how do I mill a rail for a pump rod?

[knownothingmags]

But.....how does anyone ever learn to do anything without asking the questions? I'm sure there was a time when Luke and everyone else didn't know how to mill a rail. Someone had to teach them. They had to learn. I want to do that too.

And don't worry. If I botch it up, I promise I won't send it to you for fixing. I'll just ULE the rail and sell it for a profit.

I have plenty of extra rails for you too if you need more practice. And of the metal variety. [emoji16]. If you want to learn, learn. And no worries back when I was buying I came across mucho rails [emoji16] hit me up if you need another.

That's a bit harsh, Jake. Let the man (or woman, or whatever they identify as) live their life. Aren't screw ups half the fun?

The fact that you are even asking the question means you shouldn't do it. It is not a straight cut. Last thing i want is another botched pumpmag rail that myself or someone else needs to try and fix. Save yourself, the next guy and the next guy the trouble and send it to luke. I send everyone to luke for the pump milling because he is set up for it and its correct.




I agree with this.

Manual mill with an angle vice it's an easy job but don't rush it, Cnc is obviously easier :)

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...

Who said it cant be done on a manual mill?

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

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.

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).

Just machine a fixture.
