TP grinder take 2

[Stevohdee]

Hey guys,

Had a bit of a disaster with my original tool post grinder so decided to make a new one. The first model ran a motor from a ride on toy car but unfortunately lacked grunt not to mention torque. It did perform adequately until I needed to cut a square shaft on the mini with a 10mm milling cutter then gave up the ghost. The power supply overheated, motor stopped.
Here's model 2 and hopefully better.

cheers stevoh
