Also click to biggify and you can see the tool paths in the block.

I always wondered how weird profiles like that got machined, neat! Would something like this be possible without CNC?

... roughing @ 2,500 SFM?! what the fuuuuuuuuuuuuuuuck



for non-machinists Surface Feet per Minute is how fast the blade/cutter is passing the work, like how fast a needle might be traveling on a record, etc. Most steels and stainless steels are somewhere between like, 50-120 sfm, aluminum 300++ sfm...

2.5k, JESUS CHRIST

I'm pretty sure even a warm knife through butter can't go that fast.

oh well... had to attempt to spread the 9x39 bug

Might be an easier sell if you make an effort post as to what else is required in terms of gun/parts/tools/skills.

Too much work, just open the hole up progressively with number drill bits until it runs, if you make it too big then that just means you now get to create/incorporate an adjustable gas block to your design

I kind of ruled out stepping up the sized a little bit at a time because that would require pressing pins in and out to remove the gas block each time

Could just make a second gas block with a large threaded hole on the top to give you access to the port. Once you find the right size hole then swap in the final GB.
