Something similar found in Euclid's elements and also used by Archimedes.
In the material handling Industry we would call this an overhead bridge crane. Commonly seen in factories and foundries.
The axis running the length of the wood is the bridge axis, which has a trolley axis that traverses the bridge girders that span between the two bridge rails. Then there is the hoist motion that allows one to raise or lower your load.
We live in a 3 dimensional world.
Y AXIS =Vertical Axis Up/Down
X Axis = Horizontal axis Left/Right
Z Axus = Depth axis Forward/Backwards
How long did it take going back and forth leveling?
First time watching, found it 2 B slicker than snot
Nice content mate! So happy to announce that I have gained financial freedom by investing in digital currency . Now I know that multi creation of various streams of income is the ideal Principle for financial sustainability.
I have secured financial freedom investing in bonds , equities , EFT's and some digital currencies .
The current altcoin landscape is characterized by extreme volatility, FOMO, dumps, and inflation. Professionals like Richard Waller offers a deflationary assets with protections for dumping and monetary incentives for holding.
@Victor Whaley . Wow I’m just shocked you mentioned and recommended Expert Richard Waller✅.
Richard Waller works as a consultant at Edible Health where I work as an operational manager. He improved our Customer Service system after failed attempts from many experts from Saylor foundations. He is best in blockchain/crypto start-ups.
Michael J Saylor offered him a free Certificate where he Learnt how to compile and analyze financial statements, determine the value of an investment, and evaluate a business and its competitors.
You crack me up. I enjoyed watching from start to an outstanding finish.
Both of your descriptions are by far the best instructions on how to make something I’ve ever gotten. For an Ellipsis jig and the router flattening jig! Thanks man, really exceptional!
I don't know which You Tuber I saw do it (possibly Modustrial Maker or Kim Tippen, not sure), but a good way to hold something down that can be easily removed when your done is apply a strip of masking tape to each surface you want to attach to each other, then use superglue one piece of tape to the other...instant 2-sided tape that has descent holding power but isn't going to mar either surface when it's removed...do this for each piece of double sided tape you would normally use to secure the work...
So in order from top to bottom it's
work piece
masking tape
superglue
masking tape
workbench
as long as you're careful to keep the glue from oozing out from between the 2 pieces of tape, you'll have no problem unsticking the piece from the bench...
What do you think of putting a traffic lights on that crossing 🤔 😜
Nice job
What's the brand of the sander with dust collector hose? Link? Thanks and more power to your channel!
How did you determine the size of your four bevel squares?
Yep I'm a router train guy now and I'm only 3 minutes 59 seconds into the video lol
must be a very close friend if he trusts you with 500.000 dollars worth of wood in 2x4.
For the flattening jig…. To adjust the rails, you can also run string lines corner to corner- the rails are parallel when the strings just touch where they cross. This is how we used to set door frames before pre-hungs were a thing.
What do you think about using shims to fix any inaccuracies in the rails?
Jason's quote: "Shut up and say yes to your friends." But what if your friend's table top choice was a glued up mess from a pallet? 😂
any friend of his would know better than use pallet wood!
21:01 Are you saying that your wife is flush on the bottom?
Don't worry, your secret is safe, I won't tell!
I think he was saying HE is flush on the bottom.
@@nakantor Well, in that case, they are a perfect match!
That's the way I heard the comment.
I literally don't have anywhere to even put something like this, but I still clicked, watched, liked, and commented, because this is the best wood working channel I watch.
There’s no way you watched the whole thing. It’s only been up for 8 minutes
@@Bourbonmoth Sheesh! No, I didn't finish watching it yet... but being the forward thinking individual I am I realized people would be reading my comment in the future. Being the astute youtuber I am, I realized it wouldn't make sense to explain to people in the future that I was GOING to watch the whole thing straight through. Now that I'm at 16:30 maybe I'll just pause and switch over to getting my new quote on policygenius.com.
🤣🤣
nah it went faster cuz you cut out the sanding bit
@@mrtaylorrose I found it so easy I watched it on 2x speed. I actually made the table top at the same time as the video played. I do admit I did skip the sanding bit too.. Now I have a heavy surf board till he uploads the next video to make the legs.
