chp5 Posted March 21, 2006 Share Posted March 21, 2006 I want to polish the chamber of my 9mm XD. I assume I should use the Dremel and some Flitz - is that correct? What Dremel attachment do I need? Any other advice . . Thanks. Link to comment Share on other sites More sharing options...
Jon Merricks Posted March 21, 2006 Share Posted March 21, 2006 I use JB bore stuff. I found a round hard cloth peice that fit 9mm perfect, it came in a little multi pack from Lowe's. Link to comment Share on other sites More sharing options...
Canuck-IL Posted March 21, 2006 Share Posted March 21, 2006 For my edification...why would you want a polished chamber? The casing needs some friction against the walls to assure a positive seal. To me, as long as feeding is reliable, the chamber should be kept clean but not polished....??? /Bryan Link to comment Share on other sites More sharing options...
ima45dv8 Posted March 21, 2006 Share Posted March 21, 2006 It seals by expanding during ignition. The brass has enough "flex" to seal even against a chamber with a very smooth finish. In fact that may cause even better contact. The breechface prevents readward movement so the seal is pretty effective. If you look at fired cases from light, poofy loads they tend have soot down one side from because there wasn't enough pressure to fully swell the brass in the chamber. After the round has fired the smooth finish of course aides in in extraction. Link to comment Share on other sites More sharing options...
Precision40 Posted March 21, 2006 Share Posted March 21, 2006 I was able to find a small, Dremel buffing wheel at Walmart which was a VERY close fit to my G34 chamber. That wheel also works perfect on the feed ramp as well. Link to comment Share on other sites More sharing options...
Harmon Posted March 21, 2006 Share Posted March 21, 2006 again why polish a chamber?? i dont think it would be advisable unless you had a really ROUGH chamber that when you fired a round, the extractor could not reliably pull the fired round from the chamber.. if the gun is chambering ammo and ejecting fired brass normally, why tinker? if someone can think of a good reason to polish the chamber (other than they want something to do) please tell me.

TMC Posted March 21, 2006 Share Posted March 21, 2006 again why polish a chamber??Harmon Like it has been said, a polished chamber will make sealing better, aid in extraction, less crap will get built up because most stuff doesn't stick well to a polished surface. A gun is a small machine and anywhere parts move aginst each other, including the ammo, polished surfaces will make it run and smoother. Link to comment Share on other sites More sharing options...
Loves2Shoot Posted March 21, 2006 Share Posted March 21, 2006 I can feel when my chamber gets dirty and it time to polish it up again when I shoot. That's enough reason for me to polish. Link to comment Share on other sites More sharing options...
L9X25 Posted March 21, 2006 Share Posted March 21, 2006 (edited) Most gunsmiths will readily agree that the exractor is one of the most stressed, and likely to fail, items in your gun (particularly in a 1911 style gun). Anything that can make the extractors job easier is a good idea. Edited March 21, 2006 by L9X25 Link to comment Share on other sites More sharing options...
j2fast Posted March 21, 2006 Share Posted March 21, 2006 For my edification...why would you want a polished chamber? /Bryan again why polish a chamber??Harmon I believe he posted in another thread that he was having FTE's in his new to him HS/XD.

I think he just looking to remedy that situation but don't quote me..... A polished chamber helps in the extraction of aluminium cases. (Blazer) Flitz on a Dremel bob works well.

Jon Merricks Posted March 21, 2006 Share Posted March 21, 2006 I'm trying to figure out why some of you are asking and answering your own question,,,at the same time. Link to comment Share on other sites More sharing options...
Flexmoney Posted March 21, 2006 Share Posted March 21, 2006 If I had a gun that needed the chamber polished, I'd send it back. I am pretty handy with the dremel, and i don't want to go sticking one into the chamber. Link to comment Share on other sites More sharing options...
Bob Hostetter Posted March 21, 2006 Share Posted March 21, 2006 Actually a polished chamber will aid in both feeding and extraction. The thing you want to watch is making sure you are just polishing the chamber and not removing a lot of material. A very soft cloth wheel will work as long as its not overly large. Toothpaste is a good polishing compound. Make sure you keep the wheel moving back and forth, don't let it sit in one place. And remember a little bit is good, too much can be bad........

I think he just looking to remedy that situation but don't quote me..... That's it! I'm having about a 1-2% failures to extract with my HS2000 (a/k/a XD). I swapped out a new extractor from a buddy's XD and still have FTEs. The chamber looks fairly rough, with visible rings in the chamber. I started polishing tonight with some Flitz and a bullet-shaped felt Dremel attachment. The felt bullet sometimes comes off the rod. I need to get another one to finish the job. I hope this helps . . . Thanks for the replies. Any other advice? Is there a better attachment to use? Thanks, Cy Link to comment Share on other sites More sharing options...
chp5 Posted March 22, 2006 Author Share Posted March 22, 2006 UPDATE I polished the chamber last night and shoot about 320 rounds through the HS2000 this AM. The rounds were a combo of my reloads and Rem 115's. I had zero failures to extract! (knock on wood) I still need to find a better felt attachement for the Dremel for polishing. Any other recommendations? Link to comment Share on other sites More sharing options...
XRe Posted March 22, 2006 Share Posted March 22, 2006 Cy, I used one of these Dremel 414 felt wheels. I attached it to the Dremel, and then held it against a sharp edge on my vise jaw to "whittle" it down to just under the size of the chamber. At 35K RPM, it shrinks down pretty quick. Seemed to work like a champ. Link to comment Share on other sites More sharing options...
.40AET Posted March 22, 2006 Share Posted March 22, 2006 Dremel felt cylinder These worked great on my .40 Para. It cleaned up the chamber real well. That and a little ramp work and the gun ran great. You can get the little felt cylinders at Home Depot and Lowes in the dremel section. Link to comment Share on other sites More sharing options...

bountyhunter Posted March 22, 2006 Share Posted March 22, 2006 I was able to find a small, Dremel buffing wheel at Walmart which was a VERY close fit to my G34 chamber. That wheel also works perfect on the feed ramp as well. I have a theory about Dremels: they are fine gunsmithing tools as long as you put them in the closet and set a bowling ball on top of them before you begin working on any gun. I assume you mean the throat of an auto loader's barrel? I agree that polishing is only needed if you have feeding problems. I polish throats using #400, #600, #800 grit sandpaper (and oil) wrapped around the smooth end of a drill bit whose size is perfect to fit the thraot of that particular caliber. Sand by hand usuing and in-and-out motion. I sometimes finish polish with a patch wrapped around a drill shank using chrome polish but that is just for looks..... making it mirror shiny does nothing to improve function. Looks pretty..... again, hand polish in-and-out motion also on the feed ramp. Link to comment Share on other sites More sharing options...
chp5 Posted April 3, 2006 Author Share Posted April 3, 2006 About 600 rounds later - I've had no FTE's (knock on wood). Thanks to those who posted advice. Link to comment Share on other sites More sharing options...
