Feed tube cutting ?'s

Ok I just built a mag from a box of parts. After I mixed and matched and swapped parts. i finally got it shooting. It still chuffs on occasion though, but thats not the problem at hand. What i was wondering was. What is the best method for cutting down the feed tube on a right feed body, and how far. Also is there preffered method for stripping the standard gray finish of the body to polish it or should i just forget that idea.

Thanks

The latest general consensus is using a pipe cutter to take down the feed neck to the desired lenght. Then a little emory cloth or whatever to clean up any burrs. Polishing the body I can't help with.

You should be able to get the pipe cutter at Home Depot or the like. It's a hand held tool that rotates around the pipe.

Here's a picture of one to give you an idea: Lenox 21013-TC258 1/4 to 2-5/8" Tube Cutter You should be able to get a cheaper one than that though.

For Polishing the body, if your going to do it by hand be prepared for a lot of work. The result is worth it though. I did one of my bodies while sitting in front of the TV at night. Took about a week to get it where I wanted it.

Get some Wet/Dry sanding paper, put some cutting oil on it and go to town. Start at a low grit 200 or so and work your way up. I think I went to 900.

take your time, the mag bodies are made of stainless and you will probably go through a couple cutting wheels to get through it.

if you have a bandsaw you will probably have better luck cutting!

I got through pretty easy on one cutting wheel. I couldn't tell you the brand of the grinder though, it was my dads. I do know it was electric(plug, not battery)

I was talking about the wheel on the tubing cutter, a good grinder will work too, but it's harder get it squared up.

I had the easiest time cutting the feed with a bandsaw, the squaring it off with a disc sander, but if all you have is a tubing cutter, buy a couple extra cutting wheels for it.

I cut mine down so the elbow bottomed out on the body, try a few different elbows and make sure you don't cut it too short.

I cut my vertical Highrise down so that I could use a clamping vert elbow on it, and I just used a hacksaw to make the first cut, then a dremel cutting tool to even it out, and then used a dremel grinder to make the top smooth and not have any sharp edges. Works great for me, no longer have to put tape in the feedneck to try and get a hopper to fit.

I am sure a pipe cutter works best, but everyone seems to already have a dremel. Only reason why I made my first cut with a hacksaw is b/c I didn't want to use too many cutting wheels on it.
