how do I mill a rail for a pump rod?

[luke]

Here's how I set up to machine my fixture.

Tram your vise.
Square your material in your vise with machinist square.
Set the proper angle.
Machine top of material.
Drill and tap your holes to AGD rail spec.
Machine the rail bushing hole.

*I drill and tap my holes on the fixture with my work offset coordinates in mind (XYZ-Zero) so I can setup the job off the fixture instead of off the rail being machined.

So which route did you go, angle vise of fixture?

I haven't gotten around to it yet, sadly. Hopefully this will happen in the next week or so. But I don't have an angle vise, so I'm probably gonna try the fixture.

To pump mill....I use my teeth, a butter knife and an oring pic...but I'm old school.....LOL!
The I send it to Luke to fix...and buy new dentures...

[luke]

Yes.

[rawbutter]

That's clever. It holds the rail at an angle for the channel cut, right?

I've used this fixture on my knee mill and cnc.

rainman did not machine to agd spec.

I know. But Luke did.
And that's one of the earlier rainman kits which does seem to be close enough (and works much smoother than AGD original I got).

Should be, at least close enough. Friend of mine made few rails for me and himself with that as reference.
It's been tested with rainman's older pump kit on a rail milled with that reference and on a rail that Luke milled to spec (and which it is currently using).

I just need to find an angle vice first.

Just machine a fixture.

That's great. Cougar20th sent me the same thing, so I think I'm good to attempt something. I just need to find an angle vice first.

Here's what I've saved from haveblue.org, since it seems to have died.

OMG, how did people ever mill anything in the 200+ years of metal working without the aid of computers???

Just forget it. It can never, ever be done manually. Forget that you can take the time to make it a compound cut, because it is just a straight slot, with a ramp up. Come on, a pump slot is shear rocket science and no one has ever gone into space, put a man (men) on the moon, or even gone great & vast distances without a computer. Call the boys and girls at Nasa, the Jet Propulsion laboratory, MIT, cause that **** is way to difficult to ever be figured out. Seriously...

I <3 this. Welcome to the party!
