First and foremost, unplug the bandsaw before you do anything else.
Test the wheel bearings, as recommended by @woodnthings
. If one of the wheel bearings has gone bad and is the source of the squealing, then maybe @SomeDudeOnline
will need help. Personally, I would try to replace the bearings myself. I have not done it myself, but it can't be that difficult. Many many people have done it on their own. SomeDude has little to lose by trying.
My guess is that the wheel bearings are fine.
If I were @SomeDudeOnline
, I would replace the tires on the bandsaw wheels myself. It is a skill he needs to learn anyway. No matter the root cause of the problem, at least one tire must be replaced, but I would replace both of them now. Bandsaw tires are not expensive, especially compared with paying someone to do such a basic job. This is the perfect "take it on and do it myself" job, and then he will know how to do it for the next time.
Does SomeDude know how to install a blade and adjust the bearings, guides, and tracking for it? It can be tricky for a beginner, you know. I started to write a full set of instructions on how to adjust a bandsaw for a blade, but gave up and deleted it. SomeDude has the user manual for his bandsaw, and there is so much information on the internet, including plenty of YouTube videos to watch.
I wonder whether the squealing is caused by a frozen bearing, or maybe the blade guide bearings or guide blocks are poorly adjusted. Frozen bearings are common - the sawdust eventually gets in and destroys the bearing. If the bearing shows any
resistance to turning, replace it. If the bearing doesn't turn, then the blade rubs and wears against the same spot in the bearing, generating unwanted heat, and maybe loud squeals, too.
My 1953 (14 inch) Delta 890 bandsaw makes a squealing noise when I am cutting, and especially if I attempt too tight a curve with the current blade. That's normal. My bandsaw is very quiet when it is turned on, but I am not actively cutting wood on it.
Finally, my local woodworking club has "mentors" who are willing to help members in various woodworking areas. They have a bandsaw mentor. I was already a member of the club when I bought my used bandsaw. I called the bandsaw mentor, and he helped me check it out carefully to make sure it was safe to operate. He gave me safety instructions, and finally taught me how to handle blades, install them, and adjust the saw accordingly. We made a few cuts to try it out. I offered to buy him lunch to thank him for his time, but he had places to go.
That's what SomeDude needs, a friend with bandsaw experience who can stand by his side while he learns how to replace the tire, check out the saw, and teach him how to replace blades, adjust it, and use it
. In my opinion, SomeDude should not haul his bandsaw to a shop full of strangers who will charge him a fortune. If he does that, he won't learn much for the future, will he? As I said, I would check out the local woodworking club before I would search for a shop. Let see: Save money, learn more, and make a friend. Who wouldn't appreciate that?
I like the woodworking club idea the best, but SomeDude might think about bringing his bandsaw one of the local woodworking shops. If he lives in an urban area like most people in California, there should be a Rockler or a Woodcraft or another woodworking store near him. I would definitely call first before showing up with a bandsaw. They may not be interested in helping, or they may not have the time. Or they may be nice and say, "Bring it in and we'll check it out briefly." Don't expect them to be patient or do a thorough job. They may also offer a beginner bandsaw class. Both Rockler and Woodcraft offer them. You could ask whether you can bring your own bandsaw if you take the class.
