90% Glock 34 Gen 3 slide. It’s got that extremely minimalistic aesthetics lol

Here’s the challenge. The slide needs to be final machined and fitted to the barrel.

The locking slot / bolt face needs to be at least .029” wider (cut half that off each side).

The muzzle area hole diameter needs to be at least .010” larger and cannot be done on a lathe.

Why can’t that be done on a lathe? The tilt. I don’t have any adjustments on the lathe that I can make to compensate for the barrel tilt when the gun cycles...

... but damn this is gonna look good.

oh huh the tolerances on a factory Glock are actually not THAT tight. I can totally do this.

Bored the muzzle opening to .590”. Now the .587” barrel barely clears but I’m at my wit’s end on how to do that tilt clearance short of grinding at it with a dremel until it fits...

Welp, chainsaw file vs Stainless slide. I guess it ended up coming down to this afterall...

ALMOST

Victory...

Dovetail time.

Nearly there...

Final hand file and fit.

wow that seriously took like a a whole goddam day... the sights now fit, but I’m not tapping them all the way in place yet because I’m not done with the slide yet

And well, this thing is prolly way too tight the way it is right now, so there’s likely gonna be further finetuning in the near future...

But yeah, this is technically a 100% functional Glock 35 that contains 0% factory Glock parts :P

OK after messing around with this thing for 3 days I need to take it back to the shop.

1) These corners of the dovetails are way too sharp and catch/cut everything they brush up against.

2) The stainless machine finish is way to slippery I can’t rack the damned thing lmao

I’ll need to do a chamfer or fillet the top corners so the corners of the dovetails are not right on the edge.

Then slide serrations will have to be milled, preferably with sandblast afterwards.

Holy shit these fillets took way longer than I expected because it was near impossible to cut 4 IDENTICAL fillets >_>

Anyway, the dovetails don’t bite anymore so I just sandblasted the whole thing and called it a day. Will deal with the slide serrations another time...

Goddammit... Afterthought: Instead of trying to zero off each side at each end and trying to make the same depth cut, I should have just zero'd off ONE side, cut both ends on that ONE side, then flipped the slide 180deg and do the same to the other side.

WHY? This ensures that ANY misalignment and non-orthogonality is preserved, so that if ANYTHING is wrong, it's wrong the SAME WAY everywhere. Instead, I tried to locally minimize the errors and they turned out to all be wrong in their own ways.

WHY did I NOT think of this ARRGHHorz

and also, second-hand smoke headache is |||orzzzz
