My two cents on the trolleys: Admittedly, there is a lot of weight on the tailwheel of an H-36. I thought long and hard about a mechanism for lifting it, such as overcentering devices. I found that I can just use a lifting strap (a loop of mountaineering webbing in my case) looped under the tail boom. From an upright position, I can use the strap to just lift the tailwheel onto a wooden platform with four small casters. I am not a powerful man, but surprisingly found this much easier than I had anticipated.
For the mains, I fabricated dollies with plate sheet steel (1/4 inch thick) with angle iron sides welded on to provide wings for mounting four casters, leaving the floor of the platform about 1/4 inch above the surface. A piece of angle iron is used as a stop on one end of the platform (inverted and welded on as a pyramid or triangular piece). The opposing end of the platform overhangs as a lip providing about 6-8 inches of overhang for rolling the main tires on. As the tire is rolled on the platform, the overhang overcenters and creates a ramp. As the tire advances onto the platform, the weight shift again levels the trolley and all four casters are back on the surface. I have a 5/16 inch rod that goes through holes drilled in the angle iron sides that acts as a stop to prevent the tire from rolling off again. I was surprised at how easily the tire(s) will roll up the slight incline, especially when tire pressure is up to spec. With these devices, I can easily pull my H-36 into the hangar by a wingtip, although it sometimes takes a couple nudges on the fuselage to get all the casters aligned in the desired direction. This is, of course, a solution for hard surfaces. I'm sorry I can't provide photographs as I am at my winter home some 800 miles from the hangar. But the point I do wish to make is that the main wheels will easily roll up a slight incline, and just using as lifting strap to lift the tail is much easier than expected. With that, it may be possible to avoid a whole bunch of complexity. An imperfect solution, I find, but a decent solution for me.
