I am the new neighbor, as of 9/11/07. SHe is always on the beach, I never see her hubby around. SHe lives around the corner, and visits my next door neighbor a lot for play dates for their kids. I have been told he is pretty laid back. SHe is a teensy bit flirty, and always diverts her eyes long enough so I can get get a good long look at the beach.
Silicon with acid - you can smell the acid if it is in it. good point, that is why i am posting, to find out stuff like this that I don't think about or don't know about. This stuff is mild to the nostrils, and intended for use with aluminum gutters. I will remove the excess. I just need a little bit to hold the sleeves in place. I have found silicon used originally for this inside the tubes, with no corrosive effects, and the craft was built in 1986.
I wish I was getting more responses on some of the other questions I have had here. Like rivets.
THe stub spar was originally overlapped into the wing spar just 1", which is the thin, skin sheet aluminum bent into a channel shape and attached to the stainless stub. 90% of the attachement and stress was taken by the skin attached to the stub by rivets spaced 1/2" top and bottom. Now the coupling is a 1/8" x 1/2" x 8" 6061t6 bolted in four places by AN4 (one of the inboard bolts is not yet inserted in the stub in the photos), and also steel riveted between the bolts (also not yet done in the photo). The skin attachments to stub and the vertical stab take most of the stresses. (You can see the close spacing of the rivets into the stub in the final shot, completed) THis is a neutral wing with 0 lift, so I don't believe vertical stressing will be significant factor in cracking and failure. THe buffeting from the prop wash is more critical, right?
I considered a 1" wide bar instead of 1/2", but it would not fit between two rows of rivets holding two layers of the stub together, and I felt a flush mount was more important than beefier stock.
This feed back is very useful, I wish I was getting more. HELP! I am an idiot and need your tips.
I would like to know how homebuilders shape leading edges of aluminum airfoils? I had particular difficulty with this one, and I am not 100% happy with my results. I have no brake to use. It seems impossible to do without one.
I gave up on polishing. I don't have the luxury of the time to spend on that nonsense, even though I love the results when it turns out right. I painted the mast black, it was almost 80 here yesterday and no wind, so a perfect day for painting outdoors. It will match the rest of the frame tubing.
