I bought an Enco 110-0820 knowing that the power feed was iffy.
This is my first lathe and I have no real experience with lathes.
When I got the lathe home the power drive worked, sorta. In going through the lathe and trying to figure out its initial condition I noticed the gear box was loosely attached to the head casting and was wobbling pretty well when engaged. I took the front off and tightened the gear box. This completely locked up the drive system.
So, I took the apron off and disassembled the power drive worm system. The worm gear was pretty much completely trashed.
I counted the teeth and started looking for a replacement 42 tooth worm gear. No joy at all. Eventually I dug into the manual to see if it said which modulus (I am assuming this is a metric lathe, all the fasteners seem to be) and I discovered that the manual said I am supposed to have a 41 tooth worm gear.
Even I know that 42 is > 41 and that a 42 tooth gear is bigger than a 41 tooth gear. I guess this explains the lock up when the gear box is tightened.
I kept at it looking for a 41 tooth gear now.
Eventually I discovered that the Grizzly G4000 looks identical to my Enco. So, off to the manual for the G4000 hoping to be able to buy a replacement worm gear since Grizzly still exists.
What to my surprise do I find? The grizzly has a 42 tooth worm gear.
I can't (don't know how to) get a good reading of the center spacing between the gear and worm.
I am trying to get the power drive to work and I don't know if I need to find a 41 tooth gear or if it is easier to source both the worm and gear for the grizzly and if I do source both pieces for the grizzly if they'll work in the Enco. By looking at the parts it seems that a slightly thinner wall on the worm would make plenty of room for a 42t gear on the same centers. (of course if the Grizzly parts are just as difficult to find as Enco, I guess it doesn't matter.)
I have no idea how to cut my own gear and don't have access to a mill or dividing head.
Any direction will be greatly appreciated.
(as you can see in one picture I really doubted my ability to count teeth when I looked up the part in the manual.)
