I was a bit cross with you yesterday. I had a batch of parts to make, and I have developed a involuntary reflex. I cannot stop saying to myself, "I will start by facing off as is tradition", every single time !! If I start saying "Yahtzee" when parting off I will have no choose but to sell my machines or stick my head in the oven !!! 😀😁😂
As an non machinist, it's very nice to watch this and it is shown nice and simple (understandable). I understand there is a ton of skill and mistakes also repeats before you make it look that simple. Thank you for theese nice videos.
As a Machinist and Finish Grinder for more than 40 years on the Handles.You do a GREAT JOB Quinn.I watch all Your Videos.Keep up the Quest to Create.I also have a home shop and Love Making Chips.
Quinn, you don’t have to keep saying “look, it happens”. We’re lookin’, and it’s happenin’. Just got my first lathe AND mill two days ago, Ive been binge watching your channel when I should be sleeping. Thanks!
Gray Drafting and Design is going to be getting a lot of new business. While watching Quinn's video on fixturing, she showed a beautiful tooling plate and said that it was available at Little Machine Shop (LMS). I looked and is was available, so I ordered one. LMS is usually very prompt to ship, and I was surprised when it didn't show up in a few days. When I checked the LMS website again, I noted that the tooling plate was out-of-stock. I just got the plate two days ago. Apparently, LMS was inundated with orders for the tooling plate following Quinn's video and ran out of stock.
Awesome! I have wanted to make these clamps since I first used a set (actually, I wanted to buy them until I saw the cost of the brand-name clamp). They are great clamps but there is only so much I can spend before buyer's remorse sets in. These kits from D. Gray are a fantastic deal. Thanks for sharing and for taking the time to make a great video.
The labor to manufacture this type of clamp is a huge part of the cost. DIY (if possible) solves that issue. And yes, the kits from D. Gray are a good deal!
@@exador1337 ....Depends upon what you are looking for in your tools. The quality of the kit (if machined and assembled properly) appears to be very good. $37 for two will not get you near the quality of the original "Kant Twist", but if price is the deciding factor, then I guess you give them a try.
FYI you can actually get an ER32 collet holder on a backplate. That way there's no limit to the length of stock you can hold, but for what's at the back end of your lathe. I also found some ER32 collets up to 1"! You might also consider a ballbearing nut, which increases your clamping force. My next project is to make an adjustable backplate for my collet plate, in case someday the runout of the collets is too big. Keep up the good work!
I love these clamps! During my early college years I was working on a Drafting: Electronics certificate (for both drafting AND PCB design), and this was in one of my drafting design books that was used for class. I used the drawings and re-designed them in AutoCAD for my class and my teacher accepted it as bonus work! :D
Great video (as always) thanks. A trick I recently learned regarding removal of mill scale from hot rolled steel, is to soak it in clear distilled vinegar. I had a fairly large area to deal with on a plate and it worked a treat. Note: It helps if you can keep it warm. Still works cold but takes a lot longer. After 24hrs on a radiator, I was able to rub the scale of with my fingers.
@@russellstarr9111 I've been involved in spray welding in the past. Mostly with ceramic for seal surfaces. Later I worked for a company that manufactures and rebuilds centrifuges for waste treatment plants. Their own and other manufactures models. One of the premier shops in the country in that industry www.google.com/url?sa=t&source=web&rct=j&url=www.centrisys-cnp.com/&ved=2ahUKEwiM65KDv5_wAhWGWM0KHQ7hDaIQFnoECAoQAg&usg=AOvVaw3iuAKgrKhn7Y7pLUzphjrC The stuff we sent out for spray weld there was a tungsten alloy and ground.
Nice project. I have been making small parts from hot rolled plate. After shaping I soak then for 12 to 24 hours in vinegar. A light scrub removes most of the residue and a quick pass with the random orbital sander makes them look amazing.
