I'm hoping they will become parts for a turbojet.
They take about two hours each and are somewhat
rough. I'm new at this so I really don't know how to
get a nice smooth finish. I assume you run additional
finish passes with finer increments then hand sand and
polish. If you have a 4 axis machine you can make them
by repeating the tool path for one blade and rotating.
As far as the turbojet, I've been wanting to build one
for years. I've built them before using automotive turbochargers
with impressive results. The problem has alway been with heat
and the bearings. But now there are space-age materials and
ceramics which can handle the temperature and high speeds
(so they say). So far it's been one technical glitch after another.
I'm sure when I have something to brag about I'll post it on this forum.
Thanks for asking.
