Dereck, I don't understand where FS-1 is. I certainly will consider all suggestions. If a support brace is needed someplace I want to understand where.

I believe that is WS 1 on your photo - the part trapping the bolt head.
If that is what Dereck meant, I agree completely. I have some 1/8" triangles on mine and you could use either 3/16 or 1/4 hard balsa triangles.

Build more, websurf less

Dillion,

I believe your oak wing holding block is more than strong enough, however; It is tied only to the leading edge and the center rib.

I therefore recommend that you install additional bracing to share the load. How about two more ribs, one on each side, maybe at the width of the fuse. Then add gussets from the three center ribs to the oak block.

Looking good.

Oops, sorry. Should have been more attentive, reading it upside-down. It's WS1, the near semi-circular horizontal former under the wing LE.

Braces


I added the braces to WS-1 and glued in the rear wing mounting wood for the rear mounting screws (Nylon) I glued a small triangular piece of wood under the mounting wood for strength.

"W" Really? You really think two more ribs are needed in this wing? The original uses a hook lip and thats pretty much just glued to the W-1 Rib only. I have to think about adding that kind of weight to the plane.

Wing Bolts


I completed the wing bolt on section. Installing the thread insert, epoxying everything, both WS-1 and mounting wood for screw attachment.

Was pleased to see all the lumber so far only weighs 25 ounces.

Whats next??? The wing tips maybe, have I forgot anything on the fuselage?
Wheels are on order.

I found the top of the wing easier to cover when cap stripped at the polyhedral break. They are added to the ribs and not on top of them.

Doesn't look right


I attached the wing tips and am beginning to add the top spars. Does this look right. Is the spar suppose to look like this? I'm thinking I might "Crack" the spar right at the rib to give the wing tip a straighter look. What did I do wrong?

I cracked a spar and clapped it in place, this looks better.

You definitely have to crack all the spars at that last rib.

Cracked Spars


I cracked all the spars, added webbing, and Gussets.

Still have the other side to do.

It 'Bee' looking good! As long as you have all the gussets fitted, albeit to 'scale' sizes, it'll Bee fine

Sanding Lazy Bee WING


So this was more than I thought it would be. Took almost two hours to shape the Leading and Trailing Edges. I started out very practical, using a sanding block, then progressed over to my Large 100 grit sanding block. My thinking was that I need to be careful not to break anything. Well this is one tough wing, I can't be lieve how strong it is. In handling it tyo sand all of the edges, I only knocked out three Gussets. I feel thats good. A NOTE: When sanding this wing, handle it by gripping the web area, which is by far the strongest area. Below are some photos of a rounding sanding block I made to keep the leading edge consistent and the other sanding devices I used.

I used a razor blade then sanding blocks on mine. Last weekend I picked up a master airscrew razor plane to try out on my d-vii build. I'm doing a build thread in the fuel warbirds section if interested.

I was going to fly my Bee last Saturday but the 12-15 mph winds scared me off. I did a fine job of crashing my ult bipe 40 though! It was a arf so I had no emotional attachments.
