Source for gears for OLD horizontal bandsaw

[67King]

I bought this horizontal bandsaw probably 12 years ago.......and the shaft on the worm gear broke after I sectioned about 2 cylinder heads. And the worm gear itself is almost gone, completely. And it has been sitting since. At any rate, I would like to get this thing going again. It was ancient when I bought it. I have not been able to find a source for parts, and admittedly it is becauase I just do not know where to look for this kind of stuff (I tried Grainger at one point). ANy of y'all know where I should look for stuff to get this thing up and running, again?

Side note......it wasn't that dirty when it happened, I left thhe cover off and haven't replaced it.

Make and model would definitely help to at least narrow down what you'll need. Have you tried McMaster Carr?

You need to do a search based on the make and model.
I had a China made bandsaw I bought used and then used the hell out of it.
The gears went out like yours so I figured one China made bandsaw is the same as all the others. Not true.
The gears I ordered for the thing were off enough that that would not work and would not have been an easy modification.
The saw I had was a 'house brand' and they were not supporting anything on them any longer and could/would not tell me where the sourced the saw in the first place.

Crud, forgot that. Dayton 3Z093S. Not much info out there that I could find.

Contact Boston Gear. You'll need to know the OD, the ID of the center hole, the tooth count and the pitch of the driven gear. They found one for mine and I had to have a machinist broach a keyway but it fit perfectly.

Contact Boston Gear.

You'll be able to buy a Chinese saw twice over for what they'll charge for that gear

Check on owwm.org (Old World Woodworking Machines), or Vintage Machinery. Someone there may have the part or be able to point you in the right direction. The site was VERY helpful when I restored a Delta wood/metal bandsaw recently. Good luck

Don't bother, they don't do Asian there!

Dayton is WW Grainger. Did you check with them?

Toss it and buy a new (used) saw. Lots of them out there for next to nothing prices. I bought a USA-made Kalamazoo a few months ago for $200, so just keep your eyes open.

McMaster has some, SDP-SI has a decent selection. You won't find the EXACT match for those, but all you need is a matching set. You might only need the worm....which could be made on a mill with horizontal rotary table.

What's the function of the gears, to close the vice?

Grainger was the first place I went, but again, that was at least 12 years ago. The saw, itself is probably 40-50 years old, and is US made. I bought it (used) from a friend's father. I could try the local Grainger, but the one in Dearborn had some really sharp guys there. I haven't had much luck here in the past, and when I went there many years ago, they wouldn't recognize my account (which the one in Dearborn set up for Ford employees' personal use), and consequently wouldn't sell me what I was after.

The part that actually broke is the shaft that runs from the pulley to the worm (shaft is easy, McMaster-Carr has those). But the worm is also obviously quite worn. The motor is connected to a belt, which is connected to said pulley, which drives the worm. The gearing turns the system 90 degrees (and also reduces speed) to drive the wheel to which the blade attaches. Both gears are located by teh case, so if I were to change both gears, I would have to be certain that the spacing and offset would match......which would almost certainly lead me back to an identical set of gears.


McMaster does not have a matching gear.

Well if it truly is USA made, ask over at OWWM. I still have my doubts, but I've been wrong before. Can we get a better pic of the whole saw? Grainger/Dayton must have sourced that somewhere, maybe somebody will recognize it.

When did they start making stuff in Asia? Surprised there is doubt about a half century old saw being made here. Nevertheless, here are some labels. Dayton label technically does not say "Made in USA," although the GE label on the motor does. All of the fasteners (including small internal drive set screws) are standard.

I am going off of memory, but I'm pretty sure the guy I bought it from built the stand w/ dollies for it, as well as the automatic cutoff. So it probably doesn't look like it did when it was new. But the body of the thing should.

Metal-cutting bandsaws generally have a worm-drive gear reduction box to cut the sfpm down to a reasonable value. Metal needs 80-200 sfpm, while wood is around 4,000 sfpm IIRC.

I agree it could be USA-made, but it's too bad that the gearbox was not a separate unit bolted onto the frame. That would have made it much easier to retrofit a complete new gearbox. Again, I will reiterate that it would be easier & cheaper to buy another saw.

The gearboxes are a few hundred bucks, which would absolutely make it easier to just buy another one. Shaft is $20. The wrong worms are about $30. If I could fix this one for $50, I'd do that. But at the end of the day, you may be right. I'd rather find out before assuming, though, you know?

Do appreciate everyone's input.

You might be surprised. Boston told me the gear I needed but they don't sell direct. Got the gear from Amazon for $60 and spent $20 having a keyway broached. Mine was also a USA made horizontal bandsaw and I felt it was worth rebuilding. I couldn't buy a brand new HF saw for what I have into mine.

This it?

Or have a look here:

If the one from the Aus website turns out to be the right one, PM me if you want a hand getting one

Your Dayton looks identical to my Asian made Porsche (yes I have a Porsche bandsaw )
