Do you have a PJ to experiment with, which model? No. I may build one this winter if I decide to go ahead with this project. I need to keep costs down. That's often the problem with great ideas and plans. If you're working alone you should be a PJ-expert, owning a number of different working PJ's, ...

I was first going to recommend flanges as reinforcements. But flanges will locally reduce the possibility for thermal expansion: flanges.gif This "choking" of the radial thermal expansion and the fact that stainless tends to get brittle and cracky (on a molecular level) after heating, might cause ev...

Jack,

You might wanna shield off your gas tubes from the heat of the PJ, or your hair is gonna be on fire, and more..
And perhaps you have to turn the gas bottle upside down for better fueling.

Jim,

The more details the better, also about failures etc.
Share them here please.

Mmm,
I would take a few weatherbaloons and first "float" my rocket and launchplatform into the stratosphere. From there it shouldn't be "to hard" te get in orbit.
