A bigger valve

Here is a larger version of an actuated valve assembly.   The first version is based around a 1/4" Swagelok valve (SS-4P4T).  This version mates a 3/8" SwageLok 1/4 turn plug valve (SS-6P6T or B-6P6T) to a Hitec Standard size servo.



There are two printed parts:

Testing the New Chambers




Just a quick note that testing is proceeding with the new Printed (3D printing, DMLS, additive manufatured) chambers.   The cobalt alloy turns an interesting green color when it gets warm.

Blue Flame

Its been quite a while since my last post.   Things have been busy and I'm working several nifty projects.    I wanted to share a picture of a new igniter that I've made for a new project.   It's designed to run on GOX/Kerosene and works well so far.

Printed Widgets

I'm finding that 3D Printed parts are pretty handing for custom brackets and widgets.   I'm currently working on a new chamber project and needed a mounting bracket for it.    The part took me about 30 minutes to design and costs ~$15.
