If all else fails I have a board that was tweaked for power & rpm and tested (by a controller repair company on the left coast - I don't remember who) then never installed. It still has the test result paperwork with it. Cheap.
If you still need more torque, there are kits available that change the pully size on the motor and headstock, and use a different belt. These slow down the lathe a bit, which allows you to turn up the speed control a bit, and by using a different drive ratio, give more torque. The combination is noticeably more torque.
Did you get things worked out?
On mine there were 3 tunable pots that were blue on color with a small plastic slotted adjustment screw head. Each both on my board was labled as such if i remember correctly ....
Pot 1- "S" - which i assumed was the overall speed setting.
Pot 2- "T" - which was overall torque
And Pot 3- I dont actually remember what that was labled nor am i 100% positive that im right in my beliefs but i think it had something to do with adjusting the Automatic Fault circuit interrupter trip limit in some fashion but not sure at all.
Ive lately seen on here a few other variations to that circuit board when it comes to those adjustable POTs where there were 4 pots and where mounted on different locations but they always seem to be labled somehow.