That is a really nice kit. I may get one of these to convert to a scissor style knurling tool. I read article from I think Home Ship Machinist magazine which converted an actual Kant clamp. I tried this, and just managed to ruin the clamp and not get a knurling tool. This kit would be so much easier for the conversion. Thanks for the video. Dave.
Boolean geometry, conic sections and the word topology all in a video about making clamps!... Wow I'm impressed. Just pray that your mill doesn't go all non-Euclidean!
I've been "deburring" the old fashioned way for perhaps fifty years, and I believe I will visit the deburring tools you show to be rather excellent, effective, that I've ignored all the past years. Thanks!
When I was at college taking the Industrial Maintenance Mechanic I had to cut with a hand saw those brackets also using gauges for the radius, a surface grinder, a lathe etc. I was almost done with this project and someone stole it so I had to start all over again.
Right on, Quinn 😊! Doug sent me the same kit. Been sitting on it for a couple months now. Life issues, and needed a few tools but finally got started last night. And being half Ukrainian, I'm going about it a little differently 🤣. Thanks for sharing! Cheers!
I made a set of Kant twist knock offs on my Prototrak . I superglued the sheet stock for the sides to a piece of aluminum plate so I could profile them and do all the drilling in one step. I nested all the sides on one piece of 1/8" x 4" flat bar
I have a question (I'm not a machinist). You mentioned your "dull" tools. Aside from not cutting properly, could such tool mess up the dimensions of a workpiece? I guess piece gets warmer than with a very sharp tool, therefore expands more so that more material is cut off to the final dimensions, right? When it cools down it may be smaller then? Is this a common problem in machining (maybe just in high precision)? Love your videos btw!
One of the biggest challenges with dull tooling is that it leaves a poor surface finish. You are correct about dull tools generating more heat than sharp ones. For many materials such as mild steel it isn't too bad of an issue if you leave the part oversize so that once it cools down you can use a sharp tool to finish it to correct dimensions. Some materials will work harden making them more difficult to perform additional operations. Long story short, it makes sense to keep tools as sharp as possible and, if possible, have identical spares so you don't have to run back and forth sharpening the same tool
When you turn a piece to length, how are you finding the position after putting it back into the collet (or chuck) after measuring? Is touching off accurate enough or is there a better trick? Thanks, Hansi
A woman who likes to live dangerously; handling heated metals while wearing a leather glove with a blown out finger seam. Me doing the same thing: fumble finger one of the parts, and it lands right in the blown seam. Just my life... You know, there's these handy little clamps available in both 3/4" and 1" sizes which would be perfect replacements for the 'paper clips'. I think they're made by... oh, yeah, Kant Twist. ;)~ What makes Kant Twists even better is plastic handle covers; Kant Twist ended up buying the company who makes them. Good combo lathe and mill project to make your own, (hint, hint). Plus, shop made likely won't split like the store bought covers do. Re: the challenge of 'tap too short' There is a specialty tap called an extension tap, (not to be confused with a 'pulley tap' or a 'nut tap', (look up a pic, you'll see what I mean). One type of 'extension tap' has an undercut shank. With an OAL of 4" or 6", and an undercut shank, you can go deep.

Acetone melts super glue,it also if added to super glue can thin super glue or prevent the glue gelling to quickly over time....lasts longer,thins gelled glue,also removes from hair ....but that's another story!!!! i may just feel the need to make some of these clamping devices of various sizes.
Great video Quinn. Good job on keeping the hole in center of the part that was difficult task for the order of operations. You know you are going to have to make a collet stop now. You probably have a piece of scrap that would work. Yould need piece of threaded rod. If you need a sketch of one I can measure the one I use at work.
Great video Quinn, I would love to have this kit. Even more if it was signed! However I’m not brave enough yet to face and drill the side of a cylinder in my 4 jaw chuck. And I don’t have a face plate yet. Can’t wait for the other half of the build. Cheers!
While watching this, I was wondering if cutting a V in the strap of your cross drilling fixture wouldn't give you more purchase on the part you are clamping, or would having clamping force from four faces on a round object actually increase the chance of part slippage rather than decrease it when applying the force of the drilling operation?
