I made this version of a wooden Kant Twist clamp because Lumberjoe mentioned it which I thought this might be an interesting project. I was able to find complete dimensional drawings online which made it easy to create the 3D CAD model and have it generate the 2D prints for the four arms of the clamp.
My version was made with 1/4” Baltic birch Braces, 5/16” oak dowels for Pins, poplar Handle, laminated Baltic birch Grips, brass Hinges, 1/4” X 20 threaded Shaft, 1/4” X 20 grip bolts/nuts, and a 4×40 setscrew (the Kant Twist terminology in italics).
The Baltic birch Braces have three coats of Deft lacquer, the oak dowels were dyed black and also finished with Deft, while the handle was dyed black and finished with three coats of Zinsser shellac. A 4X40 set screw was used to secure the threaded poplar Handle to the screw Shaft. The entire assembly is press fit together and the button head Allen cap screws hold the Grips.
Testing was done is a less than scientific manner by clamping a bathroom scale. I cranked the handle until the scale read 100 pounds and stopped there as I did not want to reach destructive testing level.
Fun project in that I now have another clamp and as any woodworker knows, you can never have enough clamps!
The following links are for the dimensional drawings I found on line, and link to a folder with more descriptive text of this project, more photographs (5 in total) and two 3D CAD images of the clamp models, and my 2D part prints of this assembly that anyone can use to make their own version(s).
After I completed the assembly and was reviewing the part prints I noticed that I had misinterpreted the web sourced drawings. The smaller leg of Brace A does not have parallel sides so I updated the CAD model, so that anyone can use without the error, but not update the assembled project.
Thanks for looking at this project!
