Telespe Grinding Machine

Grinding Machine for Large Telescope Mirrors. I designed and built a grinding machine for mirrors up to 42 inches 1.1m in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work. The machine can also work smaller mirrors if the drip pan is moved to the fast shaft on the side of the machine.
