hello I own a 12 inch craftsman band saw 113.24350 and its dying pretty fast I got most vibration out of it with a new pulley on lower wheel all bearing are good and when I just run the motor I get NO vibration at all and right now I just cant afford a new saw and most on craigslist are a ridiculous price or the owner is a joke any way my question is do you guys think it would work to put plywood in between body of saw and stand ??yes I checked all bolts are tight :<))

this would require me too get a longer belt …then should I get a link belt …or just keep nursing it till I can afford a new one ..or a good craigslist find ?
THANKS ALL :<))

Adding weight helps, but if the vibration is excessive, then you really need to narrow it down… tires, wheels, bearings, belt, pulley, etc… you have already eliminated the motor as a suspect. How bad is the vibration anyway?

I have that same saw Tony and mine vibrates more than I would like as well. At least in my case, the slots where the motor mounts to the base are pretty long, and I have my motor fully down in the slots. I think I could easily add a layer of 3/4” ply to mine and not have to change the belt, just move the motor up in the slots. Have you checked where you are in the slots? You might have room too.

I also found that mine runs much smoother if I carefully align the motor pulley with the pulley on the lower shaft using a straight edge. The slot arrangement where the motor mounts allows adjustment up and down as well as left to right, but that also means you can get the motor tilted such that the shafts are no longer parallel. at least for me, that created vibration.

Agree with Brian. The link belt may help, too.

Ok, so you have eliminated bearings, pulley, motor and wheel shaft. That leaves basically the belt and tires/wheels/blade. I can’t imagine a belt causing that much vibration… that is usually caused by belt set from sitting an extended period of time, but it will go away after a few minutes of using the machine as the belt warms up (and would not cause really excessive vibration anyway – at least not enough to make the floor shake :) I’d look at the tires/wheels/blade. Do you have a dial indicator? If so, measure the wheel/tire run-out to see if it’s way out. If you don’t have a dial indicator, you can improvise with a stick clamped in position and visually watching it while spinning the wheels. Check them for balance as well – an out of balance wheel can cause a lot of vibration. Check the tires for obvious damage. If they are the original rubber tires, you can true them up pretty easily. Watch the blade as it’s running to verity you don’t have a kink or bad weld. Keep narrowing it down!

Cheers,
Brad

Not sure where I read it, and unfortunately because of my penchant for reading, I will not read more than I need, so I’ll take a sabbatical in trying to find it. However, the article went on to talk about “buckling” in the top bandwheel often attributed to not releasing the tension between use (especially in the smaller bandsaws – 14” er).

I’m no engineer and in my layman’s opinion, a ply insert might dampen the vibration but will not fix the cause. It seems like you have checked most viable options so try the wheel trueness (if not already done). How do you check it…. hmmm… je ne sais pas, you might need to rtfm.

Failing that… good luck and save your penies for a new/pre-loved bandsaw.

I used to have the very same saw, and a link belt did indeed cut down on the vibration. I’d try that. The HF one is ~$30 with a 20% off coupon.

Take the blade off and run it, if there is no vibration then it is either tire related or upper wheel related.

IF mine isn’t sitting with all four feet planted firmly on the floor, there will be a bit of vibration, ...

I had the saw apart for a while ( new tires. ) While the tires were off the wheels, I cleaned the beds on the wheel where the tires would sit….there was a LOT of caked dust stuck under the old tires. While the lower wheel was spinning under no load, an old file was held to the wheel. Vibration in the wheel soon disappeared.

Instead of plywood between the saw and the base, maybe just enclose the base, to keep it’s legs solid. Maybe add a screened vent for the motor? Find some of those old faucet washers, install them between the saw and the base.
