To clarify, I am simply making an engine. I am not intending to fly it, so
weight is of little concern for me.
Thanks again,
Dana

Subject: [AR] Re: Making propellant tanks out of aluminum gas cylinder?
This is probably way heavier of a tank than you need. But doable. People have
reused tanks like that. Even fire extinguishers at lower pressure.
As for the bottom fitting / hole - depends on tank construction details which
very, so possibly but no way to be sure.

Does anyone know if an old aluminum gas cylinder (AT size, 1.7 ft^3) can be
modified into a propellant tank for an inert-gas pressurization liquid fueled
rocket. The maximum regulator delivery pressure to the tanks is going to be
800 psi and the pressurizing gas is Helium. Fuel is kerosene, oxidizer is LOX.
?Can I simply drill a hole in the bottom of the tank and fit it with the
necessary connections as the propellant inlet/outlet? Should I use the body
(tube) and cut off the top and bottom and replace them with hemisphere caps?
Or is it a better idea to get a completely new tank fabricated.
It would work wonders for my budget if I could in any way "recycle" an old
gas cylinder, no matter how minimal. Any input would be greatly appreciated.
