This is my 1952 Craftsman 12” Band Saw. She has been soo unrealiable over the years and i was on the verge of tossing her out. BUT- i figured to give it a go and see what she can do when everything is tuned up and running smooth. Did some research and reading, found out that although this saw is old and relatively small (12”) she was able to hold her own back in the day.
New thrust bearings (stainless steel pulleys work in place)
New solid base.
New belt, new shaft pulleys.
The rubber for wheels were Ok but needed glued down. This saw really hasnt seen alot of use thro the yrs.
attached are pics: Im asking the expierenced LJ’s for some help. The saw vibrates not alot, but little too much to know somethings off. And the blade speed is fairly slow. The motor spindle pulley is a 2”, and in the pics my drive wheel pulley is 4”.
Since im using an automotive 1/2” belt, its fairly rigid and doesnt seem to like the sharp curve of making the tiny 2” motor pulley. And since the 2inch pully is small, the belt has less area to grab onto. (slipping)
Question is- Should i buy a 3, maybe 3 1/2, possibly a 4” pulley for main motor spindle? If doing that, i would prolly also have to increase the pulley size of the wheel pulley (but how big etc…) whats your thoughts on this. Any help is always appreciated.
Using a 5amp motor, 1750rpm. 1/3HP.
FYI- the wheels are balanced, all nuts,bolts are tight. I designed the motor to mount on a 2”x6” solid chunk of Maple. Its on hinges and the weight of motor is what gives tension. I also added rubber matting and bushings where needed to eliminate vibration.
any tips…? Thanks JAMES LANGO
