Thread: The wobbles

G'day Doug

When you say the whole bandsaw wobbles, does that literally mean the whole saw wobbles or just the blade?

The Blade I'd understand but the whole machine, hmm

I'm local to your area, so can drop in and sticky beak your problem and possibly offer advice.

Sounds like one of your wheels needs balancing

Thanks for the tips. The wheels seem to be balanced using the roullette method...give it a spin and see where it stops...consistant resting spot indicates a problem? The method theoretically is a good one but I'm in the shed and the books are in the house Is there a more practical yet accurate way to do it, perhaps with the saw running. I aligned the wheels as well but this just made the blade run dangerously close to the edge of the tyre on the bottom wheel which makes me think the tyres are stuffed. I put everything back where I found it so the blade runs safely in the middle of both tyres.Then I thought maybe the motor and drive pully were fighting each other. Sure enough they were well out of alignment. Fixing this made a big difference to the wobble.

Love to hear about other things to try

Doug

I would take a close look at the bearings, may be one trying to tell
you something.

Is this saw bolted down or just sitting on the floor? If it is not bolted down I can see a problem like this occuring if one of the wheels is only slightly out of balance. It starts as a mild movement, gets rapidly worse and then stops for some reason. I bet the reason is something to do with the frequency of the wobble, but I'm not an engineer so can't tell you why.

I've seen that happen before but it was so long ago I don't recall the precise outcome.
So I'll take a couple of guesses.
1. Wheel balance
2. A tyre is slipping on a wheel under load.
