Re: [TeslaTurbine] Digest Number 228
- I believe the problem can be overcome by gradually increasing the
amount/speed/volume of air directed at the discs. I had problems when I
directed too much air at once, but most of my problem was that the discs'
press-fit would slip out of alignment when the discs spun unequally.
Anyway, don't just blast the air on the discs; gradually increase the flow
until you're at top pressure/top speed.

I investigated the router bearings. They out priced me for the time. I'm
extremely low budget.
My main question is: Does the CD-TT require rivets and washers along the
outer rim? I believe they do because a preliminary test with an air hose
using only 80 psi made major disk warping. I intend to use 120 psi on the
You can get a cd tesla working dirty and cheap by friction mounting or
glueing it on a pipe peppered with small holes in the area with the disk
pack and using bits of plastic glued near the I.D. for spacers. But
remember 12,000 rpm max and that's only if you don't have any stress
from the friction mounting. Saves trying to machine balanced holes in
the cds that aren't very machineable. I think it was 99503 bearings
that fit the shaft. Pretty standard and 2-3$ ea but take off one shield
wash out any grease and put in light machine oil.(or you can rob them
out of old car alternators.) Ps don't use crazy glue to mount the disks
as it has almost no shear strength. You can make a good enough volute
from cereal boxes or even better crazy carpet plastic.
