Don't you have an old blade which worked correctly before you had the problem?
The wheels should not rock at all on a bandsaw.
I have an 18 inch bandsaw and I can change my blades in about 15 minutes. It takes about 3 minutes to get the old blade off. Then it takes 3 minutes to get the new blade on and about 10 minutes to setup the guides if changing blade sizes.
When you change blades sizes make sure the bottom guides and top guides are setup for right below the gullet of the blade and they don't rub unless force is added. I find the guides need to be adjusted when I change blade sizes.[/QU
Lee I agree with you on resetting the guides every time you change blades. I just put on a 3/16" blade and it is running true from left to right but there is a little movement forward and backward. I am going to order another 1/2" blade because I think it must be the blade.
The two nuts with the socket head bolts is something I don't understand. Do you know what they are for and how they should be adjusted?
