I recently picked up a second hand Central Machinery T5981 machine. I've been cleaning it up and exploring what everything does, but one lever is completely puzzling me.
It's in the picture attached highlighted by the red square. The other two levers control the auto-feed on the 2 axes, but this one I can't figure out what it does. By coincidence the lever also broke off of that one during transport in my truck, but I can still turn it by hand or by sticking the old lever in there. Waiting till the weekend to drill out the hole and just tap it for a bolt that I'll use for a new lever.
Thanks for any assistance offered!

I am not familiar with that machine, but it appears that the lever is for the half nuts, which are used for threading. If so, there's usually an interlock that prevents the power feed lever from being engaged at the same time. I suggest you engage the power feed, then try to engage the broken lever. If it won't engage, that's most likely what it does.
Alternately, at slow spindle speed and with the carriage away from the headstock, try engaging the broken lever while the spindle is turning. If the carriage is propelled, that's what the broken lever is, the half nut lever.
When using the half nuts, be careful to not allow the carriage to hit anything. That generally results in something being broken.
