ETC chamber design and machining questions
Posted: Wed Apr 15, 2009 8:59 pm
Hello all,
I am in the process of designing a ETC (Electrothermal-Chemical gun) chamber. Here is what I have so far:
1.875" 1045 high carbon steel
11" long
designed for .5" OD barrel
Here is a CAD:
All the small holes are what hold it together. Threaded rod goes through, and I tighten it up. The barrel also acts like the interior sacrificial layer to take all the burn. The aluminum slides in, and screws through the bottom right piece tighten to hold it there. Does anyone have any suggestions for improvment?
A machining question.
How can I make sure that I can Drill straight down, without the hole slanting? I do not have accsess to a metal lathe to turn it down.
Any comments or suggestions or critisism welcome. Please refrain from brining up the actual fuel. I will not answer any questions regarding that. I have talked to DYI and some other people concerning this, and will be similar to his, if anyone kept track of that.
