Agree - and "B" type, so they don't have sharp points.

Rolled threads are way stronger - and I am not advocating cut threads. But in shear, is thread strength or stress raisers a real factor? I use...

I agree - these things are hardened. Move the new hole several diameters laterally - do not try to drill close to the broken screw. I found that...

If it is in shear, why would you need to roll the threads?

I have found that doilies over seaplane grommets are essential - especially in the propwash.

Thanks for the tip. I almost sprung for some.

SuperCub stall speed with the cruise speed of a Piper Arrow, unbelievable Yep. Not that an Arrow is all that fast.

I don’t think I could agree more with Waldo - except to say that my J3 with Stroker, starter wing tank, and PA-11 struts, seems as agile as it did in...

I have a Narco 810R that is acting up. I am going to slam a GTR-200 in there and never look back. I could probably get it repaired for $2-300, but...

Just trying to counter the desire of purists. Len used to tell folks how horrible the dash 12 was, and because of that, two Cubs now belonging to...

I can see I will have to go back to saying “opinion” on each post. I really don’t have all that much experience with heavy aircraft, and admit to...

When you get older you will regret not having the dash 12. I can still solo prop at 82, from behind, but the day is coming when all starts are...

That’s true. If your mission is carrying a load out of remote, very short strips, the more power the better. If your mission is to simulate such...

No. It would be the same as a C-90 or O-200 with reground crank. But somebody in Alabama has been approved to bring crankshafts back to standard,...

Got that right. They go straight up, but lose all their charm. Heavier is often not better unless your mission is straight up. As I recall, the...

I am not much for competitive stuff, but I practice power off approaches in everything but turbines. A billion years ago I lost a contest for spot...

Really good point. Did not know the D&E wings were that heavy. Dakota wings are slightly heavier than stock -and for me, the lighter Cubs are the...

Sometimes it is the broker. I am finding that AIG has no problem giving me a free “waiver of subrogation” to do a flight review in someone else’s...

One of the most useful options for the aircraft owner is the specific acknowledgement by the FAA legal memorandum that an owner may provide the part...

I know nothing of the difference between billet and forging, but other than that if you supply all the necessary data, you do not need a PMA. It...

I think you can legally do that. Owner-produced parts. Let us know if you can get it done for a grand or so - Probably Continental does that -...

Don’s Dream Machines?

To answer the original question, check out the definition of major alteration. If not major, you need only a logbook entry. Form 337 is never used...

8:00x6 are plenty good. I used to spend portions of each summer in and out of grass strips south of Atlanta with no problems at all on 8:00x4s. A...

Of course it will. The problem is that it will probably kill your passenger, for whom you may have some feelings of affection. For Super Cubs,...

I am with Web. I hate to taxi into a runup area with Cherokee strobes on. Wait 'till those students are in the right seat on a major airline - the...

We crossed posts. As far as I can tell, we are not in disagreement about anything except you thinking I aimed my comment at your installation. I...

Yes. My post was triggered by Glenn’s photo, not yours. And I stand by my comments. As an aside, my shoulder harnesses were illegal from about...

Well, me neither - except for the rear belt, which will collapse a diagonal tube that is not under load. I thought we were having a theoretical...

No, you missed the point. That particular tube is under compressive load in normal flight, unlike the tubes your passengers grab. The feds are...
