I've been doing lots of research and I have been reading a lot about Hubb's design but can't find the tutorial anywhere, I went to his forum and still can't find it. Can someone post a link please or point me in the right direction?

Type hbb library in wiki and theres a link to download plans there

That 2" piston valve is a really easy valve for someone just starting out with them, which is the primary reason I did that. I do recommend you upgrading when you can, however, since this piston (although it does function well) tends to be heavy. And make sure you have a decent bumper for it, as I busted mine on the first try.

My current piston is a modified version of the The Slayer Valve by origin unknown and I was able to net approximately a 50 fps increase and reduced felt recoil with it over the Hubb piston.

Hubb is right, that piston is extremely heavy. I use it, but I'd recommend using a spool design like the one Hubb linked to. It will be much lighter not to mention easier to build. Also, if you can, use nylong hardware.

Thanks for the help guys
