Well, I took a different and somewhat more comical approach with my Toolkraft (of Springfield, Massachusetts) 14" bandsaw. I used pulleys.
This what I posted somewhere at the time:
The saw in the first picture is a ToolKraft 14" Wood/Metal bandsaw. It was in good working order and clean when I bought it for $85.00. It doesn't look like it was ever used very much. It seems to be a copy more or less of the Delta Rockwell 28-200. Toolkraft was headquartered in Springfield and had a smaller plant in Enfield CT. It closed in 1984. This saw was made in Enfield.
I don't have a picture of the top pulley. Originally there was one belt that ran from the motor to the pulley running the wheels. That ran too fast to cut steel.
I added the large pulley and replaced the cone pulley on the motor with a 1 3/4" pulley, which was the smallest I could find. I created an Excel spreadsheet with the necessary formulas then ran it for different size pulleys. I got it down to 118 feet per minute.
I made an aluminum shaft from an old GP small pole. I mounted it through four brass bushings I had on hand. I made a support out of two pieces of 2"X4". About the largest wheel I could use was 10". To get the smallest diameter to drive the belt going to the saw I used the 3/4" shaft itself. The belt going to the saw runs between two additional bushings that each have two set screws...The 2"X4" supports are in turn supported by a cross piece I installed. I made it from a piece of iron bed frame. I have it attached to the saw frame with one bolt on each side. These are set up to provide tension adjustment to the second belt.
