--> Kolb-List message posted by: "Rusty" <13brv3c@bellsouth.net>
IIRC from the last 912 school I attended, not recommended to run 912,
especially 912ULS, without the prop, which is an integral part of the
flywheel "effect" system. If the engine is properly pickled for
storage, there is no need to run it periodically.

---------------------
Thanks John. I was guessing that it wasn't a good idea. I can't see how it
would hurt the engine, but I'm afraid it would damage the gearbox. On the
other hand, we do this all the time with the Mazda engines and planetary
redrives.
I guess what I need then is a 2 blade prop. Has anyone ever seen a 912ULS
with a 2 blade prop? I need to call IVO and Warp, and see what they have to
say.
Thanks,
Rusty

Beauford,
I have used methlenechloride (sp?) in the past. It is a very strong
solvent and will weld the two together. I used it to make fish tanks. I
was a Murray State University biology/chemistry student at the time. Not
sure where else to get it.

Most any plastic company that sells Lexan or polycarbonate sheets
also sells the glue or "solvent". It's clear and has the consistence of
acetone. The bottle comes with a syringe like tube on the end.

Hey Butcher,
I would think " Super Glue" would work...
I use "Super Jet" ( medium viscosity )....any Hobby store...
I usually buy medium...If I want it THINNER , I use acetone to cut it.

Been test flying my Xtra for about 5 hours now. Things are progressing well but
I still have some fine tuning to do.
Originally had a 3 blade Ivo on the 912 but was getting a noticeable vibration
from 4000rpm all the way up to 5000rpm. Smooth above and below that range.
Switched to a 3 blade 70" taper tip Warp Drive and it is smoother but there is
still a vibration around 4500rpm. Vibration is not apparent during full power
run on the ground.
Anyone else had this problem?
Thanks,
Tom Sabean

| Subject: | Lexan Glue Wrap-Up |
--> Kolb-List message posted by: "Beauford" <beauford@tampabay.rr.com>
Possum, Giovanni, Brother Pike and all...
Thank for the responses about lexan glue... In the Kolb List spirit, I
provide the following information which was gained via your e-mails, some
daring in-house experimentation and utterly exhausting internet research:
1. Forget about Shoe Goo on lexan... after it sets up, it readily rolls
into soft, booger-like little pills and wipes right off with no visible
effect on the plastic...satisfying, in a primordial sort of way, but of no
real help in fixing the windshield...
2. Acetone, MEK and lacquer thinner really screw up the surface, but have
zero bonding/welding effect
3. As Giovanni said, and Google research verifies, the weapon of choice is
clearly Methylene Chloride, but unfortunately it apparently has roughly the
same effect on people as VX nerve agent... it is dispensed only through
specialized outlets, evidently by individuals dressed in rubber suits
wearing overpressure masks...and absolutely positively most assuredly cannot
be obtained casually on weekends from Home Depot by saggy-bellied goobers in
GI tee shirts and jeans.... Reading the EPA warnings, you'd want to carry it
in a hermetically sealed box, preferably on the exterior of your
vehicle...and consider carrying a live canary in a cage on the front seat
next to you...
4. A very hot clothes iron works well to smooth and de-burr the edges of
freshly cut lexan... supposedly, the iron does not leave the microscopic
cracks that emery cloth or Dremel wheels apparently tend to do (obtained
similar info from several hobby pages, there might be some truth in it)
Tomorrow when the plastics supply house over in Brandon opens, I'll go get
some ME glue in a tube, as John suggested. Meantime, i'm goin' back out in
the garage and roll some more of that Shoe Goo...
Worth what ye paid fer it...

Mike...
Just went out and tried two different cyanacrilate (sp) superglues I had on
hand on lexan scraps... could not get either one to hold... could be my
glues are too old...(everything else is...) But thanks for the input...

| Tom Sabean
Tom S/All:
I have used Warp Drive Props exclusively since Sep 1993. For the most
part, Warp Drive Props do not have balance problems. However, if all
two or three blades are not set at the same pitch, annoying vibrations
will result. Insure all three blades are the same pitch before going
any further.
Next, some 912 and 912ULS engines and gearboxes will get a harmonic
vibration at certain rpm as a result of loose shims in the gear box
torsional vibration dampner. Insure the dampner is shimmed as tight
as permissible.
If you have a 912ULS engine of the older variety, prior to "slip
clutch" and "high torque starter", would be a good idea to upgrade to
these items. Most, if not all, vibrations in my system disappeared
after upgrading to the slip clutch.
What kind of prop extension are you running? A poorly built extension
could add to you vibration problems.
Let us know what you find out.

fit a third tank in somewhere.

Beauford,
I know Im late in the game, but I was in Home Depot the other day
and they had some kind of glue for plastics. It said ,all, plastics. It was 2
part. The first part you put on the pieces to soften em up, then you apply the
other part on them & then assemble. It might work. What about the all purpose
glue for plastic pipe?
Let us know the outcome,

Rusty --
In a word, yes...
...but, I've also been spoiled because, on a different aircraft, I had an
Arplast 3-blade prop, and those have GOT to be the best props in the
world... It had the most powerful thrust I ever felt, and it was so quiet
I could cruise without ear protection. But they are pricey little cusses.
To be honest, though, I don't know if Arplast makes one that would be
suitable for a 912ULS... I had mine mated to a Rotax 503.
