Tom Myers’ Mechanical Wonder
Tom writes: This model is actually a combination of two models from the 1930 #10 manual – the “mechanical wonders” section. A “bell crank drive” and an “out-of-line drive” are both driven by an A-49. I have not only substituted the newer motor for a P-58 but have also used newer base plates instead of a GA plate. As a kid in the fifties/sixties I was very attracted to the motion erector sets offered, I never, of course, realized what a 1930 #10 offered!
Tom Myers’ Multiple Straight Line Drive
Tom writes: This model is from #9 mechanical wonders “multiple straight line drive”. Mine uses some newer parts for base plate and an A-49 motor. The 1929 manual gives no indication how the AT axle is connected to the two EMs. I connected mine with a P-15 so it only really connects to one of the EMs. The two Hs must be aligned on the same spot on each CJ for symmetrical push/pull. The AY does not really do anything but looks good and maybe keeps the action smoother.
