I am building a rail gun (see links below for more complicated examples than I'm building) and need someone to build three barrel clamps for me.

I have all the measurements except the size of the hole that the barrel goes through. I don't know how large it should be securely clamp the barrel. The rifle is a Ruger 10/22 (.22lr) with a heavy 16.5" bull (.920 muzzle to breech) barrel so recoil is very minimal.

Thank you very much!

Here are the drawings I made up (I am not a machinist):

Here are some way more complicated examples of similar guns:

There is a discussion about this project located here: http://www.cnczone.com/forums/genera...hole_do_i.html

I could machine and hone these clamps in addition to grinding the barrel. If you'd like to incorporate bushings we have the facilities for that as well. What kind of price range and time frame are you looking for? Do you need help with the design work? [email protected]

The vertical dimension is not on your drawing, do you have a dimension for that?

Thanks

Thanks for all the messages and feed back from everyone.

Forgot about height. Updated the drawing: http://thenerdfarm.com/zenpw/Barrel-Clamp.gif

I was thinking aluminum would be acceptable.

I think bushings would be kind of overkill.
