Need help finding a part

I’ve got a Jet table saw (model JWTS-10CW) from 1997 (different than the JWTS-10). The other day the hand crank stopped bringing the blade below the table. When they took it apart, I discovered that the worm gear of the hand crank had tunneled out a groove in the arbor bracket teeth (see pictures).

Everything else is in perfect shape and I’d hate to replace the whole set up if I don’t have to. I talked to JET and unfortunately, this is a discontinued part. The part number is 200059, though it appears to be the same as 200099.

I can’t find it online, and I don’t think it is repairable. So, I was hoping someone here may have an old 10CW that they would part out, or know where I might find one. Can anyone help? Thank you!

That looks like the kind of project Keith Rucker of Vintage Machinery would do by brazing over the bad teeth and recutting them. Know any amateur machinists willing to take a try?

I know the arbor assemblies on the Jet 3HP saws are pretty much the same over the last 20 years.

I think it would be worth a try take a chance and order the newer part, good chance it will fit.

Try checking with repair places that have been repairing Jet equipment for a long time. When I rebuilt my Makita 2040 planer they hadn't been made for twenty years. I found a repair place in North or South Carolina that was the oldest Makita repair facility in the US. They had a set of slow feed gears left on the shelf and sold them to me for the 1980 price list price. It's worth looking around.

Thanks everyone. Unfortunately, the pricing I’m getting from people around me is ~$400 to braze and repair the teeth. For that price I’d just get another saw.

I talked to jet and they made this model/part obsolete so I’m out of luck there.

I’m also having difficulty finding any shops which do repairs for Jet (though I do get a lot of search results for airplane repair shops). Would anyone know of a shop that does Jet repairs, general repairs, or just a big machine tool repair shop (preferably in New England). Thank you all!

Keep searching eBay and google. I was looking for blade guides for my Porter Cable jigsaw which is about 40+ years old and the part is discontinued. I found a pair twice now. one Was a complete jigsaw that I got cheap enough. The other was a little repair shop that popped up on a google search that had a pair in stock.

Give brazing new gear tips on a try. They look like they are slightly angled, but regular shaped teeth.
What came to my mind immediately was to use a Harbor Freight chain saw sharpener to grind the new teeth uniformly. It's adjustable for angle and depth, exactly what you need. I'm no machinist, but I dabble in DIY projects like this occasionally when I "rescue" some old iron. An actual machinist, could probably offer a less expensive repair than your first quote. I'd shop around, but I know all the local machine shops around here are pretty swamped with work. Show up in person with your part in hand and start a conversation with the boss or the manager who may be able to put someone on it. Another idea is a college welding or machine shop where students are always anxious to try their new skills. My son took Automotive Technology at a community college and he "aced" all the classes. Check that out as well.

I recently watched a You Tube video on brazing on new teeth, then hand filing them. to shape.Can't recall which of these it was:

Next time, lubricate your saw, at least once a year.

I use Johnson's Paste Wax on the gears and ways of my saw because it develops a hard crust that minimizes saw dust collection, but breaks up easily when the gears are moved. For me, and my 70 years of woodworking, it has been the ideal lubrication for woodworking equipment gears and ways (trunnions).

I think the saw must have been designed poorly or used inferior metal to make the gear for it to wear out this soon. Most of the machinery I have was made in the early 1970's or older and none of them show wear like that.
