Small burrs from drilling gas ports

[serevince 0]

I've been using this site as a how to guide to do my conversion. (Thanks, all you pioneers!)

 

I pulled the gas blocks and found 3 holes that were tight on a 1/16 bit when inserted by hand. Possibly good for a 24" barrel, but I am cutting to 18.5" and everything I found said 3 ports at 3/32 was the way to go.

 

So I went! Piece of cake, went slow and followed the original angle.

 

Now I have some small, but sharp burrs in the barrel. Any ideas on removing them?

 

I appreciate the help!

 

So close to being done! Just need to press the barrel off, cut and send it out for threading for rem-chokes.

 

The wait is the hardest part!

 

Thanks

I always go very slowly on a drill press, so I haven't had that issue, but put a bore brush, like a tornado brush on a cleaning rod on your drill & it should clean them up.

 

A 3/32 mill bit would be the key to avoiding that.

If you have a set of small Dremel bits, you could use a ball shaped one if you have one small enough to fit thru the 3/32 hole. Also, sometimes burrs are holding on by a very small amount of metal, and you can shave them off with an exacto knife, you know like a really pointy one that can reach thru the hole.

You can use a small round jewler's file, put it into the port and only file by pulling it back out ( pull direction only ). The smaller the dia of the file, the better.

Given that th bore is hard chrome plated I doubt there is much of a burr

 

Tornado brush or just shoot it.

i used the barrel shaped grindin rocks for a dremel, a little duct tape around the end of the bit and screw it into a cleaning rod. attached it to a drill and run it back and forth over the holes on high speed. Its really low tech and cheap but it worked great for me. i tried a cleaning brush and that just wasnt taking the burrs off.

I just shot them out, very rapidly because I could.

Hello,

 

I reload so I used a wad for a shot shell. It fits the bore to an exact fit.

 

Yes,

It is soft but it grabbed onto the shavings from drilling and pushed them out.

 

Run a shot gun barrel brush wrapped in a patch cut from an old T-shirt. Put several drops of oil on it and run it through the barrel a few times.

 

Make absolutely sure the barrel is clean before you fire that shot gun.

 

Steel shavings will show NO MERCY to your barrel.

 

 

 

Best

Thanks for all the tips! I needed more coffee today, I looked at "bead blast" and was scratching my head for about 5 minutes, before it sank in!

 

That's my current plan is to shoot the heck out of it, and go from there.

 

I did find out today the shop doing my choke will all be at SHOT. I won't get to run this thing until early Feb at the soonest!

 

 

Thanks