I was legit trying to think the other day how I might make one of these elliptical jigs for the router. Now I know! Thanks for the great tips and the awesome videos! But I don't know why Neil Patrick Harris would send you those 2x4s glued up like that! Such a noob!
Because he knew the final product would be LEGEN.....I hope you're not lactose intolerant.......DARY!!!
Do I want to you to read from a phone book? No. Would I watch a video of you doing it? Yes. Nice job.
I can't afford 2x4's Would Cherry or Maple work?
"Family Area" sounds a whole lot worse than jewels. haha
I am sorry sir, it is in fact illegal to make a "do nothing grinder" do something. You are gonna have to destroy that. Trammels of Achimedes are reserved for useless debauchery
I like that the trammel is also colloquially referred to as a 'BS grinder', which is amazingly appropriate!
@@jaymzx0 I was gonna say, where I'm from, when I was a kid it was the only time I was allowed to use the bullsh*t phrase...
@@DanielCooper1 Always a good point to make when studying this device in high school physics class 😁. It reminds me of when Bart Simpson was elated that he could say 'hell' when actually referring to Hell. You gotta love those little loopholes when you're a kid.
Very nice mathematical construction!
Yo, didn’t expect to see you here
It's gotten "the nothing grinder" as a name on RUclips, because you can turn it somewhat like a coffee grinder but nothing happens... Mathologer's 2018 version I like best: ruclips.net/video/7Fn-26Jmi5E/видео.html --- he shows pictures of old ellipse drawing jig as well.
Now we are waiting for wood working projects on your channel ;-)
Thanks Jason for a fantastic explanation of how to make an oval jig. I would like to share a method that I use on ellipse jigs and jigs. Instead of fastening the router base to the jig I drill a 3/4” hole in the jig and then use a router with a 3/4” guide bushing installed. The router remains oriented in the same direction as you rotate around the work so that your cord doesn’t twist with every revolution and any router that will accept a 3/4” guide bushing can be used. John Jensen
If you wanted to make the table longer, you can cut the slider that moves across the width longer, when the router is cutting the sides, the end pivot will be outside the width of the jig ;)
Yeah, that annoyed me too!
Am I not mistaken or doesn’t placing the pivot for the long side as far as possible, like he did, mean that if it was any farther out it would come out the end of the track? You’d need to make the jig bigger I think, and that point the router would want to cut the jig when it came to cut the short side. I think you’d have to cut the long side and then cut the jig down to get the short sides down.
@@jeremyspecce With the method i stated, you want longer reach on the lends, but keep the sides the same, the only way to do this is to have a longer bar without changing the pivot closest to the router, which means the other pivot needs to be outside the current jig without making the jig wider.
It may be the case that the other slider needs to be longer too as the jig is 'square'
@@jeremyspecce you're right, the track for the minor axis is as long as it can get already. The major axis track can be lengthened, but it would cause the shuttle on the minor axis to slip out the end every time the router approached the minor axis. To fix that you can make the minor axis shuttle longer to allow the pivot point to travel beyond the end of the minor axis track without the shuttle falling out.
Finally, you can build an oval river table!
Yes! The internet demands this!!! 🤣🤣🤣
I've made a lot of tops from dimensional lumber. Pine is very underrated as a table material. Sure, it dents and scratches, but it looks lived with. The ellipse jig is awesome and simple. And, I'm going to totally steal that router sled design. Thanks!
Ahem...that would be a router *train*...
I agree. I've made desks and even countertops with a 2x4 glue up. Yes it is cheaper material but if you are going for a rustic, worn-in look, other harder woods just don't cut it.
Oh My Giddy Aunt. I do hope you got a 12 pack of your favorite libation.
Your timing is incredible as I’m building an elliptical table top and had planned to figure this jig out on my own. Thanks for saving me time!
By the way, my kids refer to you as the “easy peasy” guy and love those lines in some of your other videos 😆.
I loved watching this old house and Norm abrams work shop when I was a kid .ive always loved to watch quality Craftsmen build all sorts of things that's why I started watching your channel it's great quality work but your humor makes it so much better .
