Rail gun question….

[Bodkin84]

My barrel block diameter on my rail gun is to big for my barrel, What material should I make a barrel collar out of so it will fit in my barrel block on my rail gun??? Thanks

How much smaller is your barrel, You can machine the block down so it will c;lamp or you may just be able to take a strip of aluminum and place it on the top of the barrel and then put the block together, It may take a bit of manipulating to get it set right, Split bushing/s out of Delrin/Acetal works good also, Hope that helps....J

Thank you so much! I was hoping you would chime in!!! My barrel is a great deal smaller like a .860 and the block was originally for a 1.5” barrel, so was curious if making split bushings was a option vs machining a new block.

Yeah that's pretty small compared to the 1.450, That would be a pretty thick bushing, However it would still more than likely work. A new block may be the best bet you could also just make a new bottom part of the block and use the top part you already have, Hope that helps....J

Yessir!! Thank you for lending your wisdom! I made a delrin filler block for the top block and bolted my barrel in this evening should see if it works tomorrow! Thanks again
