I'll guess... Mitch asked Necrosis about Necrosis' project, and Necrosis posted the information that Mitch was asking for.
Does that thing kinda look like a big cat to you?

Looking very good! :) Nice job on the threads too.

Why did you decide to place the spring externally?(Or is that not a spring retainer on the valve stem?)

Very nice, I have always liked custom hammer valves. I have a design floating around my file drawer with a design for a 'reversed' hammer valve that is part of the bolt, rather than the breech.
Completed projects:
CA1 SMSS Basic Inline
CA3 PDAB Airburst Cannon

Current Project: Bolt action rifle (25x140mm + 1in shot)

Nice. Will this be used to pilot a gun?
Could do semi-auto if you used a modded QEV.

It is a spring retainer, it will be adjustable using a threaded connection, so it also kind of acts as a regulator ish device.

This is just a test piece, stainless steel comming up today or tommorow. : )

Yes it'd be used to pilot a pilot gun for my railgun. *confuzzlewuzzle*

I thought you were going to make a gun like the condor but oh no that wouldn't have high enough volocities for you!
You can tell how awesome a cannon is by the pressure used.
