These models are from the 1929 #9 Mechanical Wonders set. The model on the right side of the back plate is the Cone Pulleys model, the first model in the wonders section of the manual and the easiest. The model on the left side of the back plate is part of the rectilinear motion model. All of the parts used are from the late 20’s with the exception of modern machine screws. The six shiny metal car trucks are from a mid-1920s Gilbert Meccano set. Special thanks to Joel Perlin for supplying the parts specific to the 1929 #9 set, those being the eccentric, cone pulleys and gear segment. These models do not really do much, they are more an exercise in getting your gears to mesh, which is not at all a trivial endeavor with sets of this era. I had to use a number of extra washers and brass collars to get smooth gear meshing. The motor is one I rewound, it is running at 3.0 volts and pulling 2.0 amperes in the video. On the front side is a back side is a basic reduction gearbox driven by a worm gear on the motor, the worm gear meshing is the hardest to get right. We then have ladder chain spinning two more gears. On the back side we have a crown gear turning three axels using the cone pulleys with women’s hair bands as the belts. The other side is an eccentric used to rock the gear segment across the saw blade. I really only included it so that one side of the back plate would not be so empty.

Larry Worley’s Steam Shovel

Larry writes: This is my Steam Shovel Model per the 1927 manual. It was fun to build and, after several adjustments, it now operates just fine. My dog “Tid-bit” often inspects whatever I’m building.

Larry Worley’s 12 1/2 Walking Giant

Larry writes: Just like every member; since I was a kid I’ve always wanted to build the 12 1/2 “Mysterious Walking Giant” model. Well, here is my example, built per the instructions in the “How To Make ‘Em” manual. The only alteration is that I used two stripped-out CJ’s for the ears.

Larry writes: Attached are a few pictures of my latest little gadget. This is the Drag Saw model which I built from a 1929 7.5 White Truck Set. It took about 2 hours to build and runs great. I have powered it here with an A.F. No. 2 transformer because my dry cells have gone dead. I used a scrap piece of closet rod which was already cut for my log. It is a bit large, but a quick modification at the front holder screws took care of that. I also substituted spoke wheels and removed the tie rod from an old MI steering unit. A building tip: Placing a BH solid collar on each side of the G strip behind the BT disc helps eliminate a lot of binding and blade drifting while running. Oh, one more thing, don’t install the P13 & CJ gears on the wrong axle as I first did. That blade was really moving!

Dave Ware’s Steam Shovel

This is a remake of the classic steam shovel. The boom was made moveable instead of fixed. A P49 motor was used with a modified engine # 10 to allow separate controls for the boom and arm; both at low speed. A string was tied to the bucket so that when fully extended, the string would pull on the release, opening the bucket.

Dave Ware’s Walking Giant

The Mysterious Walking Giant is taken from the 12 1/2 set of 1949. The mechanism that gives the giant a walking motion is also connected to flexible shafts that give the arms a swinging motion.

I was surprised to find out that the original Coaling Station from the 10 1/2 Electric Train Set only had a belt that went up and down and did not transfer coal to the other side of the model where the coal chute was. It also had no buckets that could hold the coal.

This Coaling Station doesn’t look much different from the original. However, a number of changes were made. The chute side was open up to allow the buckets to enter that area and a platform was taken out so that coal could enter the chute. The chute was modified so that it can be raised or lowered with a crank.

All this is under the roof which has been removed so things can be seen. The belt is two loops of string that go over pairs of Z flanged wheels with W stacks between them. Strips of cardboard glued at intervals on the string, keep the string properly spaced apart. A cardboard bucket is glued to one of the strips. At the bottom, “coal” (a ball bearing) is loaded into the bucket. As the belt moves, the bucket rises to the top as before.

Instead of going back down, it crosses over to the other side, where the “coal” is dumped onto the chute. The bucket returns to the other side and down to the start. At one point the W stack is missing to let the bucket pass through the Z’s.

Built with a 12 1/2 Set, the O pawls for the rippers and the MF for the fenders are slightly modified. S57 1 3/8 screws are used under the frame to jack the model up so it can operate stationary. 2 Z flanged wheels are used for the upper track wheels. It looks like Maurice has had a lot of fun with his bulldozer. Notice the wear marks on the P13B gear.

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.
