
GREAT jig Jeremy. Very well thought out and multi purpose, which is ALWAYS a good thing.
+Sebastopolmark
Thanks!
An obvious flaw would be that you will get tear out with solid lumber because the second cut is not supported by a fence behind the piece of wood.
+Dan Letkeman
True, but that isn't really any better with a traditionally wedgie sled. Since their fences are moveable neither of them are zero clearance.
Dan Letkeman that's easily overcome with a sacrificial piece. just butt it up against the piece and cut through both of them.
Hardly an issue after you put on a lathe.
Excellent! You should sell these.
Genius. I wouldn't be surprised if you could sell these... I'm not a turner, but even the 45° segment wedge might be worth some coin to me!
+Jeremy McMahan
Well, I showed you how to make it! ;-)
Yes, yes you did. And a very good description too. :-)
The saw blade can push the board away from the angle in your design I prefer the pressure of the saw blade holding the board.
just a thought, why not make something like a folding ruler, which has two arms and you can adjust whatever the angle you want, rather than have multiple piece of triangle piece of guide. Don't get me wrong those CNC pieces look nice.
Excellent video, a must build for the shop. keep the videos coming.
Köszi,már rég keresek valami ilyen megoldást :D
only drawback I can think of (versus the other design) would be maybe the holes wearing out some after a very long time, enough to throw off the precision of the angle
ah but wait, that wouldn't matter would it, it would just make the wedges alternately different
+Tom Cummings
Yeah it doesn't matter, the only thing that matters is that the front & back of the wedge are right relative to each other.
Tom Cummings you can harden the wood fibers in the holes with a few drops of cyanoacrylate (superglue). Bolts/studs with non threaded shank portions would further reduce wear.
The inserts would solve the problem, I think.
Came across this just today. Your sled idea makes so much more sense to me. I've never done any segment making or turning so take my question with a grain of salt. Is part of the issue with the gaps in the segments (on your first-fourth tries) due to the inconsistent overhang on your cuts? I would think that if there was a stop block of some kind before your blade so each overhang is the same, wouldn't that help with gaps? Probably not. It's been too many years since high school geometry.
+akw825
In theory, the angle is all the should matter. If each of the segments is exactly 30°, then 12 of them should add up to 360°, regardless of length. However, in practice it is difficult to place them correctly to make this come out right. (A longer segment has to be set out from the middle in order to fit right) So you're right, if I cut them all to the exact same length it would be easier to get them lined up.
So you can eliminate the need for the bolts - you could just use two track bolts in slots, one on the front and one for the back, right?
+Scott Baker
You could, but I'm just a lot more comfortable with the two bolts. It's more secure.
Scott Baker ，
Just found your channel . Excellent, very useful .
Very well done video. Most everything is explained very well. Im not sure why you installed the T track though. I thought it was to hold a sliding bolt for the angle guide, but in 5:43-5:45 the bolt coming up through the angle pc is clearly closer to the jig edge than the T track. What is the T tracks purpose? Is it solely to hold the 45 pc later as shown at the 6:20 mark? thx
You can remove the wedge fences altogether and use this sled to joint the edge of a crooked board. So the T-track is there to use with clamps to hold said board in place. It’s also used while making the wedge fences themselves, as I showed.
why have i never seen anyone cut a dado for the runner, just great
I don't have a cnc and i never used one but i hear how accurate they are. Wouldn't it be better to cut the angles on the cnc, just thinking.
+Pierre Mouawad
Yeah, that's what I'll be doing. I just used the table saw method to show the alternative. My machine isn't quite good enough to make them perfect on the first try though.
I would use the small end towards the blade..... otherwise you need to set up two stop blocks to cut the segments....
This is how I built mine.
Waiting for the day I would find out “the hard way” why it isn’t done like this. The day never came!
Thanks for the affirmation!
Why didn't I discover your channel earlier? Amazing job, thanks a lot!
I make my wedge from a laser cutter perfect angle every time
Thank you very much...this is a great thing to have..!!!!! Thank you for explaining everything in detail.. Looking forward to more great projects from you.
Keep up the good work.

Thank you!
Dude you've got some really rock solid designs and I like the your thoughts on stuff like push blocks on the table saw. Keep up the good work!
+SasquaPlatypus
Thanks!
Jeremy, could you use your laser cutter to get a more precise template? Now, I don't have a laser cutter--so i appreciate your explanation! But, for you (Mr. Laser Owner), is a laser-cut template accurate from the very start?
I don't have a laser cutter.
I wonder if the same principles can be applied to a tapering system for cuts along the length.. Thinking, thinking... Oh my brain hurts now..Time for morning coffee..
