Mounting Fisher Price Gearboxes

[Dick Linn]

Years ago, when the drill motors/transmissions still came with the actual plastic drill casing, we used expanding polyurethane construction adhesive as a bedding compound to form a flat base on the curved case. We put waxed paper on a flat surface, rigidly held the case in the proper orientation, then squirted the glue in the gap at the base, followed by a couple of wedges of scrap wood. Once cured, we held the whole assembly down with large hose clamps. We used PL Premium, which is available at Lowes I think. They have many types, but this particular one will stick to a lot of different materials, including metal. It costs about $3.50 a tube.

If you use this stuff, do not get any on your hands or clothing!

We made a custom aluminum plate that bolts up to the FP gearbox. Then we put a 90 degree bend onto the bottom part and mount it to the robot, to mount them vertically. I'll post pics later tonight.

The 36mm gearboxes aren't a good choice for the FP motors. They fit the 42mm gearboxes, however, Nanebots has sold out of all their high torque 256:1 gearboxes, and will not be getting them back in stock. This leaves only the 64:1 as the gearbox with the most torque, which might not be enough. The stock gearboxes are 124:1, which might be a better option for your team now anyway.
