1.5" Piston

Unread postAuthor: Atlantis » Sat Apr 08, 2006 10:18 pm

What's a good material to make a 1.5" piston out of? Yes i've done some research and all that turned up was wax on http://www.advancedspuds.com. I'm going to be using this in a Galfisk ball valve mod piston so I don't need a ruber face.

milk caps make good pistons, just use a bolt, some washers and nuts and some neoprene washers to piece it together

Wood would probably work but it would be hard to shape it right. Wow that was a lot of puns.

Now that was helpful, thank you. Wow, imagine the kind of piston you could make with a 12" Encap.
