That would be me. I received my propeller from Jay a couple months ago in the rough.
Jay included a note asking that I call him prior to doing anything on the
propeller, so I did. That was when the conversation came up about leaving the
machining scallops on it. We had a very nice, detailed conversation and from
that, I decided to leave the prop. as received...VERY LITTLE sanding, not worth
mentioning really, almost enough just to clean it up from being handled. (skin
oils) I stained, painted and varnished the prop. and left all of the machining
marks on it. The "fields"...the area Jay calls the glass coated tips...were
not sanded much either, just painted and varnished. I personally am not a
big fan of smooth glossy finishes on some items, and leaving the propeller as
is and staining, left a very nice, "aged" look with rich texture and color...just
what I wanted.
Theory is that the scallops act like a bird's feathers, dimples on a golf ball,
or VGs, providing a better boundary layer on the airfoil. Jay told me that
others leaving the scallops noted better performance.
I figure that later, if needed, I can always remove the scallops... not so easy
to add them after sanding them off.
My propeller is now finished, balanced and on the plane. (not permanent as of yet,
working on tracking it now.) Very happy with how it looks, verdict still out
on how it performs, but I have no doubt it will be just fine.
Feel free to contact me if you want to chat further.
Merry Christmas.
If God is your co-pilot...switch seats.

I'm awaiting the completion of my Cloudcars prop as well and would love to see
a pic or two of yours finished Michael.

Im sure this has been covered but cant seem to find. What is common round tube
used in substitute of streamlined tube for the walking beam? Wall thickness and
outer diam please. Paul

Scott, It was my aerodynamacist buddy who explained how the scallops create
a turbulence right next to the skin that is slicker than letting the
air go across a smooth surface. This holds the boundary layer closer to the
airfoil of the prop and thus provides better "lift" which translates into
thrust in this case.
it is somewhat counter intuitive but there it is.
Blue Skies,

| Subject: | A65 eyebrow cowlings |
Aircraft Spruce saves the day again.
Remember, I am restoring/reassembling a plane I did not disassemble. So I
spend a lot of time figuring out where things go.
For the life of me I could not figure out how the eyebrow cowlings went on,
They interfered with the fancy old style sparkplugs and leads John K. had
put on the engine. Nothing fit. I searched the internet and could not see
enough detail to see what I needed. Then I saw a set a eyebrows that
Aircraft spruce has for sale ($464) and lo and behold, there was a set of
brackets that explained it all. I then dug in the box of extra stuff John
gave me and found the eyebrow cowling brackets for this plane. That
additional spacing fixed everything.
However, I am reasonably certain that I should not undo the nuts holding
the jugs on to mount this bracket. However there are not enough threads
left for the bracket and a full sized nut. What do y'all do? Put a
thinner nut on?

Steve,
I put my brackets on the cylinder studs and then put the nuts back on. Be
sure to torque them per the engine overhaul manual. Also, be certain your
brackets are steel, not aluminum. My first brackets were aluminum and I
found that in about 50 hours the nuts got loose. Good way to blow a jug! I
mentioned that to an old-time Cub guy and said, yeah you've got to use
steel. Aluminum will always "work" enough to let the nut get loose.
Good luck!

| Subject: | walking beam streamlined tube alternative |
Paul,
I made mine like Pietenpol control horns, .032 or 22 ga edge welded. Made
somewhat like Ken Perkins design, it is suppose to help out with the
elevator cable slackness.
It is 8 1/2" long, 1 1/4" wide in the main body. The aft holes are 7 1/4"
apart(the same as the elevator horn), the front holes are 7 3/4" apart.
My plane has not flown yet, hopfully in the next year or two.

I believe Continental used Pal nuts to secure them. Only takes a couple of threads.
AS&S sells them under MS27151.
