Hey everyone! Today’s most popular comment is that I can use an end stop at the end to repeat the X position on the next part. You are right, I can. Now nobody needs to suggest that anymore, thanks. 😬
Just wondering why not start the center hole in the v-block with a 2 flute end mill until it got to the point where you could use a drill?
Effectively its only a clearance hole for other drills so in some ways it doesn't need any real accuracy at all or does it?
Its a nice fixture conceptually. 👍👍👍👍👍👍👍
I really appreciate the rhythm and pacing of your videos. I know it can be super tricky to get it just right but I think your videos are fantastic.
Aw! They beat me to it!
I find it amusing that you post a *_"Cross Drilling Fixture"_* around Easter time.
:
Hey Quinn, try Renaissance wax for preserving parts, it’s a micro crystalline wax that’s excellent for protecting any parts whether they’re blued or not, from firearms to photos, it’s really great stuff, very versatile
I have never used, touched or even seen a metal lathe or mill in real life. Yet I subscribe. And I enjoy.
Oh me too. If you haven't yet, check out This Old Tony - also enjoyable for a non-machinist. A full year of binging Blondihacks and This Old Tony though, and now I'm constantly browsing online marketplaces for used lathes and mills that I can't afford or fit in my garage.
Oh I reckon there’s quite a few of us in this club :) Come in, sit down, take a biscuit, we’re probably completely harmless 😂
I’ve never seen the ocean.
Get one of each. You will have lots of fun with them. You can get bench top lathe and mill at Harbor Freight.
Bridgeport Vertical Mills and Clausing or South-Bend, or Cincinnatti Horizontal lathes are where it's at. They are fun to operate, well...(I learned on them before x/y technology came out.)
The hardest part about watching a Blondihacks video is having to wait for the next Blondihacks video after you're done.
"Chamfers are what separates us from the animals" would make a great Blondihacks t-shirt
This is my life philosophy as well! :-)
Quinn is an absolute LEGEND. I learn more in a single blondihacks vid than I learned in my entire school career.
Flycutting is quite satisfying, even if hand fed. I liked it 50 years ago, and I like it today. _Cross-threading_ fixture is the story of my life.
I want to thank you from the bottom my heart, sincerely a member of the metric gang.
Someone is wanting a Bridgeport for christmas I gues by you mentioning it so much ;)
was what I was thinking, but do she have room for it?
@@steamcastle She will probably make room if she gets one
And where would it go?
Sounds like a Go Fund Me campaign might apply here. :-)
I've been wanting a Bridgeport vertical mill fitted with a woodruff key cutter, since the 1970's !!!
THANK YOU, YOUNG LADY; FOR A WONDERFUL VIDEO !!!
Listening to you talk is SO enchanting ! I guess is the right word to use. I was a Machinist, Tool & Die Maker & working in Job-Shops, then changed crafts to Electrical field, but stayed a Tool Designer for half a century for the company I was an electrician for, as well Journeyman Electrician...and a bunch of other stuff.
Listening to your shop language drags a grin onto my old face ! I don't hear folks talk like you do, speaking of machine shop jargon! It's plumb refreshing to hear! (one of my student test projects, was making a "Fly-Cutter". When you said something about worrying about the cutter coming out into your face or into the floor and into your face, reminded me of something our instructor had us do, that isn't in the run-of-the-mill fly-cutter...He had us add a pin across the slot clamp. Then you would grind a "V" across the cutter. That "V" would go right under the pin and serve as a safety against it EVER coming out. It was easy enough to do, and was cheap insurence against a piece of tool-steel tumbling thru your brain !!! Please pass that on. (you can also machine a relief "V" on the tool clamp) which ever...as long as it prevents the tool to slide in the slot. If you wish to extend the tool, just grind another "V" groove in the tool.
You mentioned using a drill bit in a collet...provided you have the right sized collet for your bit...Well, tye tech school I went to, (night school in another high school while I was going to high school in the opposite end of town), taught me to use a precision (little South Bend lathe, and using a 1/4" square bit with a Carbide Tip), and turn bits down to use the collets you have. You never want to severely drop the size, for strength issues, but by doing this, you can have a good set that can be used in a standard chuck or in the lathe tail-stock chuck or in the power-head chuck or collet in the lathe or vertical mill or drill-press. It is advisable to get a NEW SET and turn the whole set. ( Label the set box, on the bit holders, with the size of collet that these bits fit. All on one color code fits such & such collet. ) Oh, and CRISCO vegetable shortening is the BEST tapping agent for steel. It's also great for power-tapping ! Turpentine for Aluminum.
