Introduction: Making a Kant Twist Clamp


Face it, tools are cool! Sometimes tools are so cool that you want them, regardless if they are unavailable to you. Such was the case with the Kant twist clamp. Living in Sweden these clamps are not available, and entirely unheard of, but the desire to have one was still there. Aside from being a useful little tool for many clamping operations, they're also quite an aesthetic tool to have around, and with a little bit of effort, and skill, not too hard to make yourself.

I've made the plans I got inspired by available at the following link, if you plan to use them you may want to adjust the measurements to fit your application: http://switchandlever.com/plans/kant_twist_clamp_plans.pdf

What you will need:

Materials

Sheet metal, for making the arms, preferably a non-flexible steel 1,5 mm thick
Steel rod, for pins, shaft, handle and hinges
Brass, for the gripping blocks/jaws, it's good practice to make them from softer material, so they do not mar what you're clamping
Small screw, for locking shaft in place
Loctite Threadlock, to hold screw and handle in place

Tools

Metal lathe

Milling machine, with suitable endmills and drills
Belt sander, can be replaced by more manual filing
Band saw, can be replaced by hacksaw
Taps and dies, for threading the shaft
Ball peen hammer, for peening the rivets
Files and sandpaper, for refining shape and giving a nice finish to parts
Anvil, or other suitable hard surface to use while riveting


It's not an especially hard project to do, but it does help if you feel at least somewhat comfortable moving around a machine shop, especially so you know enough not to hurt yourself due to ignorance. Anything you may end up doing to yourself as a result of trying to make a clamp like in the video is your sole responsibility, but do be careful and rather think things through once more than do something you're not comfortable with.

Hope you enjoy the video, there will be more to come so stay tuned!

    The store seems to be offline. Is it possible to still buy the plans?

    Store is functional. Go to the link above, even though it results in an error page, hit the store link at top right and get them from there. Cheers!

    The link's dead. Ain't no plan here! I am making one of these twist clamps and I need your help to understand the working of the tool properly.

    Indeed, the link moved. If you go to the store link at top right on that page you can buy the plans from there. Cheers!

    Yep, that is true. I decided as I was putting a lot of time and effort into making these videos and plans, and getting little in return, that I would offer the plans for cheap rather than for free.

    Hmm, it shouldn't be hard to reproduce them from the plans posted, though if you wish I can send you a DXF file with the flat drawings.

    Indeed! John Heisz (of ibuildit.ca) has made one. I had been looking at the Kant twists for a while, but when he made his wooden clamp I got inspired to finally start work on my own metal one. I definitely recommend checking out his videos if you don't know about him.

    Cheers!

    Nice done!
    Thinking of how to convince my headmaster that my 9-12 year old pupils really needs the metal machines...

    Start the lathe, toss them at it, whoever makes it through to the other side graduates as being allowed to use them. Easy!

    I made one just like this 40 years ago when I was an apprentice at apprentice school, I still have it in a toolbox somewhere Nice project

    That's the beauty of home made tools, make them properly and they'll last forever. Can't wait until this gets some patina and dirt on it from use.