Keep it up love your work
Asking for a friend… why not just rip it in half, run through plainer, reglue. You made a cool plainer sled jig. That’s a positive but if you cut down a glue seam this would have been done in 5 mins.
I agree. I guess the only reason that wouldn't be an option would be if you can't spare losing the width of the kerf of the saw blade.
I agree, but Id he’d done that, there would have been no need to show us how to make and use a router sled
The planer wouldn’t have made it flat without a sled for it as well. A planer reduces thickness and makes faces co-planer but does not make things flat on its own. That the job of a jointer.
@@jeanchapman1301 yep
Came to the comments to ask the same thing
Considering it is a chunk of 2x4's would it have been easier to cut it apart, plane both halves, joint both halves and reglue? (I guess if in a real time crunch, waiting for glue to dry could be an issue)
I thought about that same thing
I thought the same thing. You could just cut along an existing glue line.
Bets are on to see whether 'the friend' comes back in a few weeks asking that work up some legs........ That would also make a good video......
With oval legs, naturally... I'm waiting to see a jig for that.
Dang nowadays what would have been a cheap table top is now about $200! lol
Good job brother. I love seeing your work I'll show you my work sometime If I would do that. that would be for family because I don't have friends. And I don't want friends.
I built a "router train" to flatten a cut out from a maple tree. Worked pretty good. Now I'm going to make an elliptical jig.
I have built a handful of elliptical stairs over the years. I'm no math genius, but I thoroughly enjoyed having to figure it out, with nothing more than a book to understand an ellipse. Your jig worked very smooth, and I understand your fascination with how it works.
And at 5 minutes and 1 second in I'm disappointed that you have gone back to sled versus train 😂
Sliding doo-hickeys into thingy ma bobs is the funnest thing. Who'd thunk it.
If i ever dont understand anything will you remake the video for me? Cheers ta.
Mr. Moth (man). Great job. I love your videos with one exception. Please, please stop calling the mitre saw a "chop saw"! It is not a chop saw! A chop saw holds a grinding wheel or metal cut off discs and chops steel into smaller pieces. A mitre saw is a precision tool and deserves more respect!! Just my humble opinion. BTW...I'm spelling mitre correctly. You Americans can't spell. LOL!
Alternate method for drawing an ellipse: 2 nails, one string, one pencil.
Does you no good cutting it
@@gernblanston4956 Ah, c'mon, Gern. If you are clever you can figure it out and make it work for cutting also.
Don't think I didn't notice that train sounding music. Because I did. Nice job.
I mean, Can we be best buds already? Haha love the content. Without a doubt the most laid back, informative wood working videos yet. And I watch a BUNCH.
Omg! You used a do-nothing machine to do something!! Does that make it a do-something machine?
hmmmm. i would have cut that expensive wood in half then run both halves through the planer
Nope I was wrong again it must be train car forever now and if you say sled I will be sat inside 😂
I love everything you do. I will never do most of it, but I always learn something to use somewhere. You are talented in wood working and in entertaining.
Great video, I need to build an oval table for a client the issues is that they want it 9ft long and 3ft wide. In order to make an oval of that size would i need to make the platform larger, or the swing arm larger (or maybe both) Id appreciate any advice Thank you
I can only plop once a day, You're plopping all day long, You're a plopping machine!
This will work great on river tables and pallet wood furniture!
HAHA! Perfect timing.. 😀😀 I am planning to finish my 7ft. plywood tabletop. Working on it for over a year and this was my last headache... thank you so much!!
Stars and stones, that's a lot of 2x4 to flatten...
Yer a wizard
I was wondering if the "Hells Bells" was a Dresden Files reference! Looks like another Jim Butcher fan caught it as well!
Honestly tho, I've always wondered how oval tables are made without a CNC
I heard you call a couple of pieces with your sled “thing-a-ma-bobs” so I did some fact checking and discovered that they are actually “doody-gobbers”. Just letting you know.
I thought it was "thing-a-ma-jig"
Missed similes: it orbited like the moon around the earth, like the planets around the sun, like a forgotten rubber duck in the bathtub circling the drain.
I’ve only used spiral router bits a few times, why would you use a down spiral bit to cut the oval out, wouldn’t that put the chips back in the groove? I thought an up spiral was the flutes removed the chips up to the base of the router.