Bill, from Tn. 🇺🇸
I suppose, if all of your small parts, that you need to hold on to, have the same dimensions, you could clamp a stop block on one end and only have to edge find once.
Very cool little Jig, Quinn...Thanks much for sharing it!
Quinn makes a thing, thing makes another thing.....Quinn berrry happy ,and makes a video thing, video thing make brian happy. Happiness all around.
LOL! omg i just vibrated a drawbar onto my foot last night...too dang funny.
Unintentionally non-family friendly tools are the best tools.
i don't know what you mean by that sir my 6yr old boy loves milling though not so much the set up if there's a lot of indicating to be done but he has come along way from 2 yrs ago when he just wanted to crank handles and make chips fly
I'd call that one the CNB ruler.
@Doubleboost collet wrench ? No? ---- OK moving swiftly on .
It's close enough to a "fish scale" so I chose to ignore any further observation xD
What is the actual name of of this comically shaped tool? It is something I have never seen before.
These videos are never not good. Thank you for being such a good teacher.
That little mill does great in steel. Excellent tool.
Your videos are so much fun, learning so much! Quinn, I know where I have seen you before! You were Thing on the 60's version of The Adams Family! So hard for celebrities to hide!
I think your results are far better than those a "drunk canadian amateur" could achieve.
@@Nono-hk3is There are Sober Canadians?
"it's also a cross-threading fixture" - I guess maybe not everyone can be as good as me at freehand cross-threading. Just comes naturally to me 🤣
Great video as usual!
I thought I was the only cross threading fixture. Feels good to not be alone anymore.
Quinn! you for got all the tappy tap's!!!
I noticed that too, and assume she took a mental health break to prove that she is more than the sum of her catchphrases. I respect that. She knows we're all saying it in our heads anyway.
Honestly, I just keep forgetting when doing my voice-overs. 😅
Love how concise your video intro is. Thanks for not wasting time on every vid.
Hey Quinn great video quick tip to get a drill to fit an R-8 collet. Most of the black oxide drills the shank on those are soft enough so you can put in the lathe and turn down to fit a collet.
Good tip!
Quinn, make a bar with pins to sit in one pair of the precision holes you put in. Drill it for a fine thread screw that will act as a stop on a small part. Now the fixture will let you produces a series of parts without having to relocate along the x axis!
Sorry - didn't realize so many others had already suggested this.
Happy Canada Day
Another great project, Quinn. "Chamfers are what separate us from the animals." 😅
I want that on a bumper sticker.
@@nefariousyawn Me too!
Yes, that was a great saying (at 21:00) and thank you for the comment, Daniel:)
Hello, I'm Paul, I enjoy watching your videos, I'm in the process of getting a new place and setting up a new shop. Two things I have noticed, 1. Your block is missing small springs to keep the top clamp up while placing the part in the V groove, and 2. A small or medium sized air compressor makes a bunch of small tedious tasks quick and easy. Please keep up your awesome videos, your newest fan, Paul.
When I decided to mount a Z-axis drive to my PM 1054 TV milling machine, I had to cut off the factory shaft and drill a hole thru the part of the old shaft left in the machine. So one of these fixtures is the FIRST thing I made with my new milling machine. Yours is better, of course, but I got it done, and mine is very nearly identical to yours in all relevant ways.
You may be a "drunk Canadian amateur" but you're the best one we've got and we love you for it.
I used the "I can put a chamfer on it, since that's what separates us from the animals." phrase today with my wife. She gave me a look, and that was all I needed to think, "success". Another winner here, Quinn.
We’re all animals.... but chamfers & fillets separate us from savages. 😉
I invested in a set of screw machine length drill bits to solve the height problem on my mill (I have the same one as you). As a bonus, they're a bit more rigid too.
I second this.
You call out the depth of cut numbers and I feel a whole lot better about the performance of my little Amolco mill. Thanks again for
for a job done in the real world . Happy Easter to you and yours .
I think that was the first time I’ve heard you confirm you’re Canadian, hello from your southern neighbor! Great video as always...
Brilliant work. Some holes tapped in the left and right side of the block, make a flat plate, bolt it to the side and then have a bolt with locking nut and there would be no need to edge find on the side of the part on the X axis if you're drilling multiple parts of the same dimensions.
