The CAD work is nearly done. Here's the cut sheet for the wood parts:
Ian has agreed to make the grip for the control column. This is a really important piece since it is a focal point and everyone is going to want to "take stick in hand" :-) Thanks Ian!!! Here is a CAD drawing I worked up to get him started:

I've made some progress on the main framework and begun the welding on the seat.
The main ABS framework is now complete. I've begun work on the smaller (1-1/4" diameter) framework that goes behind the instrument panel.
Here's the first part of the side framework. I'm using the 'scrap' steel tubing I got at a local supplier for cheap. They sell it for a few bucks per pound. I'm having to rub the rust off, but that's not a big deal and worth the savings.
Here's the same assembly after cleanup.
My welds are getting a little better... :-)
Here it is laid over the plans so you can see the context.
I'm thinking it may be worth the time to make a jig. Assembly is going to start getting complicated when the two sides are done and it's time to join them!
Just as in soldering, the pieces have to be aligned and held firm (clamped) while the welding is done.
So far I would say that welding like this isn't easy, but it's not rocket science either. Just takes some practice. I can see that to get really good at it would take time. I have a new respect for professional welders though. It's hard work, especially in warm weather! We're having indian summer here and it was in the low 90's while I was doing this.

Since this project is as much (maybe more) interest to family and friends, I've created a blog on blogspot.com. I can continue posting in both places, haven't decided yet. This isn't really an R/C project anyway, and the interest level here doesn't seem very high.

Given the posting format is quite a bit different on blogspot.com, I'm not going to post in both places. If you want to follow the project, see the link above.
Thanks for all the tips and encouragement guys. My welding is getting better. Should be ready for an apprenticeship when I'm done :-) I get the impression that oxy-acetylene welding is a dying art though. The arc welding equipment has been improved a lot. Still good for a hobbyist like me though. It's very versatile, with different tips you can weld small parts (read R/C model landing gear) very easily!

Just thought I would post a few pictures of the finished product. I'll post a few pics of how they used it after the documentary airs (probably in the spring).
I duplicated the hand lettering on the instrument panel best I could. It came out pretty close I think.
