    Just finished. Curved needle worked quite well, once I got the proper curvature. If I ever do another tank I am going to invent a clevis clamp for those strap bolts.

    It is only fair that the STC holder get a return on their investment. That is the primary reason for requiring authorization. But - and this is my opinion only - the STC is a lot like a perpetual...

    Nothing happens. Incorrect, unsigned, unauthorized 337s get filed every day. Only when an investigation starts do they ever get looked at by a person able to understand them. That way for over a...

    No way. As I was putting it in, I thought: never gonna do another PA-18 tank. Hands are not small enough.

    Think that's bad - thank God my Decathlon tanks are 1977, and not 2003. I have done two...

    The wing tank was an addition - unapproved until this year. It is a J4A, s/n 4-635. Dan has mentioned you. I would love to buy a set. Thanks!

    I have seen a lot of ground loops lately. Only one resulted in that kind of damage, and that is because the pilot went to full power and full back stick on the bounce. It almost went inverted.

    They will give the authentic restoration look. Of course fabric flaps and ailerons will help - and the metal stuff you have might bring good prices.

    Thanks guys. Is this like my Mustang convertibles - special tools to get that spring safely in and out? Or does it just relax when the strut is fully extended?

    Maybe, but seems to me a failure of the shock strut will result in a 45 minute repair - especially if you have a spare gear leg.

    We had badly corroded shock strut fail on landing. We replaced the...

    That looks just like the damage I am repairing. Pilot bounced, the aircraft lurched left. He went immediately to full power and full aft stick, and it snapped.

    I have an 11" Sheldon, but am trying to picture holding and cutting a spring. Aren't they hardened by the heat treatment?

    Wow! I would never have thought of that. Not sure I would have that kind of courage. If you do that, pre-tap the rib holes. An 18" Snap-On screwdriver is not enough.

    I am impressed! Very...

    Dakota Cub makes wings. They quoted three months, so we just bought spars and some ribs. Their parts are superb - not 100% sure they interchange with Piper. One phone call will probably say "yes,...

    The Stearman is getting a Garmin GDL82. It is bolted in, and they called me about the antenna ground plane.
