Well, when scratch building something of your own design (well mostly your own design) you have to be ready to cut something apart. The cabanes gave me one heck of a fit and taught me something in the process, while it is somehow possible to solder 4130 Chromoly, I certainly don't know how to do it!
So that left brazing the mount tabs on to the cabanes, which is to hot to do while they are in the fuselage so cutting them out I did.
While I had the out I decided to re-make the cabane brace "V". Now it is an X. Made the cabanes a little bit stronger and also gave them the proper angle going into the fues.
The cabanes re-worked and remounted, also changed up the mounting a little bit by sandwiching the cabane U between sheets of lite-ply.
Made new F2 and F3 bulkheads, and put the stingers back on.
Nose sheeting finished, not only are the cabanes stronger you can now see that the apex of the cabane brace going into the fuse is wider and looks more like Grampa's.
I think it's about time to get started on the wings
Chatting with dad while I keep comparing mine to Grampa's lol
Had to move one of the stingers in F4, left a good sized gap but there will be a mahogany instrument panel that covers it up

I'm not sure yet, I'm going to do some experimenting before I start covering. I've used Koverall and Dope before but I've always needed to use a lot of filler. Grampa could put Koverall down so smooth he'd never need to use any, so I gotta learn how to do that myself

here's a link to the museum in Ashland KS where the airplane is, has a few color pics www.pioneer-krier.com/vewebsite5/exhibit1/e10005a.htm...

WINGS!!!!
With the fuse mostly framed up, tonight I got started on the wings. I decided to build the bottom wing first so that once I have it a little ways along I can build the landing gear, then it wont have to sit on the belly anymore
Got started by using my 1" Forsner bit to put holes in the ribs for the aileron servo leads.
Next I laminated the 1/8" lite-ply W1's together, these are the ribs that support the landing gear rails so they need to be strong as possible.
Making up the spars. The spars are 1/4" sq. bass wood, and I staggerd the splices in the sweep to help even out flight loads.
All the ribs are in place, in this picture the top spars are just sitting in place. Tomorrow I will get started on the wingtip bows.

Either a DLE 35RA or an EME 35. If I end up needing more nose weight I may get the auto start kit from Mile High.