@@Dinger523 Thanks for the explanation.
X can be remembered as "across". Some people say "Y to the sky" but that's not good because Z is technically to the sky. Also, $2.50 shipping inside Oregon for a sticker? You bumped your head, probably along the X axis...
I prefer minor and major axis.
Very cool. In geometry class, we learned this type of ellipse construction was based on the "trammel of Archimedes".
And the wee slidy things are called shuttle. I was so pleased to see that someone made the association with Archimedes. I've made smaller versions and kids love to play with them, I do to, they are mesmerizing.
13 thumb downs…. Really must be a wood worker hater to thumb down this creator. Nice job as always
amazing stuff, but say not 'adieu', only 'au revoir'

Thanks for taking the time to get your whole intro filmed in one take! easy to think you can do it, a whole lot less easy to actually do it. nice and fluid dialogue too. much appreciated!
Trevor Philips?
What would we do without friends that love us? Or our abilities.
I love a good two for.
Love the sled idea. Thank you for showing that. Table top came out looking great.
You are a master builder, Mate. I love your work. And I love your sense of humor- you pretty well crack me up, thanks!! 😊💙😊💙😊💙😊💙😊💙😊💙😊💙😊💙😊
Having used my own hand made router flattening jig, in that situation I would have ripped the damn thing in half, used the planer, then glued it back together.
👏👏👏👏👏very good, very top congratulations
Most expensive slab of 2021..
Thanks so much for this absolutely fantastic video. I hope to cut a similarly sized oval one day and you've just made it so easy.
Great work!
I hope your friend realizes the lengths you went to and got you a nice meal at least. :)
Just one second, , , , , , ! Methinks maybe your friend quietly coerced you into building something from pallet wood 😱🤢
Great Jig, just found out today that Rockler makes a bigger base you can buy to expand the size of the Ellipse you can do. I made one like yours and learned you can make the sliders longer , like a foot or eighteen inches, just so they don't run into each other in the middle. Then you can cut longer and wider ellipses. You could have made his top use the entire piece both length and width. Lots of possibilities. Great video.
neat project....but a little above my experience level
'' i forgot to press play '' Maybe you should press Record next time... Nice Video! Keep it up.
Awesome video
I want a bourbon moth hat with a pencil holder!!!
i spent the last three nights trying to figure out how to make a jig to make elliptical window frames out of big slabs of wood from a tree that was cut in my father in law\s front yard instead of sleeping. thanks for this.
Man awesome job as usual!
Lol no wonder houses are so heavy to pickup. You’re a good friend. 👊🏼 Jigs make our lives so much easier. Do you happen to have a favorite router bit if you had this project planned? In a perfect world you’d want one that takes off more material width wise with each pass.
Omg he put the grain going the same direction on 3 of the 4 pieces! My ocd is high gear right now
I kept thinking - "He's playin', he won't leave it...
HAHA I had a small one back in the mid 60's that my dad made and we called it a BULLSH-T GRINDER, hehe
I bought a Rockler jig some time ago because , like you it was fun to play with until I found a use for it, a small oval table. I had the opposite problem that you had, it wouldn’t make a small enough oval for my table top. I had to make my Center cross section “do hickey” smaller by chopping the corners off. Biggest difference was I had a pile of black plastic saw dust. Seriously the stuff inside your head is very cool 😎!
It's a little small...is it little or small?
Pretty cool train jig. Wondering why you didn't rip it in half down a seam, plane the halves and glue them together again.
Everyone needs a friend like you 👏
I really love these videos. It’s starts off with a quest and along the way are all these side missions that add cool shit to your inventory
After watching your videos it does seem like you would really do that for a friend! Great job I love your work!
@bourbonmoth If they are just glued together 2x4s, why not just cut off 1 or 2 from one side so it fits your planer, then glue on 1 or 2 new ones after?
