AutoCocker Valve/Hammer dimensions

Hey, 'Nation!
I'm doing a final project for metal shop and I figured I'd use the mill and lathe at school to make a valve and hammer for my AutoCocker build. The materials and machining isn't a problem, it's just the issues of having the dimensions of the valve and hammer for a standard AutoCocker. I don't have one I can measure and I was wondering if there were any published anywhere or if someone with a spare and some calipers could give me some dimensions for it!
Thanks in advance, guys!
Noah

Awesome! Just what I needed! You're my hero! I'll make something similar to this, maybe just tweaked a little, but the same dimensions. Awesome!
These are in inches, correct?

All right, I've got .sldprt, .slddrw, and E-Drawing files that I'll put up shortly. I've made some nice drawings, so we're good!
Thanks for your help, I'm still looking for hammer dimensions...

May I direct you here for some thread tapping info.

http://www.pbnation.com/showthread.php?t=803907

And here for hammer info.

http://customcockers.com/forum/showt...ck-hammer-info

*WARNING* I am not sure of the accuracy of these dimensions so use at your own risk.

I may get my friend to make new a new hammer and valve instead of buying them so let me know how it works out!

The hammer is for a half-block, it doesn't give dimensions for the overall hammer...sorry! I need really rough measurements, I can deduce the rest from lower tube sizes and stuff like that, just need some spacing things, cut lengths, and a few other things.
Thanks anyways!

what do you need from a hammer? I can get you pretty much anything save the half block slot length...

I can also get my buddy to take precise measurements on my hammer before he modifies it, if you still need numbers. He's a professional machinist so the measurements would be accurate.

Its ugly but it was quick. Also I think the lug may actually be a 1/4-30 but that's not UN so I picked the closest UN thread. Also it doesnt really matter if you're making your own anyway

Thanks!
I was actually able to snag the dimensions from the AutoCocker owner's group on Facebook. I need to upload my .slddwg file I made of it...it might simplify things.
The thread ended up being 1/4-28 for the timing lug and the OD was .679."
I whipped it up on the lathe at school out of a piece of scrap SAE1018, and so far it works like a charm!
Thanks for all the help, guys, I now have a valve and hammer! I just need to figure out how to make hexagonal holes for the jam nut and IVG...
