OK, pretty much finished the stabilizer and elevators. All that's left to do is some detail sanding just before I cover them in Monokote.
After elevators had cured overnight I sanded the LE flat, installed the elevator horn, positioned them over my plans and marked and trimmed each end. I then capped the outboard edges with 1/32 basswood using medium CA and the inboard edge with 1/16 basswood to provide a little extra stiffness. BTW, these elevators are stiff!
Once the elevators were done, I now can taper the thickness of the stab/elevators toward the tip. The stabilizer/elevators are 17/32 thick and taper to about 3/16 at the tip. I accomplished the taper by attaching the elevators to the stab and placing them between 2 pieces of 1/2 angle aluminum with 1/32 shim underneath to bring them up to the 17/32. The aluminum pieces were tapered to give me the proper taper.
The stab/elevator were placed between the "jig" and a sanding bar was made from some 2 x 2 and 80 grit sandpaper. Some 1/4 "guides" were glued on to "center" the sanding bar over the jig.
I then use this set up to sand in the taper on both sides of the top of the stab/elevators. I then flipped over the assembly and shimmed up the tip to the proper height. I then sanded in the bottom taper on both sides.
I then sanded in the "sharp" LE and rounded the TE. Then went over the entire stab to sand smooth and blend it all together. I use some 1/32 basswood to line the stab edge where the elevator is to provide some strength but most importantly to give me a crisp edge to Monokote to. The TE were kept about 1/8 thick.
The stabilizer weighs 37g and both elevators weigh 39g. The 3/32 elevator horn weighs 8g. The stabilizer is 27g under budget. The elevators are 1g under budget. For a total of 28g under budget so far!
