zdog Posted January 17, 2011 Share Posted January 17, 2011 Hi Folks, Anyone know of someone in the Phoenix area who can polish the forcing cone on my 625-8? Thanks, Zdog Link to comment Share on other sites More sharing options...

Carmoney Posted January 25, 2011 Share Posted January 25, 2011 No, seriously, I'm curious.....why would a forcing cone need polished? Link to comment Share on other sites More sharing options...

gr7070 Posted January 25, 2011 Share Posted January 25, 2011 (edited) No, seriously, I'm curious.....why would a forcing cone need polished? I wouldn't want to use any (significant) abrasive on the forcing cone and change the gap, or the angle between the forcing cone and the cylinder face, or round the edges on the barrel, etc. that polishing might introduce. Clean with a brush and solvent and that should be good enough. Edited January 25, 2011 by gr7070 Link to comment Share on other sites More sharing options...
Carmoney Posted January 25, 2011 Share Posted January 25, 2011 I do know that when Cliff wanders around Las Vegas at night looking for someone to "polish his forcing cone," it's a whole different thing altogether. Link to comment Share on other sites More sharing options...

Clean with a brush and solvent and that should be good enough. Use a high quality brush and one of the K-Y polishing compounds and finish it off with some patchouli oil.

z40acp Posted January 25, 2011 Share Posted January 25, 2011 (edited) Brownells used to sell a kit with the different cutters and they also had a brass cone that you could put polishing compound on. I recut a 629 for a 11 degree forcing cone. The factory cone was pretty rough but the cutter made it smooth and I never used the brass attachment. It helped tighten the groups with lead bullets.

Said that it would nearly always tighten up your groups. Never tried it myself but a gun rag can't be wrong..... Link to comment Share on other sites More sharing options...

Probably not called polishing but lapping, But neither one is safe from the double entendre crowd. I got my kit that z40acp speaks of from Brownell's.

granderojo Posted January 26, 2011 Share Posted January 26, 2011 Seems like I saw a pic that was posted here not long (I think it was a thread about cyl chamfer, maybe) on one of JM's guns that was done by Clark Custom and the cone had a serious shin in it. I don't know about improving accuracy, but it would have to increase speed and raise the PF for the same load, No? Link to comment Share on other sites More sharing options...

Glad folks are having some fun..... The forcing cone on my 625-8 had concentric machine marks. Since I was having lead build up in the forcing cone and not the barrel I decided it wouldn't hurt to polish those marks out. I have learned that you can buy the tools to do this at Brownells for not much money if you don't buy the cutters. I had to ask around to find what the angle was on the 625-8. Some said 11 degrees...some said 18 degrees. Have to know that to buy the right brass tool. I finally sent an email to S&W since I got two different answers from their phone guys. The official answer is 15 to 18 degrees. Can the forcing cone angle be cut down? I hear that a 11 degree is likely to be more accurate.

z40acp Posted February 17, 2011 Share Posted February 17, 2011 You should wait for an opinion of a real Gunsmith but you probably could recut it to 11 degrees. My 629 had a small forcing cone gap and I opened it up to .005" because I was shooting bowling pins with it and it would freeze up. After I did the forcing cone and polished the bore it improved the lead bullet accuracy. Link to comment Share on other sites More sharing options...
Toolguy Posted February 17, 2011 Share Posted February 17, 2011 (edited) I use the 11 degree kit from Brownell's for all my guns. There is no magic forcing cone angle, the same as there is no magic muzzle crown angle. What really matters is that it is smooth and concentric to the bore. For the forcing cone you want it not too big and not too small. There are gages for that but it's not real critical to have a certain exact size. If you smooth it out with the 11 degree cutter just till it cleans up you will be fine. Edited February 17, 2011 by Toolguy Link to comment Share on other sites More sharing options...
