Low Profile Mill Clamps

[@FrancisoDoncona]

Question, are those free cap screws digging into the t slot bottom? Aren’t the t slot bottoms irregular, not machined? Won’t they get chewed up as cast is softer than steel? Just asking because I think I am going to add a washer or t cover to mine.

[@TomMakeHere]

Yes, I flattened the tip to prevent damage. Also I don't tighten them crazy hard, there is a risk that the jacking action could break the T-slot. I've allowed provision for a top clamping plate if required

[@Stephen8454]

I can seriously watch this all day.

It's a nice chuck, I just wish I had the outer jaws to go with it

[@carramba86h77]

Tip: don’t put the brush back in de bottle after you used it on blueing metal. Just pour a little blueing liquid an a plate or something.

[@ebayollis]

Not arguing with you, but may I ask why?

[@patrickd9551]

@@ebayollis during blueing oxides form, which you partially rub off the metal onto the brush and then contaminating the blueing solution. In essence you put a small portion of rust back into the bottle of blue. Mind you it's only small quantities and it's basically just sloppy work, personally I doubt that it will pose any real risk of real degradation. It'll probably function just fine for 99% of the jobs.

[@kentuckytrapper780]

Hell I dip my part's in a five gallon bucket of blue, it's five years old still does a excellent job.

[@tomb816]

@@kentuckytrapper780 Yeah, I just dunk the parts into the container. Been using the same container for a while now. You'll see some bits(prob iron oxide) in the bottom, but I just pour it through a strainer to remove them.

[@ALSomthin]

Hey before you remove your chuck from the lathe spindle next time chuck up a rod of cold roll close to the size if the spindle bore in the jaws that extends into the spindle bore 6 " and sticks out of the chuck jaws 6" on the face side. The bar will then act as an insertion guide on one end and line up the threads on the chuck adapter and act as a handle on the other side. This makes taking the chuck off and putting the chuck back on real easy and avoids thread damage.

[@TomMakeHere]

Good tip. Cheers

@@TomMakeHere I wondered what was going on there as well !

[@tcratius1748]

Out of curiosity, why did you do that?

[@TomMakeHere]

@@tcratius1748 Do what? Turn the bolt eccentric? This makes the the action of turning screw allow it to cam against the hex shape and exert a sidewards pressure on the work piece. The whole tool is a compact cam clamp

[@xConundrumx]

Do you have a love/hate relationship with that vice too? The mechanism on the bottom that locks it different hooks for different widths is so iffy sometimes.

[@TomMakeHere]

Yes, I've now upgraded to an 'anglock' style vice. Much more reliable for milling

[@xConundrumx]

@@TomMakeHere Bit too high for me those, it's just a desktop cnc machine not a full on mill.

[@TomMakeHere]

@@xConundrumx yep, height is always an issue. A 2 piece vice might be worth looking into too

[@xConundrumx]

@@TomMakeHere My thinking too, maybe not a vise in the classical sense though. Something modular maybe. Haven't quite figured it out yet. Vacuum holding is another option I am exploring.

[@troyam6607]

Editing on point 👌 i wont lie, when you put that part in to test the way it was aimed on the rotational force i was waiting for it to go shooting out haha

[@TomMakeHere]

You need to get a 'grip'!

[@troyam6607]

@@TomMakeHere just had a thought because the bolt heads are only using friction to hold the nut against the work piece if you use a smooth sided piece just be careful if your drilling it doesn't lift up, as there is nothing holding the nuts to the T nut

[@TomMakeHere]

@@troyam6607 yep good point. I think generally I'll use this for surface milling, but in that case I'd probably put a strap clamp on it. I'll just need to remember not to drill my mill table lol

[@pgs8597]

G’day Tommy, simple yet effective, well done. Cheers Peter

[@TomMakeHere]

Cheers👍

[@NathanNostaw]

Am I correct in assuming the clamping force is from the 'tipping' of the T nut by the rear cap head screw? So, push the hex as hard as you can to the job, lightly tighten the rear cap head, then tighten the hex cap head, then repeat to all of them, then tighten the rear cap heads to gain clapping force? If so, very neat and I want some.

