M40scoutsniper Posted January 15 Report Share Posted January 15 Good evening everyone! Hope everyone in the forum is staying warm as we’ve got -7° temps goin on out here in Kansas. So Deerslayer has been doing a project for me after he put his magic touch on a semi M1 Thompson clone. After some talking we decided to do a 21AC semi clone as well. Unfortunately as many of us know Kahr is no longer offering the round knurled ball cocking handle. All they offer is that large barrel shaped knurled cocking handle that some refer to as the “cheese grater”. Now the project is coming to a close and Deerslayer did an awesome job reshaping one of those “cheese grater” cocking handles. I just wanna put out some feelers though and see if anyone possibly has an extra knurled ball cocking handle that they would be willing part with. Below is the part I am looking for. Below is a few pics of my M1 and the 21AC being completed so far! Deerslayer, if you read this thank you for all of your hard work! Link to comment Share on other sites More sharing options...
peter kohler Posted January 16 Report Share Posted January 16 very nice work Link to comment Share on other sites More sharing options...
deerslayer Posted January 17 Report Share Posted January 17 Nice picture! My earlier attempt at reshaping a knob on the lathe didnt work, but spinning one against the belt sander did. Mark 1 eyeball and a steady hand once again show whats possible. 1 Link to comment Share on other sites More sharing options...
68coupe Posted January 18 Report Share Posted January 18 (edited) I'm gonna have to look this up, but I vaguely recall that someone on this forum was offering to make some, start to finish. Then again, I've been known to be wrong, quite often. There was someone else making receiver vices & barrel wrenches more than a year ago. Of that, I am sure. I got a set, which work quite nicely. My only issue was the nuts on the wrench need to be grade 8, instead of whatever they were out-of-the-box. Karl, 68coupe Edit: I did a search. It seems the machinist that was making them has passed.

laurencen Posted January 18 Report Share Posted January 18 the ball is the easy part if you grind a form tool, you would have to knurl before the slot was cut, made a few over the years for display 1 Link to comment Share on other sites More sharing options...
DARIVS Posted January 18 Report Share Posted January 18 I reshaped my handle into a ball years ago, but still have to put it into the lathe and knurling with the knurling tool. It's been waiting for 24 years to get 10 minutes work to finish this last detail off. Typical project. 1 Link to comment Share on other sites More sharing options...
M40scoutsniper Posted January 23 Author Report Share Posted January 23 I just contacted Kahr this morning concerning the part and got a hold of a fella in the service department. He told me they stopped producing those cocking knobs about 2 years ago. I also asked about NOS or dead stock parts and was told they didn’t have any. So I reached out to Ravenna Armory about making some. They responded by saying they weren’t really interested in producing them, but check with Indianapolis Ordnance. I’m waiting to hear back from Indianapolis Ordnance now. I feel like a historically accurate aftermarket cocking knob would be pretty popular among the semi Thompson community. 1 Link to comment Share on other sites More sharing options...
Motorcar Posted January 25 Report Share Posted January 25 Here is an old thread on the same subject, picture of a cheese grater I had turned down to correct spec, just didn't have the knurling done. Link to comment Share on other sites More sharing options...

Did you happen to ask why they replaced a popular part with an ugly one? Link to comment Share on other sites More sharing options...

M40scoutsniper Posted January 27 Author Report Share Posted January 27 No… I didn’t even think to ask!🤦🏻♂️. I think we’re on to something with Indianapolis Ordnance though! They sent me a photo… 😬 Link to comment Share on other sites More sharing options...
