I have an old craftsman three wheel band and I cannot keep the blade on the top wheel. when I get the blade centered on the wheel and hand turn the wheels it runns right off the top wheel, don’t suggest the snodgrass video it tells me nothing, besides he is working with a decent saw a new saw is not an option. Thanks

Is the blade running off the back or front of the wheel? The position on the wheel is far less important than the blade tracking within the usable range of the guides. Is this saw new to you or is this a problem that has occurred suddenly? Have you adjusted the tracking significantly from where it was previously? Are the tires on all three wheels tight or are they loose to the point they could easily be removed? Tires squirming around on the wheels, under the tensioned blade can cause tracking issues that can be very confounding.

I have had this saw for 20 + years, didn’t use it a lot. I started using it more, got a new Timber Wolf blade. the blade has come off before, especially when i turn the saw o n without tesioning the blade, but I have been able to get it back on. this time I can’t. It runs of the top wheel. Her is a picture of the saw

Take the top wheel off and see if the adjuster broke. It slides up and down, and pivots in and out, see if it cracked or broke. I had this happen on a band saw and it was the tensioner it was cracked and wouldn’t allow you to adjust the blade.

Sounds like either you have not properly set your tracking and it’s way off, or your tracking mechanism is bent/broken like mrg suggests. Might also want to check the condition of your tires.

Cheers,

tires appear to be ok, I don’t have the faintest idea how to adjust the traking, I noticed the the blade was not even staying in the guides it was forward of them. I

To track the blade there should be a thumb screw or knob directly behind the upper wheel below the tensioner. You turn that in very small increments to track the blade. It don’t take much. Spin the wheel by hand while making the adjustment. You will see a small turn will track it back or forth. The guides should also be adjustable on that saw. Their should be a screw or bolt you loosen and slide the guides back and forth and side to side. Get your tracking done first then adjust the guides.

It is very rare that you would be able to just grab a blade and put on the saw and it just tracks perfectly. At least in my experience you have to mess with it.

What size blade you trying to put on width wise. Also the length if it is to long won’t tighten properly. Do you have a Sears by you? If so go to Sears and get a blade from them and see if it makes a difference. They are fairly inexpensive.

The tracking should be the knob on the back that tilts the tire side to side I believe. If it doesn’t have one, maybe your tires need balancing if something broke off?

Well… there is your problem.

Get a manual for the saw and read it. You will be amazed at all the stuff it can tell you :)

Cheers,
Brad
