20B Panel

Hi Guys
Does anyone have a 20B panel outline file that will work in Auto CAD
program. The 20B has a completely rounded top a flat bottom and steps
on both sides. It is different than a 19, 20A, and is the same as a
20C.
Thanks Norm

I'd be interested in the same kind of a file. Norm, do you have a 20B
with the tip up panel? Some of the first 20B "Hobbs" models were still
fixed panel. I'd be looking for the tip up 20B panel drawing.

Thanks,
-Kevin

I have a "spare" ASW-20b panel (The factory original, all full of
holes from my -20b) that I would be happy to send a full sized trace
of to someone so inclined to enter into Auto CAD. It is the style
that lifts with the canopy.

I would also be interested if anyone has a .dxf or .pdf

There is a crude hack I've used from time to time, take a photo from
about 10 feet away and import that into autocad as an image file, then
scale to the correct dimension. I would want to check it against the
original before sending out to the water jet or laser people but it
can be useful. Send me the photo and accurate measurements at critical
points and I'll scale it for you.

Hey Kevin,
I just realized you were one of the people in this thread, and that
you were talking about working on your panel. If I get a photo to
scale I'll plot it out full size and we could check it against your
ship. If a few people wanted them we could send the file off to my
cutter and he could water or laser them pretty cheap. What's the cool
material to cut them out of?

Brian,

I would recommend fiberglass or aluminum. Fiberglass is the easiest
to work with and if you have mistakes it is easy to recoupe. Stay
away from carbon fibre if you are drilling or sawing on your own. It
is hard on drills and saws and can easily splinter.

Do the finish after you have all the holes cut. I coat my panels with
Stone Finish (available at Home Depot) and then bake them in the
oven. Make sure the wife is gone. Preheat to 200F turnoff place
panel in the oven. Don't miss the turnoff! If you want a flat black
over the stone finish use wood stove high heat flat black spray paint
(Home Depot again) do the bake again.

While there may be some gliders that were designed with metal panels,
and some of them may use the panel as a structural member, I think
it's generally accepted that fiberglass panels are safer in a crash
than metal panels.

Of course if you never crash it's not an issue.

Make sure to use a reasonably long focal length or you'll have trouble
with spherical distortion.

Hi, Brian,

I'm working with Norm on his panel project. I'll contact you off-line,
and send you a photo of the panel, with measurements. I'll use my
Panasonic TZ3, which has a 28-280 mm lens (35 mm equivalent figures).
I really appreciate your help; I'm a neophyte with AutoCAD.

-John
