We see a lot of scratches from sliding ribs. But from your first pictues - early J3 spars were often laminated, both vertically and horizontally. ...

In California, "use tax" is a sales tax, and is the same percentage - one time. Each county then assesses a property tax. Totally different. ...

I agree on the 6:00x6, but prefer yellow Cubs. My personal J3 has a stripe as dimensioned above, but it is red with a black pinstripe. My bear is...

Pinking shears. Know how to sharpen them. Good straight scissors. Ice pick. Good paint brushes. Good containers - I really liked the old metal...

There is a way to escape - you probably need an expert or an attorney, and I personally would get a written guarantee. I believe it goes this way: ...

Where would I go? I grant you our idyllic paradise is very close to freeway gridlock - this town was 100,000 when I got here; over three million...

Yes. And if you go to Nevada, buy said curry comb, and immediately return to California, you are supposed to declare it and pay a "use tax".

Piper production in the late decades of last century - yellow with black bolt. 6:00x6.

Every time an item changes hands for money it is taxed by most states - new or used. Has been for years - decades. They are just getting around to...

Yep. Use that. A lot of ugly bolts out there. Opinion.

So are patented items. I did say “opinion”. Piper doesn’t have to release drawings either, but if it is on the TC we can do it for free.

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...

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...

I updated my statistics.my home airport, right now (well, 2017 data) is at 58% of its 1977 activity. A huge percentage of current activity is...

Nothing happens. Incorrect, unsigned, unauthorized 337s get filed every day. Only when an investigation starts do they ever get looked at by 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...

Good place to ask - what is the technique for those rib stitches below the gas tank? Right now I am using a curved needle and poking an extra hole...

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...

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....

Pavement only - 8:00 x 6 look good, but are pricey. 6:00x6 are stock for that vintage - look like crap, but work fine. Big tires may look gnarly,...

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...

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...

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...

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

Well, bump! i now own the J4 I spent 100 hours in. Much more fun in the left seat. Yeah, one gear leg is sagging. I wonder if stretching and...

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...

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...

I have done both AN fittings and a single #3 Aeroquip, and the original Piper style using auto brake line stuff. From what information I have, the...

Really? A triennial report was required in the 1970s? How come they never cancelled my registration - I never sent any reports to them. Some oufit...
