Topic tags/keywords: question help bandsaw

So, I recently acquired an old AMT (Taiwanese Delta knock off) 14” bandsaw on the cheap and I just bought a new blade for it yesterday. Got it on and can’t seem to get the bottom wheel to track properly. The top tracks fine down the center, but the on the bottom, the blade tracks all the way to the front of the tire to where it slips off within a oupe of seconds of tuning it on.I believe I have the tension adjusted properly, and I backed off on all of the guides. It came with a 3/8” or 1/2” 14TPI blade, i bought a 1/4” 6TPI blade for cutting some curves in the oak feet or my workbench project. The case on the saw says 92.5” max blade, I put on a 93.5” blade as it is more readily available and I have read on the SMC forums of others doing the same. On a possibly related note, if I turn the wheels backward, the blade seems to track fine on the bottom wheel…

Any help or suggestions would be greatly appreciated, as it is the weekend (my woodshop time) and this debacle has thwarted my plans to finish my new workbench… I will try to answer any other questions or provide more details if needed, thanks,

-Chris

Just a guess….Try looking at the coplaner of the upper and lower wheel. A long straight edge placed along both wheels. Straight edge should full contact with each wheel. If not, adjust the upper wheel until in alignment…good luck

If you can take the table off it may make it easier to check to make sure the wheels are in the same plane with a straightedge. You need to adjust so that a long straightedge will touch both wheels in two places (four points total contact). Wheels not in alignment are the reason the blade comes off so fast, but you should also check the rubber/urethane covering the wheels – if it’s worn unevenly that can cause tracking problems.

Edit: You say you’ve got a slightly longer blade on it – you are still able to get it tight right? Tight as in the blade rings and there’s only a bit of flex and you still have room on the tensioner, you haven’t maxed it out? A loose blade will never stay on, no matter how perfectly aligned the wheels are.

Ordering new tires, these were fairly worn.
Will check if wheels are coplaner tonight.
Tensioner not maxed out. Gets pretty tight.
Going to get back at after the kids go to bed..

I would try the blade size that it suggests. I order from Hal Taylor, www.buyfromawoodworker.com

It is possible for the lower wheel to be off; I’ve seen it happen. Everybody assumes problems are due to the top wheel, because it’s adjustable. If nothing else works, see if it’s possible to tweak the bottom wheel, maybe shim it a little.

Have your say...