This is a good idea thank you for putting this in because I have a really big piece of Oak that I am making a coffee table out of and it is the end piece so it's round on the one side and flat on the other side when I cut it with my chainsaw so I'm going to build the same kind of thing and Lease flatten out the flat end and then see what I can do with the other end since its rounded I don't know if the jig will actually try to flatten that or not but I'll see what I can do I also have to figure out how I'm going to put the legs on I'm not sure if I'm going to use Oak to do the legs or go with some metal legs or not
Password 1234..😂😂🤔 only an idiot would have that as their password... That's the same password for my luggage
Spaceballs. Great movie😂😂
What's up? I'm glad you posted this! I wanted to do this and have thinking about doing this in my head but you're way cooler than I am! Lol
Nice. Makes me think back of a 80 inch by 40 inch oval table top I made using pretty much the same jig. Not quite as spiffy as yours, but it got the job done. Maybe some day I'll get to use it again....
Great video ... definitely making this jig .... awesome job .... thank you again
Jason, when I was a kid in the mid-1970s, my grandfather gave me a 5" x 5" piece of black walnut that had the grooves cut into it and the sliding pieces, a 1/8" x 6" x 1" piece of alternatively colored wood with a dowel glued into a hole on one end and on the bottom was a piece of paper the clued to the bottom that said the product was called, "The Do Nothing," I just looked on Etsy and there are a number of shops making something approximating the 1970's version; there's even a "Tremmel of Archamedias," that has pieces moving in and across at 45° angles simultaneously. You looked like you were enjoying the function of the "do nothing machine" so much, I couldn't help but recommend this to you. I recall as a third grader even being mind-numbingly intrigued by the device and no doubt wasted an accumulation of hours and days trying to get those two damned pieces to run into each other. Strangest thing that they never did, ha ha.
Love this jig, but if you connect the hold-down screw holes with a slot, you'll have an adjustable oval jig. It's advisable to add a ruler next to the slot for easy setup. Likewise, I'd paint one of the knows and run a line dyed the same color next to the track It is on, just for easier referencing when setting up the adjustable oval jig. Maybe you could explore that upgrade in a future video. I love your workmanship.
OK, silly question, drinking while I watch... so forgive if it's too stupid.... why 13 degrees on the dovetail... would 15 be too much? Keep up the great videos. I love the drink making one's also
Hmm...cut in half, run thru the planer and glue it back together....? No ? To easy...? Ok...anyway love your videos.
16:04 It would be better to flip the long/short sliders around so that between the first and second square there's a short piece and they both share a common side against the long piece. Then once those are glued up, move the long slider to the gap between them, so that the other two squares can butt up against it. That way the sliders can go smoothly end-to-end without any possible misalignment.
Another beautifully executed video. A nice gentle half hour in your company. Thank you Jason 🌞
Rather than the doghole setup you rigged, for both sides the more common way to do this is with the doghole setup on one side, then use wedges to get the workpiece nice and tight on the other side.... 😉
Also -- Would it not be easier to take a piece of wood and create the elliptical shape on it you want, then use that as a template for the router? Yes, it does not "repeat" easily, if you need to make a bunch of different ellipses of different sizes, but most people are not doing that... either they are making a lot of a specific oval or they are not making ovals at all.
The distinction is, it is markedly easier to make an elliptical shape with a pencil (this is a classical way to create an ellipse -- use two pins and some non-stretchy line -- look at the wiki article on "ellipse" look for "gardener's method"), then rough-cut it with a jigsaw, and then use a sander et al to shape it accurately.
Which is much much easier and less prone to issues than throwing the full router around in huge arcs.
Just a thought for those considering this process.
Here's a video showing how it works... mind you, a string may be "stretchy", so you are better off using something with as little stretch as possible -- perhaps some fishing line, for example, or other really really non-stretchy stuff. If the line stretches, then the ellipse can be deformed by more pressure on one part of the curve than on another.

(RUclips kills external links. You should be able to reconstruct the above into a valid link)
The line does the same job as the channels in the jig, constraining movement in both directions to a fixed value, which is actually one of the ways to define an ellipse mathematically (Yup, you just did MATH!! 😁)
Your "slidy dohicky" : truck : length should be 175% to 200% of the tracks width. Good idea to bevel the corners. Paste wax the sides and bottom of the track as well as the trucks.
Jason; Can you do a video on Planer blade changes for us brain dead beginners? I have a Vevor 13 inch planer. I don't know if that helps. But I love how you teach.
