I flew this plane a few times years ago, very nice. I would put it up there with a Bellanca Cruisair or even a Pitts for the way it feels. The O-235 really makes it nice, the old engine would have been a struggle.
I want to get it flying again by early next year, (2021) and make OSH that summer.
This could have failed!
The bellcranks and hinges were pretty bad. I ruined one bearing before I figured things out. If a ball bearing is frozen, soak it in lube and then boil it with a heat gun. I grit blasted everything else. Getting all the hinges to line up along the rear spar wasn't that hard. I used a string running through all the bolt holes and shims to adjust the bearing hangers.
All the factory bolts in the wing are drilled, even the -3 and -4 AN bolts, with lock lock nuts.. I wonder when the rules changed, cuz now it's a -5 as a min size for a drilled bolt and a self locking but.
Looking good, Michael. Do you plan to replace the flap return springs? Or make sure you have access to them if one breaks in the future. I've always thought the O-235 might be a good match for the 10 series, if built light. I think the O-290-D2, which is what we had in our 10A, was a little on the heavy side.
I had not thought of that problem. I did look the springs over when they were painted but who knows about an 80 year old spring? I once took a tail wheel spring to a blacksmith shop and he beat on it with a big hammer and pronounced it good to go.
@ecos36gmail-com Yeah, they have been known to break. Also if they're too old and tired you won't be able to get close to the cable tension specified for the rigging.
I think you could inspect all the drag wires and change a flap spring but it would be a pain.
I'm glad I covered the controls first. I feel like I have one wing left in me.
These are the original 1940 wing spars. I have inspected them and they seem airworthy. If this Sitts job lasts, they will be pretty old next time anyone sees them. I wonder about that. 130 year old wing spars? It would be a monumental project to make new spars for a plane worth so little.
Everything is covered!
Two thumbs up!! Can't wait to see your bird finished. I love the baby Stinsons.
Thanks Dennis. I wonder about how much better it will fly than it used to. The old fabric and paint job must have weighed a ton. I also wonder about how fast your Model 10 with an O-290 was?
That was a long time ago (sold it in 1973), but best I remember it was about 115 mph.
The headliner took a long time to figure out. I've had the wool fabric for years and finally went for it.
One wing is painted! I'm using Stitts California Silver Poly Tone.
It might seem obsene but I rolled the finish. The fuselage is a spray job but I have had enough of that. The cowling and fairings will need to be sprayed but that is it.
There is a technique that you need to learn to not have bubbles in the finish but the result isn't worse than some spray jobs. In the boat world it's called rolling and tipping.
