I should add to that! I have said many times before to make sure that you
have the spinner/spacer/prop that you are going to use before you start
building/installing your cowling. If you don't you are going to either be
space strapped with the prop/spinner hitting the cowling, or you're going to
have a prop and spinner assembly that has so much space between it and the
cowling that you are going to hate the look (might not flow air too well
either!)!

You won't be happy with the final "product" if you just follow the MAM
instructions for cowling installation and then try to fit a spinner/prop
assembly to it later. You need the prop/spacer/spinner assembly to get that
clean professional fit you're desiring, with an even gap all the way around.

Sold a 10" one to Bob Johnson and it came with the bolt holes predrilled
from UHS, but since there are so many blade profiles you are left to cut
your own blade holes out (weren't you Bob??)!

Using the UHS spinner would allow you to have the prop at least 3/4" (The
MAM spinner's backing plate is about 1 1/8" but can be trimmed down)

closer

to the cowling, as they (UHS) don't use a backing plate behind the prop.
With UHS spinners everything bolts onto the front of the prop and the
spinner wraps around enough to cover the blade width (or at least most of
it, depending on the spinner diameter used).

Just curious if the UHS spinner will work with the Sensenich 2 blade

metal

prop? If yes, does it come fitted with the prop holes, or do you have to

cut

them out yourself?

Bruce, Howard's original installation, on his speed cowling, was
a McCauley
prop with a 1 1/2" spacer. To use the MAM 13" spinner I had to
trim the back
plate down to 3/4" width (and the spinner to match) to give a 1/4"
clearance. I think it would be hard to get the cowl to fit properly on

the

engine with no spacer (but with some tweaking you might pull it off).

I

imagine you can get down to a one inch spacer, but it might take
some glass
work!
