Bruce Hansen’s Three Wheel Glider

This Three Wheel Glider was built from a New Wheel Toy set from 1919-1922. It was meant for a young boy to ride.

Bruce Hansen’s Coaster Wheel Toy

This Coaster was built from a New Wheel Toy set from 1919-1922. Bruce says: Guess you’d start at the top of the hill, put your feet on the axle for steering, wait for a push to get started and hold on for dear life!

Bruce Hansen’s Go Cart Wheel Toy

Bruce writes: The go cart wheel toy model is called a Go Cart. More like a Pull Cart in my mind; little tyke would have to convince big brother to haul the former around.

Bruce Hansen’s Helicopter

Bruce Hansen writes: This is a Helicopter model built from a 1962 No. 10181 Action Helicopter set. I used a rubber band for a drive belt instead of string. Other than that, it was built straight from the instructions.

Bruce Hansen’s Caterpillar Tractor

Bruce Hansen writes: This Caterpillar Tractor was built from a 1950 12 1/2 set. The P55 motor and treads drive the model along at a pace of about 3 inches/second.

These models are all built from a 1919 #9003 Outdoor Wheel Toy. Gilbert introduced the Wheel Toy in 1919 in two styles of sets: New Wheel Toy with wooden parts and Outdoor Wheel Toys with all steel parts. Here’s a picture of the smallest Outdoor Wheel Toy set, number 9003.

The OWT manual showed four toys built with the No. 9003 set. The featured model was the 2-wheel glider. It also built a hand truck, dump cart and a wheel barrow. Note that the last two models used the set box as part of the toy.

Bruce Hansen writes: This model is an SPLR (Self Propelled Lunar Researcher) built from a 1969/70 Master Engineer type III set. The set came out right after Apollo 11 had landed on the moon. Not coincidentally, a large number of the models illustrated in the manual were moon/space vehicles. The action in this model is a Powermatic motor/hoist powered crane with hook and boom control. Also, a pair of antennas rotates and the whole model moves forward/back via walking “legs”.

The Master Engineer set included two Powermatic motors and a 4.5V transformer. Both motors were not under power at the same time. A SPDT switch alternated power to the appropriate motor. Here’s a shot of the model’s back side showing the selector switch, hoist, motor for the crane functions and the antenna. The antennas were driven via a pair of P48 mitre gears and P7 pulleys/string. Type II enthusiasts will be familiar with the mitre gears which were included in type II sets size #6 1/2 on up for around 30 years. This happened to be the last set to include the mitre gears.

The drive “legs” are powered by a second Powermatic motor which is geared down to 1/4 its slowest speed with a pair of 14/28 tooth sprocket/ladder chain reductions. The output shaft has a BT pierced disc on either side with a “leg” made from a square angle girder assembly.

The model actually works quite well. The crane hoist is a typical type III setup which always worked well. The walking action was very smooth after I extended the “box” that the leg travels up/down and pivots on by 1/4”. In fact, it walked about twice as fast as the type II walking giant/robots I’ve built in the past (about 5 ft. per minute). The manual shows the antennas reversed from my model. I found the string/pulleys couldn’t drive the larger antenna so I flipped them so the heavy one was directly driven by the motor.

Bruce Hansen’s Light Tank

Bruce Hansen writes: This is the Light Tank built from a 1950 12 1/2 set manual. The P55 motor moves the tank forward/reverse.

There is an error in the manual regarding this model. It notes that the motor gearbox setup is “B” instead of “C”. The model moves along at about 3 inches/second with motor setup “C”. The P55 does not have enough torque to make it go with setup “B”. Plus the model would have theoretically moved along at about 27 inches/second!

Bruce Hansen’s Heavy Tank

Bruce Hansen writes: This is the Heavy Tank built from a 1950 12 1/2 set manual. The P55 motor moves the tank forward/reverse. The Heavy Tank moves along at about 3 inches/second.

Bruce Hansen writes: This Half-track was built from a 1949/50 12 1/2 set. The P55 motor drives the half-track forward and backward.

Underside view: the chassis frame is made from a pair of DP 12” angle girders. The P55 motor drives the model along at about 3 inches/second.

This model has a pair of idler pulleys which give the track a taller profile. This helps the model climb forward or reverse over taller obstacles (no problem with golf ball sized rocks).

Bruce Hansen writes: This model is a type III Cement Mixer truck model built from a 1963 No. 10129 Master Power set.

The 1963 Master Power was the only set to include a number of parts. This particular model used a couple of them, the #903 Programmer and the #931 Programmer reversing switch.

The #69 Powermatic motor sat between the #903 Programmer and the #95 2-drum hoist and powered both. The hoist shift lever was connected to the programmer with a link bar. In operation, the programmer cycled the hoist between its two drums. When the programmer reached the end of a cycle, a cam tripped the #931 reversing switch which reversed the motor and repeated the cycle.

In operation, the cement truck drove forward while the mixer bucket turned. After a 5-second “drive”, it paused and the dump chute in back lowered. The reverse switch was tripped at this point so the cycle was reversed, the dump chute raised, then the cement truck drove in reverse for 5 seconds.

A couple of trivia comments about this model: The Master Power set had 5 illustrated models, three of them used the #903 programmer. The cement truck model was the only one that used the #931 reversing switch. This model was also the last truck model that had steering. It had a working steering wheel and steering knuckles.

Bruce Hansen writes: This is the Lunar Drilling Rig built from a 1962 set of the same name (8 1/2 set). The motor in this model drives a rotating drill in the base and a rotating “antenna” (everything above the Boiler). The drill/antenna rotate at about 60 RPM’s.

Gilbert’s 1962 sets all had featured models on the box tops. This was the featured model of this year’s 8 1/2 set.

The antenna is made from base plates, angle girders, C girders, turret plates, a Boiler top and a few other girders/axles/gears.