Made a set of these years ago that had a maximum jaw opening of about 10 inches or so. Welded the stand-off pins in place. The arms were stainless. Not the best choice as mild steel would probably have been stronger*. Then Enco started selling copies of Kant Twists. I like the ones Stefan uses. The idea of an Acme or Trapezoidal thread is excellent. Even better would be Butress Threads. *I've seen people replace high grade carbon steel screws with stainless thinking they are stronger. They aren't. An M12 SHCS in stainless will have a torque rating in the range of 50 to 60 ftlbs depending on the grade. A grade 12 M12 has a torque rating of 110 ftlbs.
You can get quite wonderful perogies at the Ukrainian East Village Restaurant on 2nd Avenue in NYC. Although it's been a while since I've been there. Requires more recent research.
Interesting project .been considering buying these type clamps but making might be a better option .i think it should just about be with in my capabilities
More than any other tool, any supply, or anything, the woodworker or machinists quest to find or build just "one more clamp" is never satisfied. Clamps are the perfect gift for "the woodworker who has everything". For me to see a stairway maker's project is, I'll become socially awkward, forget myself, and then will need to be excused before I blather on like a bass-boater at a yacht club social.
I made those same clamps in Machining class at tech collage. except we peened over the standoff bushing instead of using screws to hold them. They were a little longer on the small dia. so the could act like a rivet.
Get an old spiral action hand drill (google or ask your grandad), add a small Chuck if needed, use with either internal or external demurring tool - lots easier than your two.
oooh As usual another great video from Blondihacks... but ? they are allways good. let's get a single malt to watch it . bravo et merci pour cette nouvelle vidéo, keep machining .
Quinn, can these be done in a three jaw chuck? that the only one for now that I have for my new lathe and I don't know if the one for the older lathe will adapt to the new one?
This is a really great project! I suppose if one wants to make the plates as well it would be a nightmare to do. All that filling and belt sanding but a great project for semi-experienced people.
Ok, I've got an idea for the straw question. I think maybe you could say that a straw has two holes, or a single bore. This definition treats a hole as a feature that procedes orthogonal to a face in one direction, making a bore a feature that is defined by the meeting of two parallel holes.
I love your honesty and not showing us the rest. Though it wouldn't work temporarily connecting two pieces of steel like you did with super glue, there may be times when hot glue would work to temporarily hold things together. Obviously the material would need to be clean not oily for the glue to hold things together. Hot glue in between two pieces of steel might set up way before the pieces were squished all the way together so that's why it might not work for what you just did. Hot glue will clean off of any surface using 70% or above isopropyl or denatured alcohol. I once "machined" four pieces of quarter inch aluminum plate to make into a router lift. There is a top plate and bottom plate making up the frame. To center sections coupled together hold the router and allow it to move up and down in a sort of carriage. Having a drill press and not a milling machine meant I needed to find an alternative method for accuracy. The center carriage needed to slide up and down on four shafts and not bind. I stacked all four sheets on top of a section of plywood, then carefully "goobered" all four corners together and also onto the plywood. I could then do my layout, punch center holes and drill through all four pieces in one step. There's a fair number of holes and if a hole was off by 1/128ths of an inch.... ... I mean .0078" 😉 It would have made no difference since all holes would be off the exact same amount yet being perfect alignment for what I needed. Iffn' you get bored, try it sometime. I wouldn't want to use that while something spinning it 7500 RPM, but for temporary jigs is really quick and a little squirt from a bottle of your chosen alcohol, the part separate cleanly with no added heat. You squirt the alcohol on the parts let it sit for a few minutes and just try and wiggle and pry them a little bit and they'll pop right apart. That's all about me, so I need to get back and finish watching your video. So far, so good, as I would expect no less .

