Tail feather bearings

The elevator has one of these little straps on each bearing. I think they are there to act as a safety or to make up for a crack. The rudder uses the same bearing assembly, but this plane did not have the straps there. I used Titanium cuz I had some! It took 4 tries to get the process for forming

It's hard to see in the picture but there is a strap on that bearing.

Certainly, not original if on a 108 series Stinson.

 It's certainly not a 108, this is the Model 10 forum

Seemed like an OK mod to me.

@ecos36gmail-com  Michael, our 10A had similar looking elevator bearing retention, but I don't remember whether it was a strap or a casting in which the bearing was pressed.  The guy who restored our bird remarked that he could not locate replacement bearings for the elevator and reused the originals.  I remember when we owned the airplane that there was a lot of slop in those bearings.  The restorer said that he just packed them with grease.  What kind of shape are your bearings in?

These bearings are all tight, I can't feel any play at all You would need to cut the elevator or rudder apart to change one. It's hard to imagine a plane that had flown enough to wear these out!

I wonder if there was some sort of service letter back in the day that addressed the hinges? They might be something that was made in the field cuz mine are a better fit than the old  straps, but it's that took a while to get right.

@ecos36gmail-com  I'm pretty sure our old bird has over 3000 hrs. on the airframe now.  It was a CAP bird that did coastal patrol off the NC coast in early WWII.  The airplanes were based in Manteo and Beaufort, NC.

 This one has flown 1800hr, in the last 80 years. It has spent most of that time broken down, often sitting outside in the dry west. There had been a rats nest of fiberglass insulation in the wing root, fed water by a leaking wing tank tape job for some of those years.

 Makes me wonder about the future of this plane. At that rate it seems like if you kept it flying and in a hangar, it would last another 80 years.

Sorry, I missed noting that this was for a 10A or baby Stinson
