This is my version of a clamp knurler.
http://s571.photobucket.com/albums/ss157/chucketn/Machining/knurler/
Its made from a couple pieces of ½ key stock, and ¾ x ¼ flat bar, ½ round stock for the pivots, ¼ all thread, and bolts, nuts, and springs from the junk box. I based it on the clamp knurler drawing available on the LMS website, Thor Hansens design, and Kens plans from Projects in Metal.
The knurl wheels are medium, from LMS.
I started to make the arms from key stock before I had the knurls on hand. I soon realized if I milled a slot in the key stock for a 3/8 thick knurl, the sides holding the knurl would be about 1/16 thick and probably wouldnt hold up. Back to the drawing board!
I actually had to remake several parts as my design evolved, All in all, a fun project. You can imagine my excitement when it worked first try!
I have a ¾ x ¼ straight knurl wheel from the cheepie bump knurl from LMS. I plan to make a plain smooth wheel to match it and try it in my knurler.