17:44 wow. I guess I’m in before the straw hole count discussion got going, so I suppose that means it’s up to me? I’ll say 1 hole (not counting any microscopic porosity of the material). :) Who has other answers? Or just wants to discuss this one? We were told to discuss, after all. :)
If a straw has one hole, then how many holes does a sock have (not counting porosity)? If that answer is “zero” then how do you get your foot inside? Purely for discussion purposes of course. : )
@@nbolin2879 I mean, from a mathematical topology standpoint, it is (given the ignoring-porosity proviso) zero. Unless it has a hole in it, of course. And then it’s one! And one gets their foot in the same way we put soup in a bowl. The concavity holds things for us. Well, plus the elastic nature of the material. :)
Dunno.. I don't enjoy a pierogi, but there's a polish restaurant a quarter mile from my house that makes home made chicken pot pie and perogies and the wife says they are pretty epic.

Just make the arms a lot shorter/stiffer. Knurling exerts some serious force into the cross slide as well as the actual tool, not just clamping force.

Can you discuss how you made sure when you flipped the part in the collet block that the feature inside the block was parallel with the vice?
It doesn’t need to be, because they are separate parts. They get cut apart

More than any other tool, any supply, or anything, the woodworker or machinists quest to find or build just "one more clamp" is never satisfied. Clamps are the perfect gift for "the woodworker who has everything".
For me to see a stairway maker's project is, I'll become socially awkward, forget myself, and then will need to be excused before I blather on like a bass-boater at a yacht club social.
This type of clamps are the most useful of them all!
Grat video agan 👍😁
I have come to look forward to your videos. You do great work and give great explainations. Thank you for your effort and hard work.
Cool project. Your description is for an earlier project, lol.
Poopknuckles. I’ll fix it. Thanks for the heads-up
I made those same clamps in Machining class at tech collage. except we peened over the standoff bushing instead of using screws to hold them. They were a little longer on the small dia. so the could act like a rivet.
Straw has no holes. It's a single surface.
5:00 sandblasting would also be an option to get a uniform surface
Get an old spiral action hand drill (google or ask your grandad), add a small Chuck if needed, use with either internal or external demurring tool - lots easier than your two.
Boolean geometry. Love it.
You had me at *"crazy looking hole"* !
oooh As usual another great video from Blondihacks... but ? they are allways good. let's get a single malt to watch it . bravo et merci pour cette nouvelle vidéo, keep machining .
Quinn no Fight you can beat me up.
great Work
Quinn, can these be done in a three jaw chuck? that the only one for now that I have for my new lathe and I don't know if the one for the older lathe will adapt to the new one?
If it repeats reasonably well when flipping parts, I think it could be, yah.
@@Blondihacks my new lathe only has 3thou. riun out at the chuck!
How do you thread from 2 ends and ensure they line up in the middle?
Think about it.
They don’t have to- they are different screws
This is a really great project! I suppose if one wants to make the plates as well it would be a nightmare to do. All that filling and belt sanding but a great project for semi-experienced people.
Agree Quinn re: round hole through round stock. Nerd alert!
great job keep them coming !
I just saw your catshead video, what size inserts does your boring bar take?
Ok, I've got an idea for the straw question. I think maybe you could say that a straw has two holes, or a single bore. This definition treats a hole as a feature that procedes orthogonal to a face in one direction, making a bore a feature that is defined by the meeting of two parallel holes.
Mill scale removal. 25% muriatic acid,25%hydrogen peroxide,50%water, spray on, wait a few minutes, scrub, neutralize and rinse. Super effective
You might do one and know the numbers. I'd have to do a hundred before I started memorizing the numbers
have you ever used an optical center punch?
Great work
I love your honesty and not showing us the rest.
Though it wouldn't work temporarily connecting two pieces of steel like you did with super glue, there may be times when hot glue would work to temporarily hold things together. Obviously the material would need to be clean not oily for the glue to hold things together. Hot glue in between two pieces of steel might set up way before the pieces were squished all the way together so that's why it might not work for what you just did.
Hot glue will clean off of any surface using 70% or above isopropyl or denatured alcohol.
