The wing panels are ready to join. Tomorrow I'll make up the flap pushrod, cut the slot, then join the wing panels.
Today I built the weight box and installed it.
The bottom is made from 1/8 5-ply Birch, the side from 1/8 Lite-ply, and the linings are from 1/64 ply. The cover is made from 1/8 5-ply birch, 1/4 balsa, 4-40 washer (under the head of the screw) and some 7/32 aluminum tubing.
I had to notch the foam some to get the box deep enough into the wing tip. The weight box is secured with epoxy and micro-balloons.
The bell crank uses 1/8 music wire post, 2 4-40 fender washers, and 2 1/8 line eyelets. I use solder the secure the whole assembly. The ball link sits on a spacer and uses a 4-40 screw with a washer under the head. I used .027 lead out wire I got from Melvin Scheutte. Good people. I use annealed 1/16 brass tubing as bushings and LO eyelets. All wrapped with bare copper wire. Again obtained from Melvin. I then use clear heat shrink tubing to secure the ends.
The lead out guide is made from a center lamination of 1/8 basswood with the grain going vertical, and 2 pieces of 1/16 basswood with the grain lengthwise. 1/8 holes were drilled every 1/4 inch and the holes were connected with a 1/32+ slot. The end of the LO guide were the slot was started was filled in with 1/64 ply. The slot was fromed using my bandsaw then opened up with sandpaper.
The 3/32 balsa tips were added and doubled up with 1/32 basswood to provide some toughness along with a coat of thin CA along the edges.
