    I have always done it that way, too - but I wonder if it really makes any difference, now that we use stronger cements and dopes. In the olden days the perimeter tapes were notched, so only part of...

    Nice looking. I agree - I do not do nearly as much covering as you, but I learn something each time.

    This week I learned that Poly Tone can indeed be sprayed to achieve a gloss. I fixed some...

    Doubt it. Without looking, I am not sure which tank that is, but my Air energy 11 gal tank came without anything more than an information sheet - didn't even have much in the way of installation...

    I only get them for the non-operating aircraft. I have three registered and flying; they never ask about those. It says "voluntary" and you know what they say about volunteering.

    You probably still need paperwork. The alteration has more to do with the diagonal through the tank than replacing the forward spar - as near as I can tell, most of the Super Cub wing components are...

    Yes, Inhofe was invaluable for GA pilots. I may not agree with his politics, but I sent him a thank-you note. Sorry he won't be there to help us in the future - but surely some other ornery aviator...

    Atlee Dodge has a lot of strange STCs. Might check there. A better plan is to sell the J3 and buy a lightweight PA-18-95 or 105. Lots less expensive.

    Steve is right, of course, unless you use nitrate/butyrate. But if you hit something the tip bow will crack at the holes.

    I use Pliobond, and I wrap 102 fabric, attached with Super Seam, and heat...

    Me neither. First, the ash bow is shaped. Second, ash bends on impact; aluminum stays bent. Third, ash absorbs shock better when you hit that fencepost or the hangar door. Fourth, it is probably...

    Don't ask us. Your insurance underwriter is looking for ways to not "pay out." One reason is if you were not truthful on your application. If they say "PA-18 is the same as Carbon Cub" get it in...

    Seems to me if you are careful, gluing a ring on wouldn't even require touch-up paint.

    I have had some luck with it. Getting there is a guessing game, and when I finally get the text up I cannot remember the sequence of steps I took.

    I rather suspect Piper got their screws from Parker-Kalon. Spruce really didn't get started until rag wing production had stopped.

    I would order THA4-4 for leading edge to rib, and THB4X4 for...

    Maintenance is problematic. One weak cylinder on one single differential test and they all come off. Cub annuals routinely breaking ten grand. Bungees replaced at two year intervals. Covering a...

    I think they are all 4x1/4, but the ones that go in the spar are "B". Think of that B as "blunt end."

    Piper, way back when, had really shallow slotted head PK screws. If you can find them, your...

    Thanks. We are about halfway through the sanding process. I am not shooting urethanes, and was relying upon the skill of those who do. We are planning to have it smooth down to 400 grit, and then...

    First, thanks for the input. I am now convinced that we need either Aerothane or Randthane, and that two stage processes are out. Tomorrow I will have a knowledgable mechanic begin the wet sanding...

    By the way, I sprayed Delstar on my J3 in my driveway in 1981 (acrylic; six bucks a gallon). It was over butyrate. It still looks pretty good. No orange peel. Shines like a diamond. Fatigue...

    As I understand it, the Delfleet would have been just fine if they had thinned it with the proper reducer. And shame on me for not double- checking the color mix.

    So it is possible that Teresa's...

    The reason I did not spray Aerothane is that they changed all their colors since this aircraft was assembled. I have never been able to simply purchase a matching color from Stitts. Closest I could...

    Tandem Cubs have "wash" of two degrees from fuselage centerline to the outboard rib just outside the aileron cove.

    I don't spray urethanes - but know that they produce really nice finishes. The Ar Tech, Aerothane, and Ranthane finishes are usually drop-dead gorgeous.

    I agree - I have never worried much about the twist when covering or painting, and once the wing is on the aircraft it can be adjusted without any wrinkling. Good thing, since there seem to be a lot...
