Re: SEPA Milling Party?
Just want to point out in case it hasn't been addressed that the milled pocket for the trigger group is mostly relief. Doesn't have to be fancy. You can drill out the bulk of the material and mill the walls clean later. I know people that hacked it out with a drill press and a dremel and the lowers function fine.
Can you post a pic of the mill and set up?

Here it is before putting up onto the bench. I have heard what you are saying before and I'd like to take a look into a factory lower and see what it looks like in there.

Re: SEPA Milling Party?
Hmmm, I see you are using a lathe with a drill press attachment. Not a mill.
It's hard to say without being there, but I would drill out the stock first. An end mill doesn't run well in a drill chuck, if that is the set up. If the end mill is in a collet that would be different.
It's certainly doable. Prints and CAD files are plentiful on the interweb.

Re: SEPA Milling Party?
I tried one with a craftsman drill press.junked it up.The chuck is pressed on so when I tried milling it came off.A drill press with a locked on chuck would probably work.I don't know the name of the system but some drill presses have a chuck that locks in place.A sliding table could perform the cleanup work.

Re: SEPA Milling Party?
Ideally the end mill should be held by a collet. I realize that isn't the case, which is why I would drill as much as stock out as possible, and use the end mill to clean up the remainder. If that's possible with the setup. Not sure how rigid the jig is. Another option may be scribe the pocket profile so you have a visual pattern, if you have the tools to do so. Then you could just grab it securely in the vise and go at
it will the drill press head and take the stock out.
