Having never made anything move before (except the motor lab a few weeks ago,) making our record player spin was a real challenge. Louise and I spent more time than we had hoped talking about the mechanics of the device. Our goal was clear- we wanted the user to be able to spin the tray manually OR with the motor. We were afraid that there would be too much friction between the motor and the tray, preventing it from spinning without the motor turning. With great luck, once we went ahead and built the platform, it did exactly what we wanted! If only we knew…
Some thoughts on the way it might work:
Alas, IT SPINS!
Thanks to Tak, Merche and Eric for the advice!
