Default showplanes cowl

The showplaces cowl actually has an inner fairing to smooth the flow around the nose gear...

Gil, Greg is speaking of something like the standard exit radius on an -8. You've seen the idea adapted to other models.

The -8 has an exit ramp inset into the belly, so the inset has sidewalls. The stock ramp is aluminum. A stainless overlay for a 10 could be curled at the cowl end, very much like the ramp in the foreground (here upside down on the bench), a one piece SS panel with integral sidewalls for an -8.

Thanks, but I was wondering about the work fitting around the -10 nose gear, which is different from the -6A I'm familiar with. I'm also guessing that the lower cowling "bar" referred to was for the alternate screw (not hinge) mounting, but it wasn't quite specific.

I'd bet it was for the bracket that ties the cowl to the bottom of the fuselage. None of the other models (except maybe the -14) have that.

There's a lot to work around down there on the -10.

But, isn't that the U-620 and U-621 stuff on my -6A? Plans sheet 61.

I removed the heater cuff off of the right side. I have never missed it.
The scat from the left side connects to the SS diverter during winter and dumps overboard in the summer. That alone solves most of the problem. When it is in use it goes into a Y in the tunnel to provide heat fore and aft and it is plenty. In the summer I also use exhaust tip extenders since I have an A/C duct.
The fresh air that used to supply the right side cuff now goes direct to the SS firewall diverter and from there straight into the tunnel to ventilate it with cool fresh air. . In winter I have to close the valve in cruise because it gets cold to the touch. With this controllable setup, my tunnel and fuel plumbing stay “room temperature” year round.

Maybe I'm ignorant of how the -A models work. Wouldn't be the first time. ;-)
