Second attempt

Having some time while waiting exam results I thought that I should do something with a water pump which didnt had enough flow rate to actually pump water anymore. So I cut off the pump part of the pump.

 

So I got 330 W motor.

Next I drilled 12mm hole into aspen log and put it onto shaft. Fixed motor on the table with clamps and put a piece of angeled iron in vise to act like support for turning. And here is finished pulley 6cm in diametre.

I did the same with a pine log for the other pulley. About twice larger to get speed down. Now I had two pulleys. It was time to do some Sketchup modeling.

 It actually changed a bit to give more tolerance between the bed and a table.
