Guys,
-
I heard a rumour that Aero Composites (the propeller manufacturer) is no lo
nger trading.- Can anyone please deny or confirm this?- If true this is
very bad news.

| Subject: | Overtrimmed Cowl Top |
It looks like I've over-trimmed my cowl top... this is where it
currently falls with the 1/8" spacers between the face of the cowl and
the back plate of the spinner and the spinner centered visually on the
backplate. My choice at this point seems to be to either live with it,
increase the space from the back plate and push it back a bit or raise
the nose of the cowl up a bit which should also push it back (or some
combination of the three options). The space you see in the picture, at
its widest, is 1/16"
What say ye?

The paint's gonna fill a little more of that than you might think,
especially where it kind of wraps around the edge. I'd be pretty happy
with a fairly consistent 1/16 before paint.

Like Dave mentioned, I think you're fine. Paint will make that 1/8' gap
disappear.

I made my cowl to fuse gap 1/16 all around. Not painted yet, but assume
the paint will fill some of that.
I made trimming mistakes on my cowl and easily fixed them using the
methods outlines here:

Jeff you can rebuild that pretty easy with some epoxy and chopped glass.
Take some thin aluminum strip .03 about 1" wide. Wax the aluminum 2 times
Before putting on the cowl. Now slide it between the inside of the cowl and
the
Hinge. It should be a little tight just enough to hold in place.
Then mix the 1/32" chopped glass with the epoxy. Make it like peanut butter
or a little thicker. Then apply it. Let it cure overnight and sand it out.
I did this on one side of my cowl that I felt the gap was to large. No
problems
Hope this helps

Do I understand correctly, you are setting up for a 1/8" space between the cowl
and spinner? If so, recommend at least 1/4" spinner to cowl gap. This will
also solve your cowl to firewall gap issue.
Remember that you also have leeway in the spacers you use to mount the spinner
back plate to the prop. Assuming you are using a Hartzell prop, your minimum
(if memory serves me) is just using the 1/4" spacer. You can add up to two 1/16"
washers to this as well. I used the 1/4" spacer and one washer so that when
all was done and painted I could move the spinner back plate 1/16" closer or
further from the cowl. I ended up just leaving it as it was.

You can also supplement what Geoff suggested using fibreglass tape, it works well,

Sorry - I meant to say a spinner to cowl spacing of 3/16" to 1/8". I did 3/16"
and it ended up a little tighter after prep and paint.

Hey Jeff,
I have said before that in real life the gap between the spinner and the
cowl can be at least 1/4" (as others have said here). It keeps the spinner
from getting into the cowl when the engine "shakes" on shut down, and makes
it a bit easier to install the lower cowl without scraping its paint on the
spinner. I can't see that a tighter tolerance on that gap between spinner
and cowl helps anything anyway. I would have no second thoughts at all
sliding the cowl back and sanding the high spots to make a tighter fit if
your gap is 1/8 " or more at the firewall. If you are painting several
coats (i.e. base coat/clear coat), 1/16 may be about right. If you want
the "Swiss Watch" look and are doing 3 or less coats, maybe 1/32" gap. I
don't know any pilots personally that are dissatisfied with their -10 if
that gap is not perfect after flying more than 10 minutes ;-) 99/1
phase?
Later, - Lew

The wider the gap between the spinner and cowl, the more cooling air
escapes through that crack. It can come from above the cylinders or
below .... but that's a low pressure area and the air will find a way
out. But all is not lost. You can use the foam pipe insulation, the
size depending on the amount of space between the spinner backing plate
and the front 'ring' of the cowl to seal that area. Just split the foam
down the seam and glue it to the cowl 'ring'. The first time you start
the engine the foam will become a 'clearance fit'. ;-)

Leave 3/16"-1/4" gap. I built to 1/8" and it is too tight.