Awesome. I am not a machinist so bare with me. This tool would be the bees knees for drilling shotgun barrels for a bead with a hand drill. I know, I know it's easy enough to do with a basic bench top drill press but many of us don't have one and we don't want to buy one. Optimally the fixture would utilize bushings but for the task as stated, the clamp would only be bored for the appropriate drill bit. Bye the way I'm glad I found you again as I followed you up until you pulled up stakes. For some reason I thaught you had given up on you tube . I'm glad you are still here! Now my life is complete again.
I have been machining for fun for a few years now with a 3n1 drill, mill, lathe and realize you have a great amount of knowledge to impart. Great videos. Keep em coming !
Wow, a no nonsense, friendly, natural talent we can all share. Thank you, that was great. From OZ.
This is a great project! Worth the time, effort and experience for the newbie!
You really need a full set of stubby drill bits! My 1980 mill/drill has no knee and a round column, so I'm constantly fighting the short tool/long tool battle. Stubby bits are a lifesaver!
Yah, a set of screw machine drills would be a good investment
8:15 It's a rocket ship!
I don't think that is the rigid interpretation :)
🚀
Nice fixture and total entertainment!!! Thanks for sharing !!!
As usual, I learned a lot and I enjoyed watching a precision fixture appear before my eyes.
First video of your’s I’ve watched but I’m impressed. I’m not a machinist but I dream of being one someday. I could watch your vids and get pretty close to being one I think. Great video and editing skills along with a nice, crisp, self-deprecating style. You take something that’s basically boring and make it fun.
Your videos and TOT are why I'm currently going to Machinist School(started 3 weeks ago). I absolutely love the delivery and content of your videos. Keep up the great work!
could make a little end stop assembly that drops in to those precision corner holes if you were really keen.
I was just thinking this same thing as I was watching.
A very good fixture.
I just love that you keep everything clean. I wish my coworkers could do the same😤
I've been a fan for a while, but if I hadn't been, the "Cheap Chinese mill and a drunk Canadian Amateur" line would have won me over!!
I am surprised you need a cross threading fixture, I can cross thread without trying - no fixture required! Good vid as usual.
Handy fixture Quinn.👍👍
Don't count out the small mills. I've had great success hogging out steel with a 3/8 YG-1 Tank Power roughing end mill. I was shocked at how well it ran in the G0704.
Rockstar patron "Dagobert Krikelin"...that is just an awesome alias. Kudos to him/her.
Edit:
Great little project Quinn, thank you for sharing.
..and happy Easter.
Your thought process is much very admired. Thinking a lot, saves a hell of lot of swarf.
I watched Your Steam Builds.Great Work.As a machinist for 40 plus years and a Steam Locomotive builder Your work is very Impressive.I know the struggles with castings and You with patience do a Epic job.
Well done both for content and production quality!
I have not read all of the comments so maybe this has already been suggested: If you cut the V first, clamp in a dowel, and then use it as your reference to cut the flanks, alignment will be ensured. Finish cut one side, rotate the block 180 degrees, and make a second finish cut.
For small V cuts, you can use a spotting drill on the block set horizontal.
I wonder if you could drill the central hole first, then, without touching the Y-axis, cut the V with the spotting drill. Cross drill and tap a piece of drill rod and secure it in the V through this hole. Then use the rod as your reference as mentioned above. Ah, your video is a great inspiration to me!
Joe Pi has yet another excellent video. This one is on squaring a block using parallels. After milling the top face and flanking sides, you are always supported by cut faces.
Not only are you very capable, but you also teach well. Well done
Spectacular job, as always. I love how perfectionist you are and how clean you work. That's LOT of dedication to make each one of your videos. Congratulations!
You are fast becoming my favorite machinist. Keith Rucker watch out!
You can also use a vice stop along with that to eliminate the need for the X locating of every part. Just a thought. I use one very often on multiple part runs. Keep up the awesome videos. I watch every week.
not much to say, great video as always, this content-free comment is here to drive up engagement numbers for my favorite channels.
I feel like a threaded hole on the side to allow you to attach your choice of adjustable end stop would be a great addition to this awesome little fixture
I was thinking something similar, however you can probably just place a magnetic indicator holder with the arm touching on one side of your first part to get repeatable part placement. I could be wrong.
Nice seeing an alternative design to a project completed in my early days of machining!
@blondihacks Just a thought, you should add some springs around the bolts, between the base and the top fixture. That way, when you have multiple parts to cross-drill, you just have to back the screws out a little and load the next part in. This should save time from completely removing the screws and removing the top, or having the top fall down everytime a part is removed.
