Subject: | Tractor type prop wanted |
Hi Gordon
That power plant is that not a Lycoming 0-235, if it is e-mail me off
line as I also have one installed we can swap notes. I am running a 74"
dia by 44" pitch, on my next prop I am going for is a 76" dia by 42"
prop. With my prop I get 2300 rpm static, with the GSC I ran I also got
2300RPM static and cruised at 85mph indicted at 2300rpm,
The prop did not seem to unload enough, you should try to get 2400
static.
Cheers

I'm looking around for a wood or metal tractor type prop for my winter
Piete project, using a Lycosaur 0-235. Anybody who hasn't converted
their dreams into a lovely clock, contact me off line.
Thanks-Gordon Bowen

Norman,
Thanks for email. I'm really attempting to use a Lycosaurus O-235, this engine
is an original pre WWII from Lycoming. 100 HP. I'm going to forward to you
an email I got from Jay Anderson in Texas that builds props. He also recommends
76" with 42-44 pitch.
Gordon

Subject: | Bending Allowances |
Got a question about bending allowances. Do the drawings of the
fittings that need to be bent already take into account bending
allowances or do I need to calculate them and adjust the dimensions of
the drawings accordingly.
Also, is there a spacer of some sort between the cabane fitting and the
spar where the fitting does not overlap the spar butt joint strap and
the pulley bracket? If so, what is it?
Thanks in advance.

Subject: | My Pietenpol Air Camper tires arrived today!!! |
Got home from a business trip today to find a couple of 21" Speedmaster Tires waiting
for me.....
My garage is SO full I won't be able to roll the fuse far but I WILL be able to
roll it before long....
I feel like such an idiot for getting excited over a couple of dumb old motorcycle
tires showing up at my doorstep but it almost brought tears to my eyes.....
This is SO much fun!
Life is good......

Hey Jim,

100) for anything had me counting the minutes until the UPS guy arrived....

Subject: | Re: Bending Allowance |
Jake:
Tony Bengelis covers this in his book "Sportplane Construction Techniques" by telling
us to make the bends first and then the ends are measured to see how much
to cut off. Also, he never drilled any holes until after the bends are made.
(page 40) Quote from Tony..."There you have it.....a fitting with the correct
height and base dimensions." Not a very professional way to make fittings, but
they will be accurate...consistently more accurate than many you'd make using
the metal working formulas involving bend allowance charts, setback tables
and that sort of thing."
Regarding the spacer: Look just to the left of the line giving the dimension "3-1/4"
between the two end attach holes of the pulley bracket and it calls out
3/32" ply both sides. If I interpret the plan correctly this 3/32" ply would
be shaped like a piece of pie...the bottom flush with the spar and the top would
be against the spar joint strap.
Finally...I hope this helps....and I can't say enough about how much Tony's books
have been so helpful to this amateur plane builder.

Subject: | Re: Bending Allowances |
In my opinion the drawings do not include bend allowances. Also, lots of people
have said to make the fitting's a tad bit longer (so they stick out more).
I guess it's hard to get the bolts in once the plane is finished.
