No Screws Spinner attachment

From the RV-List:

Hi Dan,
Couldn’t find much in the archives but I had an ‘old’ message from Mr.
Springer (on the list) which helped, plus I gave him a call. Actually, it’s pretty
easy to make the ‘NO VISIBLE SCREWS’ spinner – yes, you mount it from the back
with the top half of the cowl removed:

1-take the spinner and make the cutouts for the prop root.
2-rough up the area above where the REAR bulkhead fits inside the spinner.
3-tape the REAR bulkhead with some packing tape for a mold release trying to
avoid any wrinkles or use a mold release.
4-fit the REAR bulkhead to the spinner
5-lay up about 4 layers of the 8.9 oz cloth to make a ‘shelf’ above the
bulkhead. You’ll have a 90deg turn – some of the glass will attach to the inside of
the spinner and the rest will lay on the bulkhead which is your form. Do this
for both sides of the cutouts extending past the cutout for a full ‘shelf’ on
both sides.
6-When cured, remove the bulkhead and trim the ‘shelf’ leaving about a 1″
shelf all the way around (except for the cutouts…obviously).
7-Drill for platenuts – I used platenuts for AN3-5A bolts……6 on each side.
8-Make your little covers for behind the prop root and attach to the rear
bulkhead – I used .063 aluminum to match the spinner thickness.
9–Paint
10-Mount the spinner and go flying.

My old spinner had 24 screws. I’m real happy with the new spinner, nice and
smooth with no screws to wax around. Plus people ask….”hey, how’d ya’ do
that?”

Rick Gray in Ohio at the Buffalo Farm – thanks to Jerry Springer for helping
me with this and to Mike Stewart for convincing me that ‘I NEEDED ONE’! Yes,
it worth it!!
archive this one cause there is nothing in there to tell you how to do
it…..grin!!
