Your A&P is correct. It isn't the reduction in area of the crankshaft that's the problem, but the rust pitting creates stress risers where the crankshaft has a greater likelihood of cracking and...

Thanks. I'll go search that out on SuperCub.org. I'm on that forum as well. Thank you.
Our EAA Chapter is restoring a pre-war J-5 and have decided they would like to paint the registration numbers on the wings as they would have originally appeared using the NC registration number on...
I don't believe Epoxy resin will bond to a Polyester resin very well. Many polyester resins have a "waxy" finish to the surface. If you want to laminate glass using an epoxy resin (such as West...
Quite frankly, people make too much of a big deal out of break-in procedures. I prepare for the first flight the same as I would with if the plane had an engine that was already broken in. If you...
As a tech counselor, your thanks is enough. I'm there to share what's in my head and really seek nothing in return other than to see you safely enjoying your creation when it's done. If you want to...
I've done upside down wet layups with fiberglass and carbon fiber. It's not easy or fun as gravity is always there and this stuff wants to fall off. If you have little composite experience, it's...
Let's see where the mistake lies. Shown in the photo below, there is a #1 stamped into the cover right next to the #1 plug lead. Make sure that goes to #1 cylinder. If this is a left hand...
One more thought which might explain why things would be off by 90°. If you are aligning the timing marks on a flanged O-200 crankshaft with the part line on the case, it should be aligned with...
OK. Your symptoms and your description are telling me you have the magnetos 180° off. You installed your magnetos with #1 cyl at TDC at the end of the exhaust stroke rather than at TDC on the...
Let's take a methodical approach to this. You have to have compression, fuel, spark, and the spark has to be at about the right time. One of these 4 items isn't right. So let's do a quick walk...
I would suggest you volunteer to organize programs for the chapter. People volunteer for chapter leadership, then all the sheep in the chapter do their best to keep them so they don't have to...
Did you assemble the engine with liberal amounts of engine assembly lube? Or did you just assemble with a little oil? With lots of assembly lube on the critical components internally, I'd say you...
It looks like a pretty standard pipe thread dope, so should be acceptable on pipe threads.
There was never an automatic failure at <60 psi compression differential. Many mechanics would call it a failure, and often times cylinders were failing at that pressure, but not necessarily so. I...
Exactly right. The number isn't so important as whether the cylinder is leaking and what is leaking on it. Exh Valve, Intake Valve, rings, cracked head, scored cylinder? Large bore Continentals...
.040" for your standard Aircraft engine compression differential tester. A .060" special orifice can be used for big bore engines although most don't bother. Most mechanics will compare...
Personally, I would use the cleaning solution (KBS Klean) from KBS coatings. I have used it on Aluminum and composite tanks to clean and prep for repairs with very good results.
I would guess there is no air flow through that heat shroud over that section of pipe when the heat is shut off. If that's the case, the pipe will overheat and can deform. Ensure there is always...
When I was a chapter president, I was criticized for having too much technical and builder content in our meetings and not enough to satisfy members there aren't interested in building. :eek: You...
You need to adjust your attitude about what you are hearing just a bit. The reason these folks all talk about RVs is that their only point of reference is the RV line, i.e., they don't know any...
Oil pressure regulator on the right side of the case above the dipstick tube. Take is apart, clean reassemble. If you have the adjustable one, adjust appropriately. If you don't you may need to...
They are listed on Ebay ranging from $200 - $400 as they are being replaced by the gross by 1090-ES capable transponders.
This is something that would be accomplished under Experimental Exhibition. FSDO can help you with the legalities of that. Not a difficult change to make.
However, I am not aware of any...
Unfortunately, static prop strikes can cause cracks at the flange itself. I wouldn't sweat having the rods and gears magnifluxed, but the crank should be. I bought a C-85 from a friend after it had...
