| Subject: | Re: Rotec Engine |
Rodrigo, here is my personal opinion. I love radial engines, but I am not a
big fan of the- Rotecs. I do not know much about them, but I do know tha
t they have an internal gear reduction unit. This unit seems to give them a
bit of a whine which I do not care for.- Again, in my opinion, they look
a bit large for the Pietenpol as well, both in the number of cylinders and
the actual diameter of the engine.
-
I am looking for a more vintage radial for my Piet., so if anyone ever hear
s of such a thing for sale, please let me know!
-
If Rotec is listening...if they make a 5 cylinder, 90 HP, non whining radia
l cheap enough for most home builders to afford...they would make a killing
!

Curious, is it necessary to sand off any epoxy smudges prior to varnish? I
wonder if the varnish covers them up nicely or do the smudges show through?

Well, you will pay a small weight penilty if you use solid 1" spruce on the
ends as opposed to the normal "routed" type. One way to get that same shap
e is to epoxy two pieces together. (Picture attached)- The other picture
is of the tapered sides for the elevators. I modified my elevators some, so
the taper is more pronounced.
-
Looking ahead to covering... if you use the solid 1" spruce, that wide 1" f
lat will be visable under the fabric. You'll see that 1" border on those si
des, where as if routed it is 1/4".

The epoxy will seal the wood just as well, if not better, than varnish.
So, unless the part you're varnishing is visible I don't see the need
to sand the epoxy off prior to sealing it with varnish.
Now, if the part you're varnishing is visible, i.e., in the cockpit, the
varnish may not adhere to the epoxy nicely and it may not look as nice.
I'd probably sand or scrape (with a sharp paint scraper) the epoxy off
prior to varnishing.

Well guys, I still don't have the annual done on 92gb, I have been working on a
hanger addition, to get my tractors out of the main hanger area. It is a mudy
mess! I hope to have both the Piet, and the hanger done before the Ohio Piet
"Party", on june 19. Putting up a pole barn without help is making me wish
I was still in my 20's, it hurts more now than it used to. At least I haven't
missed any good flying weather since last week, I think I will go out and play
in the mud now, happy flying.

How are you going to "attach" the trim cables to the elevator bell
crank? This is how Mike has his arranged:

That little extra bell crank welded on the right side (in the picture)
of the bar is attached to the trim knob under the seat, here:

I figured I'd attach the cables to the pin shackles already in place
on the bell crank ends to which the main control cables are already
attached to. The trim cables will go off to the left, so they
shouldn't foul the control cables. I'm open to suggestions, though.

| Subject: | tightness of fit? |
So I started today on the horizontal stab as the first piece that I am building.
I have about enough room to slide a piece of paper in the tightness of my fit
between my diagonal braces. Is that too much or will the t-88 expand and make
up for it?
Thanks,
Bill

That will be just fine. You do not want a starved T-88 joint any way. The g
ussets, that come later, are where the strength comes from.

Probably just getting picky here, but T-88 will not expand to fill the gap.
It will bridge small gaps, but it does not expand.
If the gaps are too large, and you're using straight T-88 (no fillers) you will
come back later to find that some of the glue has run out of the joint. But in
your case, with a gap the thickness of a piece of paper, you shouldn't have
any problem.
That polyurethane Gorilla Glue stuff does expand. But I wouldn't use that glue
on my airplane. It isn't really strong enough for aircraft structural applications.
