Aluminum Extrusion for Barrel Material

Unread postAuthor: hwmetzger » Tue Nov 21, 2017 8:09 pm

Hello guys, first post here!

I was recently given some heavy aluminum extrusions that I thought would make a fantastic barrel for a higher pressure spud gun. Theyre a 2.5" unequal hex extrusion, 1.75" bore and 10ft long. I believe they're 6063-T6, the thinnest point (between bore and wall) is 3/8", making for a heavy wall at the thinnest point.

My initial thought was a hybrid gun. Any ideas on what sort of pressure I could safely use? And any suggestions for general build style here? I'd hate to use these for a run of the mill gun :D

Welcome to the forum!

Burst pressure for that should be around 7000 psi, meaning a high-mix hybrid would definitely be a possibility.

You know what would be awesome, a Wall Gun style launcher.

The octagonal profile of the barrel would really lend itself to the look.

I would want to build a Golden Boy from one, or a BASR. 8)
