I recently purchased..( ok traded ..) for a Craftsman 12 inch bandsaw.It came with a `1/4 inch blade which was fine at first..now I stopped by and picked up a 1/2 inch blade because I need to do some more sawing,but with a bit more stable cut.I installed the blade…back off of the bearings to make sure nothing is touching the blade and SLOWLY rotate the balde without the power being on.Now I noticed the blade keeps walking off of the wheels.I checked the tension adjuster and its right on the correct tension.Now this bandsaw came with NO booklet…( what do ya want for free…? lol..) but I dont believe it can be that hard to replace one blade with a wider one…ok I was wrong. Now I did notice..( if it means anything..) that the lower wheel has rubber around the wheel but the upper one doesnt..( make sense..? ).Could I be doing something wrong..? Think the wheels need to be replaced.?As always..any HELP is good help….Thx.

Unless Sears has a new-fangled design, the upper wheel should probably also have a tire on it. You should also be able to adjust the tracking to keep the blade on the wheels. This is done by adjusting the caster of the top wheel to control the track of the blade. I don’t have a Craftsman saw but check on the back side of the saw just below the center of the upper wheel. There may be a small adjuster (usually with a lock nut of some sort on it) to make the adjustment.

Check carterproducts.com. In addition to some really slick bandsaw upgrades, they have some useful information on bandsaws (and other tools).

Whit is right on!

WIthout a belt on both wheels, do not plug this machine in! The upper tracking adjustment should be the same as most similar machines. Go to one of thier websites and view/download a manual ASAP and go throught the adjustment procedure. I have no doubt that Sears online can help you as well. You will likely enjoy this tool once it is set up correctly, but there needs to be a belt on both wheel first.

I have a older craftsman 12in bandsaw and I was having a problem with the tires comming off the wheel so I took them off. It works fine with out them. If yours is like mine, there is no tracking devise.

Have your say...
