I was thinking of playing around with a Sarco $50 slide on a bridgeport at work. I figure I can do some new sights, dress the sides and I would like to lower the ejection port.
I just need to know how much material to cut (or leave)
Even though those slides are only $50, they are forged and are tough as nails. I dressd mine off on a surface grinder to remove the Argentine markings. Then I recut the cocking serrations (thanks for the info on your page Blindhogg). I used a carbide endmill, and it still left some burrs. When I tried to just bend the burrs back and forth to remove them, they were really tough and hard.
My slide is somewhat loose on the Auto-Ordinance frame that I did manage to put a ramp spacer into (it turned out much better than I had even hoped for). I tried to squeeze the slide tighter in the vise on my milling machine, but wow, no go. I'm afraid that I'll spring my vise. Maybe if I only squeeze a small portion at a time stating at the rear, I'll have better results.

I need to write a article on how I do this in my shop for my website, but I do it like this. First clamp your slide sideways, I use the Yavapi slide holder but you can be creative if you like and get by without it. Next chuck a 3/8 carbide mill bit turning 1100RPM and start hogging and lowering ejection port until the bottom of the ejection port is .450 from the bottom of the slide.
Good luck, with a carbide bit you should have no problem working on any slide
