have 4:1 from 3000rpm dropping down to 750 rpm what gears to get 600rpm

Interesting but firstly Tony said to use this type of belt he should know. Secondly Pulley maybe wrong way round but its easier to change belt this way round without taking out whole motor or pulley off.

 

Havent sorted out pulleys as have been two busy writting reports to get in workshop

 

Cheers

It mght be easier to re-instate the 4 Pole 0.37kW Motor and ABB ACS150 Inverter Drive you have, with a 4:1 belt ratio. This would give full power delivery to the Lathe from 342RPM to 685RPM for 50Hz to 100Hz and good torque performance from 100RPM to 342RPM.