Great tool. I will have to remember to make one for myself. Thanks for the video.
Very cool,good stuff
Quinn , The local beer distributor started carrying Moose Head so we had it at the east coast Quinn Dunki fan club meeting tonight a lot of the ladies like the long hair style you are sporting , and after that big math calculation you did , ( very Impressive ) A lot of the boys were wondering if you could help them with there taxes ???? Thank you for taking the time to make these videos.. Pete M
Another excellent video. The subject content and machining skills are equally matched with a flawless and smooth video/audio production that moves forward in a timely manner. Very well thought out from beginning to end. Two thumbs up!
Thanks Quinn, I'm actually going to make me one of these bad boys
Thank you!
I remembered watching this vid when it first came out , now I find I need one so it's off to the cavern , mine will needs be a bit smaller as its for 3mm pins but same theory should be good cheers Quinn
You could also tap a hole on the side for a stop with an adjustable rod for multiple parts.
Another great video with a great idea, “as is tradition”.
Me: "ooh a new machining video"
My wife: "ooh her hair's grown"
I honestly love that she will watch these with me though and follows along
She's a keeper! That's probably why you got married.
My wife is a big fan of Quinn, too. We watch pretty much every video together.

"As I always say: Chamfers are what seperates us from the animals" - hahaha, love it!
Very nice job
Very neat your good at this engineering stuff thanks👍👨🏻🏭🇬🇧
Great, another project to add to the growing list of stuff I need to make.
This video makes me appreciate my little Clausing mill. I really wish I had R8 spindle like you, but I don't have to worry about chatter nearly as much.
Hi Quinn. Nice video. One point I thought worth mentioning is in reference to your explanation of the need for an Undercut at the root of the Vee. While you are correct in that it serves to remove the need for the unattainable "perfect corner", anyone who has ever ground a Vee Block will tell you that its a bit easier to grind to an undercut vs a blind corner. Easier usually equals cheaper, therefore it's often more commercially viable as well. Keep up the great work.
I am so impressed with you and your work. And I love, love, love your sense of humour!! I too was raised on a farm, but we had much less in terms of machining and welding equipment than I currently own as a hobbyist. Go figure.🤠
Excellent project! Going to have to make one of these...or 2. One for larger stuff and one for model parts like small engines! Thanks for this one Quinn!
Looks great. I'm sure it's very satisfying to be able to make the thing that helps you make the thing you're making.
Thanks. I may make that. You voice thru your videos so smoothly. Impressive!

Drunk Canadian, totally laughed out loud😄
Hello Quinn,
Happy Easter to you... A very nice fixture and an enjoyable video... thank you.
Take care.
Paul,,
Nice work! I think you really need a boring head. They are super handy when combined with a tiny solid carbide boring bar.
I do have one, but it wasn’t necessary here (and honestly takes up almost as much room as the reamers). Some drill-length reamers would be a good investment though.
That rather unfortunate shaped non family friendly tool should be shared with your neighbor AVE. I could see him doing a small production run on the CNC just for laughs. Another good video, thanks for sharing!
Tremendous! Thanks very much for this. I like your meticulous approach and fearless dealing with the trigonometry! Nice and Machiney is a good way to go!
Interesting to see your method for locating the X and Z dimensions required. I did a project similar to this, to make a tap guide, and used trig to get my values. So many ways to work with triangles.
Handy, Nice work!
I don't understand the dislikes, I think you r awesome, u simplify for the lamen people like me, and I reckon other pro,s love your tutorial,s too, hmmm, I dontbunderstand some people.
LMMFAO Didn't even notice the 'Non-Family friendly shape' till you mentioned it!
Now you can’t unsee it
@@Blondihacks 🤣🤣
@@Blondihacks Next time just nonchalantly call it the CNB ruler.
@@Blondihacks Yeah, a bit like the pattern the Ever Given travelled b4 becoming grounded in the Suez Canal LoL
Thank you for what you do.
Whoa whoa, wait, I thought I would never use Pitágoras's theorem outside school... Hmm 🤔
Somebody lied to me!
Use your tooling holes to make a stop for your plethora of small parts to be cross drilled.
Ah the Saturday machining show
saturday morning cartoons for big kids
I'm in no way a machinist but like always this was so much fun to watch! Thanks so much Quinn.
Great design. This would have come in handy yesterday
you could repeat those small parts at the end, by putting a couple of pins in those guide holes in the corners and then a gauge block or something to suit.
