Band Saw Stripped

[Machine Man]

Hi, New to the forum. I have an older 60" Craftsman horizontal band saw. One of the aluminum gears has broken a tooth and it doesn't work right anymore. I don't imagine Sears has parts for an older machine like this. What do you think is my best option for getting it fixed?

Thanks,
Machine Man

Punch in the model number into the Sears Parts Website and see what they have and don't have for it. They have more than you'd think.

Thanks, I guess I should have tried that first. They have the big gear for $335.72. Who knew a pot metal gear would cost that much. Harbor freight has a new 64" horizontal bandsaw with stand for $249.99. Still looking for options, maybe a way to fix the gear?

Post up the model number and maybe a pic of what that damage looks like. Hard to help you without something to look at.

Post a pic and take some measurements.
Can you pull the gears and go to a pulley system?
Can you fins similar industrial gears that you could convert to?
Do you have other machine equipment or know someone that could machine a gear?
How about using that low tempature alloy for aluminum repair?

There are always options

Download a Boston Gear catalog and see if they have a stock gear with the right number of teeth, dimensions (you will need to have at least the bore machined to fit your application), and material. They will call out a pressure angle, and you might have to take the gear to a machine shop to have them determine that. Most applications used standard pressure angles.

Here is the BG web page, you will need the catalog for Rotary Drive Products:

Good luck!

contact sears, my garage door openers are ancient and parts were still available through sears!!!

Another alternative is try to find a homeshop machinist in your'e area, an aluminum gear is not too hard to make.
Have no idea how big this gear is, but many gear teeth have been replaced by leveling the broken surface, then carefully drilling and tapping two or three threads, and screwing in short studs, then filing them to shape.
Old school repairs, but they work.

A picture would be a great help. Obviously, $335.72 is pricey and I don't think I would spend that much for a single part of the saw. Looking for a machinist is not a bad idea. The damage maybe still fixable to get the saw working right.

How old? A parts machine is probably cheaper. I'm going to guess it's not Aluminum however. Probably Zamak, which looks a lot like it and is often mistaken for it.

Pics of the gear and saw would help.

Sears Model # 101.2290 I'm a HSM so I'll have to take it apart and see what I can do.

As has been suggested, I would take it to a small machine shop and inquire as to the cost to either repair the one you have, or possibly make a new one. It can't hurt to ask and you may be pleasantly surprised. If you don't like what they tell you, then you haven't really lost anything except for a little time.

I doubt a real big machine shop will want to help you with such a small job, but who knows? Maybe they aren't very busy and will be willing to do what you need done for a fairly cheap price. But I tend to think you would fair much better at a smaller machine shop. It's just a suggestion and you may not want to go that route, but I think it would be a good idea.

I have that same band saw, it's a great unit and worth fixing
I take it you broke the small bevel gear that drives the wheel or is it the wheel with the gear on it that you broke?
Remove the gear
Count the teeth
Measure the angle between the shafts to see what angle bevel gear you are looking for
Start doing a search for bevel gears and see if there is an off the shelf one available,out there. Bevel gears are used in lots of stuff and are often fairly standard

After some searching it appears that the bandsaw was made by atlas which is now owned by clausing
I was pricing parts for a craftsman lathe I had that I knew was an atlas.,priced them from sears and through atlas-clausing. The parts direct from clausing were like 40% less
Give them a call, have the craftsman model number and the part number you want.
Looks like the atlas model number is 4353

You might try eBay too, I was looking for parts for my old table saw and was surprised to see how many people were parting them out.

Old thread--just sharing a possible resource.. I needed the same gear and tonite found Shapeways. I'll post feedback on the quality of the gear when I get it.. maybe some others can benefit..

Use this as an opportunity to get a newer saw. My old Porter Cable Portaband stripped its gear a few weeks ago, so I upgraded to a 9x16 Kalamazoo.

Sorry for the crappy video quality--my IPhone 4 is not so sharp in pic/vid quality anymore for some reason. (And-I only have two hands..)

Anyway--the new gears from Shapeways showed up-quite happy.. Saw is back in action and after a lot of other saw adjustments--it works perfectly.. I actually think this saw had very little use in it's history-but will in it's future..

Looks good! You might try adjusting the belt cover/pulley to get rid of some of the chirping noise. I had a HF red 4x6 that I used and abused. You can even do coping on that saw if needed. The cylinder is a real bonus. Most modern day 4x6 saws don't have it instead they have a spring.

Thanks for the tip.. I actually made a bunch of adjustments to the saw as the alignment of the blade at rest was no where near the groove and the shutoff switch contact was way out of place.. I oiled up all the bearings and I think she's just a little noisy..

Hey hemifalcon, I have the same bandsaw. I probably ought to buy a couple of the plastic replacement gears to have on hand. Thanks for the tip.

No problemo.. I'm pretty happy and I also grabbed an extra as I thought it was a good value. Be sure you clean up the driven wheels before firing it up again if you replace the bevel gear. I found a portion of the nylon gear tooth in one of the driven wheels-my guess is that is what tore up the original gear. Just make sure everything is nice and clean!
Glad I could help someone else!