I once "machined" four pieces of quarter inch aluminum plate to make into a router lift. There is a top plate and bottom plate making up the frame. To center sections coupled together hold the router and allow it to move up and down in a sort of carriage.
Having a drill press and not a milling machine meant I needed to find an alternative method for accuracy. The center carriage needed to slide up and down on four shafts and not bind.
I stacked all four sheets on top of a section of plywood, then carefully "goobered" all four corners together and also onto the plywood. I could then do my layout, punch center holes and drill through all four pieces in one step. There's a fair number of holes and if a hole was off by 1/128ths of an inch....
... I mean .0078" 😉
It would have made no difference since all holes would be off the exact same amount yet being perfect alignment for what I needed.
Iffn' you get bored, try it sometime. I wouldn't want to use that while something spinning it 7500 RPM, but for temporary jigs is really quick and a little squirt from a bottle of your chosen alcohol, the part separate cleanly with no added heat. You squirt the alcohol on the parts let it sit for a few minutes and just try and wiggle and pry them a little bit and they'll pop right apart.
That's all about me, so I need to get back and finish watching your video. So far, so good, as I would expect no less
.
So if I get the kit and I am in Texas, how can I even remotely enjoy the newspaper wrapping if its all written in Canadian?
@@ronwilken5219 Sorry Ron, my comment was an attempt at humor. I grew up in Michigan and when I was a young man I would make trips across the boarder often. Drinking age was lower on your side.
@@matthewcarpenter4716 I think Ron's reply was meant to be humor as well. Surly most Texans are literate. ;-)
Now I have to go looking for the first "cross threading" joke!
If you wait for a while they will calm down.
Quinn,
Another fantastic clip, love it.
An the Humour is fantastic, keep up the good work.
A suggestion for another clip, I see you using a magnifying glass from time too time.
How about making an “optical centre punch”?
Cheers Matt.
I had to watch the ending 3 times to work out what was going on with that part, magically launching itself back into place.
In the GD&T world a straw would be a cylinder and they have two holes. So a straw has two holes.
Fantastic Vid. Though we defiantly need more Sprocket. I am saving up for a Precision M Lathe or a Grizzly. Love the Pac Man too. Cheers from Southern California,
How do you read this? 6:33 I get the 0.99 part where did you get the 0,006 from?
17:44 wow. I guess I’m in before the straw hole count discussion got going, so I suppose that means it’s up to me? I’ll say 1 hole (not counting any microscopic porosity of the material). :) Who has other answers? Or just wants to discuss this one? We were told to discuss, after all. :)
@@Neutral_Ground_With_Larkin this makes me angry! For no particular reason! (Except for hoping for humor value.) 🤣
@@DavidLindes Without an Imperial fist shake, I find your anger less than believable. 😏
If a straw has one hole, then how many holes does a sock have (not counting porosity)? If that answer is “zero” then how do you get your foot inside? Purely for discussion purposes of course. : )
@@nbolin2879 I mean, from a mathematical topology standpoint, it is (given the ignoring-porosity proviso) zero. Unless it has a hole in it, of course. And then it’s one! And one gets their foot in the same way we put soup in a bowl. The concavity holds things for us. Well, plus the elastic nature of the material. :)
@@jimmincey2285 Would you believe a metric fist shake?
thank you
, nice review
Nice clamps. I'm surprised they didn't laser cut the holes while they were at it.
Dunno.. I don't enjoy a pierogi, but there's a polish restaurant a quarter mile from my house that makes home made chicken pot pie and perogies and the wife says they are pretty epic. I think the pot pie is very tasty. You're gonna have to fight her though, I think you have at least a 50% chance of winning so no worries.
That is amazing, Quinn! I really want to make these! They seem super useful and I have everything to make them.. Just ordering stock now haha... I found free plans online! Keep up the videos. They are beautifully crafted and they bring me and many others plans and joy. May I ask what that beautiful blackened tap wrench is?
