Hello everyone. I will try to explain my problem the best I can. I am fairly new to operating a metal lathe. I picked up this Lodge & Shipley lathe a little while back and have just started using the machine. I have 2 pics one of the machine and the other of the geardrive area. So here is the deal I need slow the speed of the lathe down right now where you see the belt that is set for the slowest speed, I also have set the transmission gear to the lowest setting as well. I need to tap some threads into a bung. So as you can tell in the pic the two gears to the left are my back gears. Basically when i run the machine those 2 gears are not engaged. But when I engage one of the gears and try to turn it on It basically struggles to get going then the pully will just spin inside the belt. I just don't understand what is happening, the belt has pretty significant tension on it seems like enough to make the machine want to stall then it finally just starts spinning and belt stays there. Any ideas?