[@TomMakeHere]

Yeah so it is the cam action of the eccentric cap screw that pushes the hex against the work, after the rear screw has locked it in place The rear screw is ok, but could damage a mill table if tightened hard. Ideally there would be top and bottom clamping plates. I might make this change They are very useful

[@GoCreatehms]

I like those,surprisingly effective! Looks like another job to add to my todo list. Cheers!

[@TomMakeHere]

Yeah, it's better than I expected! Definately going to be a good thing

[@robertfontaine3650]

Just enjoying the process. Do you use machine oil or way oil on the clamp heads?

[@TomMakeHere]

I think I used a light spindle oil from memory. It doesn't matter too much, you just want oil to soak into the blued steel

[@KenzoAkihiro]

What liquid do you use (the blue bottle), what type is it called?

[@TomMakeHere]

It is a cold blue solution. The chemical is usually Selenium Dioxide for steel. It adds a black oxide layer with pitting which allows oil impregnation to prevent rust

[@KenzoAkihiro]

[@젠스-v7x]

I am a Korean MCT engineer. Is it necessary to do so? You can put an aluminum plate on top and tap it to make it easier

[@TomMakeHere]

There are many ways of completing any task. These are just another option They are best suited to milling the entire surface of a plate where you cannot have clamps on top as they are in the way of the milling operation

[@CraigsWorkshop]

My second comment: I just noticed another commenter talking about whether the bluing stuff was available in Aus. You're using Birchwood Casey brand in the video, which I can get locally in Hobart (Moonah fishing/hunting place). If you want more Tom, let me know and I can get some and forward it to you.

[@gworx-247]

well done! thank you 👍

[@LetsRogerThat]

Thanks Tom. I’m trying to mill 8” sine plates and having a bitch of a time. Vise/fail, clamping/fail due to multiple clamping changes. This I hope will work. Tks. Gilles 🇨🇦

[@Joe_Bandit]

Nice! I'm going to have a shot at this. How much bigger is the hole in the hex nut than the cap screw head?

[@TomMakeHere]

Maybe 0.5 to 1 mm clearance should be fine. The most important thing is the cap screw head must be eccentric. Mine was maybe 1 mm eccentric As an improvement on this design, I would have a plate on the rear cap screw so the plate is pulled down onto the table and the T nut pulled up. If that makes sense

[@Joe_Bandit]

@@TomMakeHere makes sense, much appreciated!

[@ke6bnl]

I guess they could be made as a two piece. One Eccentric and one hold down

[@TomMakeHere]

Absolutely 2 would work fine, but 4 will allow clamping of very unusual shapes

[@dziggy3004]

impressive. the heads of the cap screws seemed to be turned off-center (wobbly in chuck). is that by design? to create a partial cam-effect?

[@TomMakeHere]

100% correct. It is the cam action of the screw head holding the part

@dumpy4289 to be honest, it was a guess based on what seemed reasonable and didn't destroy the screw head. If it didn't work I would have tried something else

Cheers Craig. Yes I thought it was about time to get around to it I'm forever holding big flat plates and it's becoming a problem

[@CraigsWorkshop]

@@TomMakeHere yeah, machining the entire face of a plate is a pretty common use case. Surprised these clamps aren't more common. I suppose the large 2 piece style mill vise (ToT style) could be used with parallels too, for plate surfacing, but this sort is much cheaper and easier to build.

[@TomMakeHere]

​@@CraigsWorkshop Yeah I decided to go simple. At some point I will make up 2 precision rails to go with these for repeat plate work (so I can make an inside corner to butt a plate against)

[@jeremyshalala6843]

Nice mate! I know I saw a comment about this already, but thought I would just reinforce the idea that using the cap screw to push it up from the bottom of the t slot isnt the best idea. Not only can you damage the tslots, but you're drastically reducing the clamping potential because of the lack of surface area on the bottomed out screw. T slots are meant to be clamped in compression 😊 if how you have it works for what you need then awesome, but just something to keep in mind. Maybe consider custom washers with csk screws for the future to retain that low profile.

[@TomMakeHere]

Yep, I've allowed space on the T nut for this purpose All of the commercial designs run like this so I thought I would try this first and upgrade if required

[@Moronicsmurf]

Clamps the bolt with the ER collet.. out of round completely.. zero fucks given.. my man! :D
