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.

New additively manufactured regen chambers

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.

DMLS Chamber Version 2

Here are the specs for the redesigned version of the DMLS chamber.   This project pending interest and resources.   Drop me a line if you would be interested in supporting a project like this.

More Valves

I've been doing quite a bit of parts with Shapeways lately both flow models and functional parts.   One of the latest is a rework of my servo actuated plug valve.

Two parts allow a Swage-Lok SS-4P4T valve to be actuated by a Hitec servo - I recommend a high torque metal gear model like the HS-7954SH.   The only other hardware required are (you'll need taps to clean up the threads in the nylon):

qty 4     8-32 x 5/16" Socket Head Cap Screws, McMaster-Carr 92196A191
qty 2     4-40 x 1.25" Socket Head Cap Screws, McMaster-Carr 92196A302

The printed parts are available on Shapeways