Very nice design and build video. Thanks
Excellent Project...
The only thing I see that may or may not be a flaw is when you change segments patterns.
It just seems to me that there is no real way to get the Segments back to where it was originally set unless I missed something. The more you put the screws through the holes they will always cut out a bit of board and over time could elongate the holes.
Or as you tighten the knobs down might shit the template or segment pattern a bit. As you said a tiny error adds up quick. So my question is, how do you replace and change the pattern and still line things up?
What I was thinking was possible adding a 3rd secure point. That way the more secure points you have the greater chance you have of lining things up again and again despite the wear and tear of the metal on wood action. Just a thought... I look forward to your reply.... Cheers....
+Paul Bialozor
The angle that the fence/template is mounted on does not make any difference on the angle of the segments. Think about it. If you're making a picture frame with mitered 90° corners, one side can be cut at 44° and the other at 46°, and joint will still fit perfectly. All that matters is that the front and back of the fence are the correct angle relative to each other.
Yes I see what you are saying here with regards to a 90 Degree corner and agree.
But are you saying if your jig is off by a little, as you mount and unmounted the jig over and over, that 44 and 46 when factored over 12 Pieces (Speaking figuratively using your numbers on 90 degrees knowing that 12 pieces would be a completely different number) that some error would not be present? I find that hard to believe. Just seems to me that some error would occur.
To make a segmented piece and you divide 360 by 12 and each piece has to be exactly 30 Degrees divided by 2 or 15 Degrees to ensure each angle side lines up. If you cut 16 and 14 degrees because your jig is off just a bit, I doubt over 12 pieces they would line up in the end.
I am just trying to grasp the concept of your wonderful jig here, not trying to argue with you in any way...
Paul Bialozor
Ok, think of it in an extreme way. This is often the best way to wrap one's brain around something like this.
In the case of a 12 segment ring, you could mount the fence 15° off and it would still work. One end of the segments would be cut at 0° and the other end at 30°, multiply by 12 segments and it still comes out to 360. Each segment just needs to measure 30° total, and that's all that matters.
Now of course if you actually did this, it wouldn't look right. All of the wood grain would be spiraling around in a sawtooth pattern. So for that reason it's a good idea to be within 1° or so, just so it looks right.
Good job Jer, I like it.
Fantastic improvements. Great explanations.
+Greg's Garage
Thank you!
Very Nice! !
only a question ... It wasn't possible Cut the wedgie ( at the First attempt to find the right angle) with you cnc machine?
I don't know... maybe it was more precise and Close to the ideal Cut.
Sorry for My english😂😂
Why don't you make a video on your band saw which I saw in the background of this video and it been a while we have seen any new upload
Can you make sets of the weggies to sell? I don't have a cnc and as you said the y can be hard to make.
Why measure angles when you can measure distance instead?
Do you have a video for your bandsaw. I see it in a lot of your videos, and it looks intriguing thanks.
Love your videos
It's Matthias Wandel's design. Search RUclips for Matthias Wandel's 16" bandsaw and you should find his video(s) about it. It's a pretty good saw for the investment, if you have the time to build it.
I noticed your lathe. Very nice. I picked one up at a school auction for $75. Had the tail vise but was missing the banjo which I could never find. Ended up selling a few parts then scrapping the bed. Curious as to where you found yours.
+Robert
Local Craigslist!
Love your modification to the Wedgie Sled. I would add one feature. I would add an arc so the wedgies can rotate, allowing a spiral look.
That’s a good idea. But I think I’d just make another wedgie to produce the spiral, otherwise when you rotate it you lose the zero-clearance edge.
excellent video! glad I found your channel!
Quick question: why can't you just create a single fence and flip the piece you're cutting?
I'm really impressed how you're really coming into your own. Your videos and content are a lot more polished and it shows.
+Paulo De Oliveira
That would basically be a miter gauge then. The thing that makes this sled work so well is the relationship between the front and back fences, and it has nothing to do with the relationship between the fence and the sled. Because of this there is no setup; the fences are just roughly mounted on the sled and the only precision parts there are is the front/back of the fence. Hope that made sense...
Thanks!
great no BS instructional, wld like to see more!
Did the CNC ones come out seemingly perfect ? Would be interesting to test the precision of the CNC in terms of how many segments you can reach while keeping a perfect match...I'll try that on mine
+nitsn
My CNC is not that precise. The fences off the CNC still required truing using the table saw. Hopefully my next CNC will be better :)
Thank you for your reply, that's interesting to know. Your videos are great, you have all my admiration. Keep going !
