High pressure compressor made from my old Jeep 1991 Cherokee's AC compressor. Now i have low cost high pressure compressor.
Made connectors for tubes in my lathe. Just need to buy long +15 meter tube, connectors and gauge for 20 bar /300 psi about.
Electrical switch for compressor so i can keep it next to my gauge.
Try to take some pics when its finished.
Now just need make strong bottle and test it with water.
AC's freon gases was gone long time ago, so this was easy solution for me.
No need for expensive pumps, or scuba tanks.
Cheers

Indeed, here in Finland all fun is not allowed. It would be fun to build real rocket engine with peroxide.
Just working with lathe the rocket nozzle, to help mist jet expand to right direction, for more thrust.

but somehow I don't see too much fun in C-stoff and T-stoff they were very very volatile separate or together. Melting my hand away because I splashed some on me is no fun
looking great! And you work really quickly too!!
thanks

Nozzle almost ready. Full bore is 20mm, with shims smaller can be used. I know with water straight tube is better, but hoping with expanding gases in thrust tube giving with this nozzle some extra thrust. And giving more scale looks and reducing drag. Small lip on nozzle is for launch mechanism.

Back on Me-163.
No its not toilet seat for pilot.
Its very tight baffle for engine. Small naca hole take air straight to cylinder and fins. 3 times bigger exhaust for hot air.
Just laminated it when cured cleaning and installing support wall and fire wall.

Plane out of mold.
Not totally happy, there is some bubbles, but nothing what filler cant fix.
And bit heavier than hoped. But fuse and wings are very strong.
