Success And Setbacks On The Cm 12x37

Well like the title says, some success and a little setback I hope doesn't turn into a major pain, if you saw my other thread on the HF 12x36 lathe you saw I got a pretty sweet deal on what was actually a 12x37 gap bed lathe with a bunch of extras, I knew it had an electrical issue and could only run it in reverse manually to check it out before I purchased it, well I brought it home around new years day and its been in my shed floor unroll this week, I knew it had a fried forward contactor so I found one on Amazon for less than twenty bucks but it took about three weeks to come from Hong Kong, I was busy so no biggie and I had to get it up onto the stand so I could work on it, a piece of 3x3 tubing slid through the rafters and some 2x12 lumber to form an a frame and a couple of chain hoist made easy work of it, so I got the new contactor in the mail and got it installed and success, got the green light on the panel, forward,reverse, all good, run her thorough all the gears, sounds good, runs nice and smooth, so now I'm in it about 517 bucks with the new contactor, so it's running and up and on the stand so I can get at it to start cleaning some of the muck out of it, it's filthy, I take the cross slide off and its got cosmoline and chips in every nook and cranny so I know I gotta go from one end to the other and get it clean, so I get down to the apron and get it loose and flip it on the the bench and the brass worm gear that rides on the lead screw is missing about three teeth, bummer, now what? Where you gonna find something like that ? Maybe cross it over to a grizzly machine but how to find out which one?

Do you know the MP of the gear? How many teeth? Looks like 18. Then just start comparing what you have to others. This may not help, but Lantaine made a 12x37 that may have been similar to yours.

I have no idea if this is helpful or not:

Hopefully this is not stupid, but might try contacting HF and Griz? There has got to be some way to chase it down.

Another option:

Called HF this morn, very nice guy and very helpful, but the worm is not available, no surprise really, talked to there tech also, he said he couldn't cross it to any of the newer grizzly lathes but don't rule out the older grizzly and jet machines, trouble being the manuals only give a pic and a part number and no actual dimensions so you'd just be guessing seems like to me. It's a 17t gear btw.

Hunting down something like that can be frustrating!

I'd give http://gearsmade.com/ a call. It might end up being the quickest way out. If you do, let us know how it pans out and what he charges. It could be a great resource to know about if the cost is reasonable, as I suspect it will be.

Of course there is http://www.mcmaster.com/#gears/=112wa59 and places like http://qtcgears.com/products/wormgears.php that might have it if you get lucky.

Call Grizzly. Their part P1003104 from their discontinued 12 x 37 G1003 lathe, for which I posted the link for their parts list, may be the same. It's in stock for pickup at their Missouri showroom for $14.25. Ask if it is 17 teeth and see if they'll provide you the dimensions.

Just checked and that part num is for the crossslide feed pinion, the lead screw drive worm gear is discontinued also.

Don't know if it will work for you lathe but I was able to purchase a worm and gear set from a local industrial supply house and modify the bores to fit an import band saw. You would need to maintain the number of teeth and the center distance. You got all that information at hand, include the broken and worn away teeth in the count.
