Aluminium Pipe/Fittings

Unread postAuthor: rna_duelers » Tue Aug 28, 2007 5:26 am

Just wondering,can anyone clear up if 40mm BSP Aluminium fittings are available.For use in my Hybrid,for welding a nipple onto the chamber(made from Aluminium)and I would rather not have a 40mm hole tapped into the chamber,as that would cost a pretty penny.

You can have the threads cut on a lathe, cheap. BSP is a straight thread, no taper, the only thing that needs to be figured out is the thread pitch and depth of the thread, and if there is enough metal to cut into it while still remaining strong. A machine shop could do this for you at a fairly low price, it would be a rather simple process (I could do it, if I had a proper lathe available).

just to add something here, BSP threads can have either parallel or tapered threads.

just to keep information correct on the forum :wink:
