KR> repairing skin damagge

[Martin Pearce]

I recently imported a KR2 from Canada and unfortunately it has sustained
some skin damage around the wing stub area in particular and has a big
bruise (crush) on the underside of the rudder where the tailwheel has
crushed the bottom of the structure. I plan to repair the skin damage by
using a hole saw or similar to cut out the fractured skin, glue in a plug of
foam and then use fibreglass with epoxy resin to repair the skin. I'm not
sure about the bottom of the rudder .

Any comments and advice would be gratefully received!

KR> VW cooling-sport plane builder

Glenn said a mouth full. I have had a flying airplane for over 5 years now and 
a couple times a year I pull out Tony's books just to page through and see what 
I want to try next. And there is always something that has become relevant.Joe

KR> VW cooling

[Glenn Martin]

In my Reading this morning I came across a hidden gem. It is in Tony 
Bingelis' book "The Sportplane builder" on page 94 (Cowlings chapter). 
On that page there is a picture of an airplane (possibly a Soneri) with 
the following caption:
 "The NASA duct just under the spinner feeds air under the VW 
crankcase for cooling purposes. ESSENTIAL TO VW ENGINES" (caps are mine).
I have been asking folks about this very same thing for quite some time. 
As an electronic technician, a thorough knowledge of component cooling 
is essential. When I first saw the cooling fins on the bottom of the VW 
engine, and realized that  in a VW Bug the cooling fins stuck out into 
the airflow, I concluded that in my plane I should have dedicated oil 
pan cooling which comes FROM the cool air inlet, through dedicated 
tubes, to a sealed  baffle around the oil pan fins, and out a dedicated 
tube from the bottom of the cowling. This dedicated air flow will keep 
the oil pan cool without reducing the low pressure required in the lower 
cowling for the cylinder and head cooling air flow. I'm not one for 
making something more complex than it needs to be, but in my field, this 
would be considered common sense.
 Agree or disagree with my point, we should all come away from this 
with one fact clear: If you DONT have Tony Bingelis' books in your 
library , you are missing one of the most important tools in your toolkit.
