Hello again John,
You were able to help greatly with my jointer issues, so now I have a similar bandsaw question… For my ‘salvaged tool shop.’
Basically, I have a solid old bandsaw, with a similar issue as the jointer.. It bogs down when I doing any resawing of any kind… I know for a fact that the motor itself IS bogging down, the belt is not slipping. If possible, I would like to get this one tuned up to the point where it can resaw, cut cabriole legs, and the like… Any suggestions?
If you see purchasing a new bandsaw as a better solution, do you have any recommendations in the quality home shop types?
thanks much,
Mike

Mike,
To give you a good answer I need to know the make and model number of your saw and the horsepower of the motor. The usual cause of problems with sawing on a band saw is having the wrong blade on the saw typically compounded by the blade being dull. 90% of the time a new, sharp, appropriate blade will solve sawing problems, but let me know what more about the saw and the motor in case there is a problem there.

Hello John,
In the busy holiday season, I have been delayed in getting back to figuring out the bandsaw issues. Now, I've collected the information you need.The bandsaw is an off-brand - CII Model: BP-VBS-14. 14" vertical wood cutting bandsaw (as is reads on the face plate).There is a 3/4 hp motor. 1710 RPM. 2 5/8 inch motor pulley, 5 7/8 inch wheel pulley, 13.5 bandsaw wheels. It takes a 92" blade. The blade is fairly new, but was just a cheap one from Menards.Please help!thanks,
Mike
Mike,It is nearly impossible to stall a 3/4 horsepower motor properly hooked up to a band saw. I suspect that the fault is with the motor. A 1710 RPM motor is an oddball, it is most likely salvaged from some other special application and not wired up properly. What does the motor's nameplate say on it for voltage and frequency and the like? Are you in the U.S.?Is the saw a copy of the cast iron framed Delta 14" saw that several companies are now making in Asia? For that matter where was the saw made and what is the manufacturer's name?John W.
Good evening John, hope you are having a good new year.There is not terribly much on the bandsaw. The plate on the body of the saw read (exactly):
A logo of 'CII,' Model BP-VBS-14, 14" Vertical, Capacity 14x14, Blade 92"L, Motor 3/4HP 1PH, Serial 8512531The plate on the motor reads:
TY Induction Motor, HP 3/4, Phase 1, Poles 4, Temprise 40 C, Volts 110/220, Cycles 60, Amp 7/3.5, RPM 1710.That is every last word that is on the machine. I picked up this machine on Craigslist about a year ago, assuming that a 3/4 hp, 14" machine would do what I needed...but something must be wrong. I am in Northern Minnesota, US.thanks much for you help, talk soon

Mike,Check that the motor is wired properly, if the connections in the wiring box on the motor are set up for 220 volts and you are plugged into 110 you would have very little power. There should be a little diagram on the motor's nameplate or glued onto the inside of the motor's junction box cover that will give you the proper hookup for the wiring. Also get a blade meant for resawing, something 1/2 inch wide with just two or three teeth per inch. I've always had good luck with the Timberwolf blades from Suffolk machinery. Get several blades, they don't last long.Also make sure the pulleys are lined up properly and the belt is in good condition. The pulley sizes sound like they are appropriate for a 3,450 RPM motor, which is what is commonly used for band saws, so you are possibly running at a slower than normal speed which would make for slower cutting but more torque so the motor would be less likely to be bogging down.Don't do anything with the pulleys right now I need to make a calculation to see if I'm right about the blade speed.John W.
A 1,700 RPM motor is the correct type for your saw, so that isn't the problem.John W.
John,
I have taken apart the electric part of the motor... When I have done this in the past, I have had instructions... Unfortunately, this time, there are no instructions or diagrams anywhere.. So I am not sure how to rewire and make sure it is for 120...Any ideas?thanks,
Mike
Evening John,
I wonder if I should send you a picture or send a diagram of what I am seeing, how the wiring is set up now...??Mike
Sure, but I need the information on the plate or the box cover that shows the proper hook up also.John W.
Hey John,
Unfortunately, there is no diagram of any kind... Not anywhere on the body or on the plate.What to do?thanks,
Mike
Hello John,
I've drawn and attached a simple diagram attempting to illustrate the wiring on the electric motor of the bandsaw. Unfortunately, there are no instructions on the bandsaw to help with this wiring.Can you offer any help?thanks again John,
Mike
Mike,I'm stuck at this point, there is no standard way that the leads in a motor are organized, so without a diagram I'm clueless. Your best bet would be to take the motor to an electric motor repair shop and have them figure it out, they can also check for other faults at the same time. Sorry I can't be of more help with this.John W.
Hello John,
I did bring the motor to a local electric shop, and they said that it was wired for 120. At this point, it would seem there must be something wrong with the motor... I am either going to purchase a new motor (I was thinking perhaps from Grizzly industrial), or I may put on a 2hp motor I have. However, the RPM on the 2hp is 3450. Would I be able to make that work with new size pulleys? What sizes?Thanks John
Mike
Morning John,
Last night, I purchased a new Dayton 3/4hp motor, and spent some time getting everything hooked up and tuned. I can finally cut 6 inch stock with no problem!!!I ordered some Timberwolf blades. Hopefully that will reduce some of the noise, because when I was cutting last night, it was excruciatingly loud and screechy.Do you know of anywhere that I might order parts for a bandsaw from? The part that connects to the post that you use to raise and lower the blade guide has a small crack in it. I also should probably replace the rubber tire material on the wheels of the bandsaw.So, thank you! It took some time, but I was even able to easily cut through some tropical hardwoods with no problem..Mike
