Don't throw away that old T25! Build your own JET engine!

[FattyBoomBatty]

I happen to have a large semi turbo for this very purpose. And an informative book on jet engines. I lack a welder and time. Also, Unless you have a gearbox made, you have to have a battery powered oil pump and fuel pump.

edit: upon further inspection, that dude's flame tube and combustion chamber designs look like they are from 150 years ago. Foyst, He's got horrible flow characteristics, and B, the flametube - lets just say flame holder rings are more betterer. He has a bunch of mumbo jumbo about oil coolers and filters. BAH, I say, BAH!

I could make a better turbo-jet engine in my sleep, it would have an afterburner and pulsejet unit as well. That guy = Rank Amature.
