Bandsaw tire problem.

Greetings,

I’ve got a issue with my new bandsaw tire, Urethane Band Saw Tire.

It doesn’t fit my Delta bandsaw width.

Notice the gap? Should the gap be at the front or back side of the wheel?

With the gap at the back, the blade has jumped off of what I had it aligned to. Ruined a new blade on the steel guard. I couldn’t shut ir off fast enough. Sad.

I bought it from a noted site and have purchased things there before with no problems. The box that the blade came in. said it was for a Delta 14”, which is what I have.

But this appears not to fit.

I do not truly know, as I have no experience with urethane tires yet. Having said that, I’d be tempted to center the tires on the wheel, unless they easily slide front to rear…

Can you cut a thin strip off of your old tires to fill the gap? Have you reported the problem to the company?

I do not have a delta bandsaw, but here is a link to the bandsawtires.org, that may give you some help.

Opps, I forgot to tell you that I only bought ONE tire.

I’ve just ordered an second tire for the top wheel.

They’ve told me that the urethane tires are flat. NO CROWN.

Now waiting until it gets here.

I just put urethane tires on my old delta 14” bandsaw. They do have a crown, and were about 1” wide, fitting with no gaps at all. They’ve been working really well so far. How wide are your new tires, and how wide is the gap?

I understand that Carter tires are only 7/8” wide, while the Delta 14” requires a 1” wide belt. It may be the differences between manufacturers. I suggest that you buy the proper width.

I don’t own a delta, but in looking for new tires for mine I did see different widths for the 14” and I “think” the delta may have made some 14” models that took both.

i dont know exactly how much of a gap youve got, but I seem to remember having somewhat smaller tires than wheels on my bandsaw with a similar sized gap. I didn’t give it much though – once the blade was tracking right it always ran along the center.

I have a Delta Homecraft 10”er that I just put new tires on recently. The wheels on the bandsaw looked just like yours with a raised lip around both front and back edge of the wheels. The tires were perfectly flat but the wheels had a crown. When I installed the new tires they conformed to the wheel and had a crown.

If you are throwing blades, then I suspect you don’t have the bandsaw adjusted right. There is plenty of tire there if the tire is not moving on the wheel. I would get the right width tire though.

Wheel alignment must be checked with a blade installed and tensioned because the load will distort the saw frame. This can be as much as 3/32” at the top of the wheel when a ½” blade is installed on a saw with a riser block.

Check wheel alignment with a long straight edge held vertically against the rims. Tilt the top wheel until both wheels are parallel vertically. There is an adjustment for this.

I would suggest you turn the wheel slowly by hand first to make sure the blade is centered. Then spin it faster. Finally, turn the power on and off quickly to be sure it stays straight. Might be a good idea to use an old blade to check it with first, too.

Hey guys,

They’ve told me there is a CROWN in the tire, but notice the sawdust in the center of the tire. Odd, I see a crown.

I’ve used the saw to cut a couple of curved parts, and no problem.

But today, it wants to jump froward at least 1/4”.

I don’t feel the tire is thick enough and therefore, the blade is touching the rim.

OK, maybe I’m doing something wrong, but I don’t think so. I’ve set-up several blades with no problems.

Why now. The only difference it the tire, but I have made cuts for a while/several days.

I have the same blue tires on my Delta 14 inch saw –
I just centered the tire and center the blade on the tire. the tires have a crown and so the position of the blade on the tire controls your tracking – - the position on the wheel (within reason is irrelevant). The wheels are coplanar – but there is always some difference – but the focus is to have the blade centered on the top tire since that is where your blade “comes from” when it hits the workpiece -

I found it highly annoying that the tires don’t fit the wheel- but there hasn’t been a performance problem over the past 3 years.

From the photo – the sawdust track is in the center of the wheel – but not the center of teh tire

yeah ive had the same problem, i cant remember how i centered the tires, but they were either towards the front or back. probably wherever the extra tire was needed is what i did

I have a craftsman and use the carter tire. I centered the tire on the wheel, by eye. The tires do have a crown. However I think it flattens out, some what, as you put tension on the blade. As far as the saw dust on the tire goes, could it be from between the teeth. And, now I could be wrong but, as your band saw is running and your cutting some wood you are creating saw dust inside the cabinet. That dust will lay on the tire even as it turns. Remember the blade does not go all the way around the tire, leaving some exposed areas. As the blade gets used it heats up which will transfer heat to the tire making it a little softer. Then as the blade continues to turn it will press the saw dust into the tire, of course not permanently. Mine does the same thing. I’ve had the same urethane tires on now for over 3 years. If your having problems with the blade walking off the tire, then I would suggest following EENGINEERS advise about re-aligning them. But I would replace both tires at the same time.

Aldente,

The blade is 3/4” and the teeth are not anywhere near the center.

I am beginning to think, since the tire is not as thick, thus allowing the teeth to bite the rim and ride up and forward.

Had it running last night and after about 15 seconds, motor running, it jumped forward.

Rubber tires being thicker allow the teeth to ride even with the rim.
