Needed to make a short knurled shaft to hold some nylon cams for a gate operator that I am building. I've need a knurler for some time an saw a post of a gentleman that constructed one from a 2" kant twist clamp so here is my version. Purchased some 3/4 od * .25 bore * .369 knurling wheels and a 2" kant twist clamp.

removed the rivets from the shoes and pivot point. drilled the pivot to .3125 and the holes for the shoes to a #12



Made 2 bushings to reduce the knurl bore to .1875 from .25 drill rod, one spacer for the main pivot point out of .75 x .324 x .3125 bore out of 1018 and two spacers for one knurl .5 x .190 x .190 bore, out of .5 drill rod
Drilled through a piece of .5 key stock with a F drill, counter-bored to .3125 and a depth of .370, tapped remaining hole to .25 x 20 Hardware. one 1.25- .3125 SHSC, two .3125 SAE washers, one .25 nut, two # 10-32 SHCS cut to 1.115 in length, 4 # 10 SAE washers, two 10-32 nylon locking nuts.





Tool worked just fine, knurl turned out great for my first time. I was a little concerned about the rigidity of this as the clamp joints are quite loose "good for a clamp, bad for a knurler" but once you assemble it it is surprisingly rigid and moves very little when the carriage travels.

That is a very neat idea. I have been wanting to build a clamp type knurler, but I never thought of re-purposing a can't twist for that

That's ingenuity at its finest.

Cool.

 

[Ed ke6bnl]

was wondering also that if you were to weld in plates in the open spaces if that would make it more stable??

Great idea, I would have never thought of it.
