Thanks Chuck, I am lucky to have a matched hole wing kit and tail kit. I dont see how a wing can be built crooked with a matched hole kit. I do remember that the weight of my Horizontal Stablizer was alot and I built it flat on a solid wood door mounted to a steel frame work bench and it lined up pe...

Thanks Chuck, I have clecoed and drilled 4x8 ft section of skin on a 737 that became delaminated and corrosion was setting in between the layers. That large section of skin never moved and the clecos held it well in place. The thought process you mentioned sounds like the way to go as long as it doe...

Welcom Ron, I have found most my questions answered in a matter of hours, with great accuracy and knowlege of other builders that have been there and done that before. Another benifit of this sight is builders share there mistakes and photograph everything that helps there fellow builder. This is by...

Thanks Chad, Its been a while since I used it in the Airlines as a structural mechanic. I didnt know if it was the same material. Thanks for reasuring me about the mill spec number. I know the tubes it comes in is alot easier to work with a pneumatic seal gun that I have. It will do alot cleaner job...

Is 1422 B1/2 or 1422 B2 compatible to use as a tank sealant.
We use it in the airlines for the fuel tanks on jet planes but that is kerosine based.


Thanks.

Thanks,
I will try to contact Mike Sewart or talk to some of the rocket guys about any mods for strengthening may be required.

Does the fire wall have to be reinforced to accept putting in a larger engine.

Any comments on doing this would be appriciated.

Thanks,

Mike Balzer

Thanks Will & Dave, I will take what you suggested into great consideration when assembing my wing skeleton. If I remember correctly I think I clecoed the ribs on the Horizontal stabilizer front and rear spar and drilled the skin, then I disassembled everything deburred all holes and dimpled the rib...

Why are most people riveting the ribs to the front & rear spar before they drill the skins. Is there a problem with clecoing the ribs on the front & rear spar, then drill the skin and dimple the ribs with the pneumatic squeezer in a vise. I am almost done deburing the ribs and would like to make the...

Congratulations on your endoresment Brian.

I dont have a real pilots license yet, Only a Hang Gliders license. I plan on getting all my instruction on a T/W aircraft from the get go.

Congrats,

The 7 Rule -3 rivet use a # 40 drill 3+4=7 -4 rivet use a # 30 drill 4+3=7 -5 rivet use a # 21 drill 5+2=7 (use a 21 for better tolerances) -6 rivet use a # 10 drill 6+1=7 Just drill the head enough to break the manufactured head off the rivet by taking the drill and wiggeling it in the hole or a 3/...

Nice Work,
Looks like you have access to a lathe and other machine shop tools.

Keep up the good work,

I did not mark my bolt gage correctly. My stupid mistake.

I may have marked my bolt gage incorrectly. I called vans and they told me the bolt should be 3 1/4 long. I will measure the bolts this weekend and check my bolt gage also. I am to busy during the week to check the information above. Thanks for the reply Mike Balzer I inventoried the bag as a kit wi...

Thanks for putting in the time to convert my hang glider picture to the right size and making it work for the Avator.

I am building a RV-8 and just finished the tie down brackets. The aileron bell crank bolt in the print DWG -15a shows that an AN 4-32a bolt goes in the aileron bell crank through the bronze bushing. This bolt is supposed to be supplied in bag 1993-1. When I looked in the hardware bag the bolts were ...
