| Subject: | Re: Model A carb heat |
John,
The reason for an adjustable heat box, is that warm air is less dense,
and gives less power. To leave heat on all the time , you wouldn't get
everything out of your engine.
Icing has very little to do with flying in summer or winter. In winter
, cold air can't hold that much humidity, to turn to ice.
In summer, you have those white sky days due to lots of water vapor in
the air.
The most dangerous days are when the dew point is very near to the air
temp.
Dew point is what temp. you need to drop the outside air to, in order to
make it rain. Where the air can't hold any more water. Warm air hold
lots of water,,,cold air holds relatively little water.
Take note of the Dew point on a flying day

Subject: Pietenpol-List: Model A carb heat
Most of the Piets I've seen run all the carburetor intake air through
a heat muff mounted on the exhaust stack. It's like carb heat is always
on.
Is there any reason to set up an adjustable control so that some or
all of the air to the carb is unheated?
Thanks,
John Smoyer

Gary,
If you want to include pdf's of the 'How I Make Wood Propellers' by Al
Schubert on the DVD (ROM) you can find it at
http://mykitplane.com/Planes/filesList2.cfm?AlbumID=5
Obviously anyone on the list can get it anytime from MyKitplanes, but
it might be nice to have the resource on the DVD also. I got this
'book' from Dale Johnson, who, if I remember correctly, had contact
with the family of Al and got permission to do with the material as he
pleased. I scanned the material a bunch of years ago so more builders
could get their hands on it.
There is also an old doc called Simplified Propeller Design for Low
Powered Aircraft that you could put on the DVD if you like - I'm
pretty sure that it is a government doc and in the public domain

Hi Gary,
I am still working on finishing my Prop Carving CD, the instructional essay
with diagrams and photos. I am getting closer to completion. One of the guys
on this list is kind enough to be helping me with some feedback so I can be
fairly certain this is all accurate and understandable to the masses when I
am done. Just a few more weeks maybe. Thanks for asking.

Hi Gary,
I am still working on finishing my Prop Carving CD, the instructional essay
with diagrams and photos. I am getting closer to completion. One of the guys
on this list is kind enough to be helping me with some feedback so I can be
fairly certain this is all accurate and understandable to the masses when I
am done. Just a few more weeks maybe. Thanks for asking.

Here's a site anyone working on a wing dihedral will find to be really
really helpful:
http://www.carbidedepot.com/formulas-trigright.asp
A bit over 1/2 deg (0.5509 degrees) at the root will lift the tip (at
approx 13 feet) to 1 1/2 inches...
Amazing what such a small angle will do over a bit of a distance...
