Need backgear Help

[everyjuangohome]

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?

HI Everyjuango home,
When operating with the back gear engaged you need to find a pin that connects the cone pullys to the chuck and disengage it. OTW the back gear is trying to reduce the spindle speed and the cone pully is still trying to operate straight through, ie: 1:1. BIG JAM UP

This is what Noel is talking about. There should be a pin to pull to release the belt cluster from the spindle bull gear, and you know about lifting the back handle...Bob
