Just a note on unsupported engines, just completing a over haul on a O-300 which is unsupported. We have close to $25,000.00 in it. That's without any labor, just parts and machining. All I can say is be very careful on pricing a plane with a unsupported engine,

Well I managed to get in -- and out (turns out the builder strengthened the cockpit edges so I could pull-push up without damaging the sidewall stringersformers)... Unhappily, my legs are about six inches too long. My knees and shins want to occupy the same space-time coordinates as the bottom instrument panel. From what I could see, moving rudder pedals ahead 4 to 6 inches would be complicated. Thanks for the entry tips -- worked well.

Yes would be much easier to redesign the instrument panel.

Thanks for the cautionary note. I think I'd use this engine initially, but be on the lookout for an O-320 CS upgrade as a winter project. TBD.

That's a good way to go. If you can find a O-360 that's the ticket. By rebuilding it a little at a time it hurts less. The funny part is the 360 is about the same cost to rebuild as the 320. Just try to find a common model like the A1b. In Feb. I overhauled a 0-360A-1-P out of a Husky. The cam and crank are a little different from standard and cost a few thousand more than common. Good luck, it will be fun anyway.

I was using a milk crate to get up and down when working on my Starduster Too, but climbed up and down when flying. I ripped the crotch out of more than one good pair of jeans getting off the wing, and decided it was time to add a step. I'm glad I did. It was worth the effort, and will continue to be so as I get older and less limber. I made it a little over 4 inches long, and welded it to a .050 inch 4130 angle that was fitted to the cluster on the lower longeron. If I had it to do over again, I would make it an inch or two longer.

Looks good Dan! We need to get together. Mine has been down with a little issue and I hope to get it back in air next week!

Any pics of what you did to beef up the area? I'd be affraid it would twist the longeron?

He said he fitted it to a cluster.


I do use a step stool while working on the airplane but so far I have no problem getting onto the wing walk even with a chute. I grab the edge of the rear combing with right hand, left foot on wing and a little "jump" to grab the center section handle with my left hand. Now with the two place sliding canopy it's easier(no rear windshield in the way) to swing my left foot onto rear seat although the combing is now higher because of rails. Works ok now so far at age 70 and 20# over weight. That said, might need a step next month.

My issue is NOT getting onto wing but swinging my leg over combing onto seat.

Jack, I saw that he welded to cluster area. I just don't think, maybe I'm wrong, welding a 6"-10" lever you're going to be applying 200+ lbs to a cluster is enough to not cause a issue down the road? I like the step idea is why I ask. But I know how much force is applied by a awkward single footed exit on such steps...or at least I know I'd fret about it without some extra support or reassurance this is a non issue. It reminds me of the Eagle gear longeron issue. Every landing it rolls the longeron...with every entrance and exit it would do the same but with only the force of the human entering or exiting. Not the whole weight of the plane. Maybe I'm way over thinking it? I dunno I just thought I'd clear it up so if I decide to add one I'd know what is the correct method.

The step arm was welded to a .050 in. 4130 angle. This angle was bent with a 3/8 in. radius to match the longeron. The angle extended up and across the cluster a couple of inches each direction of each tube, like a finger doubler. Longeron tube and cluster is not under excessive load.

Seems a good way to attach the step to cluster. I suspect any fabrication good enough to not break off is good. I'm not an engineer but I think the load on the longeron from the step is insignificant compared to the load from the spring landing gear ?

Even a 300 #'er might put what 2 g's on the step? Compared to a 1800# airplane with repeated 3-4 G landings...or worse I wonder if we actually consider the loads absorbed by the gear?

Or maybe I'm missing something?

Jack
