Racepres Posted January 3, 2022 Report Share Posted January 3, 2022 Anyone have a home shop method to chase the internal "buttress" thread inside of a Small Ring Bolt?? Acquired one from a friend that was probably misheated... when modifying the bolt.. the Shroud will Not screw in... None around here will!!! Or... I will cut the handle off (it is a decent store bought example).. and toss the bolt I guess!!! Thanks Quote Link to comment Share on other sites More sharing options...
Horsefly Posted January 3, 2022 Report Share Posted January 3, 2022 What about a spare shroud with fine valve grinding compound. Works on barrels and sometimes you think no way. Just paint some on threads and start twisting in and out by hand. I have a thread chaser but can’t remember large or small ring I’ll look in a bit and let you know. If shroud won’t even try to start, think I’d be looking for another bolt. That’s a lot of heat. Quote Link to comment Share on other sites More sharing options...
Horsefly Posted January 3, 2022 Report Share Posted January 3, 2022 I have this and it screws into 93 bolt. Had it over 30 years and don’t remember what I bought it for. Let me know if you want me to send it. Looks like a thread chaser to me. Quote Link to comment Share on other sites More sharing options...

But, if it looks like it will chase threads.. I would love to try it.. I would try the Valve grinding compound, (like with a Barrel) but.. I would only do that with one that they were gonna stay mated to.. if it cleans up...then maybe another shroud.. It does start... goes a ways then gets exceedingly Tight!! Drop me a PM with Cost of Shipping... I believe you gots the address...But... LMK Thanks.. Quote Link to comment Share on other sites More sharing options...
Horsefly Posted January 3, 2022 Report Share Posted January 3, 2022 Sorry about no pic. I forgot ! Quote Link to comment Share on other sites More sharing options...
Racepres Posted January 3, 2022 Author Report Share Posted January 3, 2022 ^^ that is a heat synch for bolt welding or modifying... I do Not feel it should be used for thread chasing. Quote Link to comment Share on other sites More sharing options...
Racepres Posted January 3, 2022 Author Report Share Posted January 3, 2022 I will maybe source another shroud and go with valve grind compound!! Have access to Lathe, maybe should whittle something out??? Quote Link to comment Share on other sites More sharing options...
Horsefly Posted January 4, 2022 Report Share Posted January 4, 2022 I thought it might be a heat sink but way way different than the one I have for 98’s. I put a file on it snd is soft. Sorry ! Quote Link to comment Share on other sites More sharing options...
