Little project I had last summer. This rail was going over an ares kit so it needed a little material removed. Here are some pics of the lenghthy set up for 25 minutes of milling fun.
Sorry about the clickable pics, photobucket wouldnt let me post large ones. :confused: :rolleyes:


Set up always takes forever. Indicating in fixed jaw of vise.

I laid this rail next to mine for rough dimensions of what needed removed as I have an ares kit on my gun also and both rails go over carbine length gas systems. My rail was considerably shorter though

I had to come up with some kind of fixture to hold the rail in the vise. I bought some 1/2" x 1" stock, milled it perfectly flat and drilled two holes in it that lined up perfectly with the threaded holes in the rail. Two 1/4 20 bolts, washers, nuts and I was ready to go.

I clamped the fixture in the vise and indicated the floor and the sides of the rail.

Finally getting to pull the indicater from the machine and reinserting a 7/16 end mill, I was confident that everything was in order. I could now begin the short (by comparison) process of acually milling the handguard.
I used a magic marker to mark the graduations on my hand feed dial as I didnt have the proper tool it took to measure the distance I was cutting into the sides. It worked just fine. I knew what the ares kit needed to do its job, so I used that number plus alittle. :D

Thats it... I did buy a can of black high temp paint to cover the raw aluminum. I didnt take pictures of that because as usual I just wanted to get the job done. Standing at the machine gives me a back ache. :D

Thanx man... I try. :D
Twas actually my first project for someone other than family or friends. PRO-BONO. :eek:

Just kidding on the "eek", involving payment sometimes makes things complicated and I love the work.
