Like many of you, I've been taking the extra time at home during covid to go through my storage and get organized and clear stuff out. In doing that I had to make the call on an old Craftsman bandsaw I've had in my basement awhile. It was a 103.24260 from the '60's I picked up years ago along with a drill press for about $75. I prefer the aesthetics of the earlier style bandsaws from the '50's, and so I'd never really done anything with the saw.
I decided to keep the saw and put it in use until I could get an earlier style saw to replace it. I suspected, but was not positive, that the earlier style saws had the exact same foot size and placement. So if I built a nice stand for this saw it would also work for the earlier style as well.
The saw did not have a base and the old motor that came with it was in very rough shape. So I decided to toss the motor and engineer a solution to give me the ability to slow the saw down for cutting metal (typically 100-300 fpm blade speed) and while also still able to cut wood at faster speeds (2,000-3,000 fpm blade speed). So I kept an eye out on Craigslist and found a guy selling a SEW Eurodrive 1/2 hp three phase gear reduction motor for a good price. The gear reduction takes the 1680 rpm motor speed and reduces it to 164 rpm (and multiplying the effective torque of the motor) for a good starting speed. Additionally, running the motor on a variable frequency drive (VFD) would allow me to plug it into 110v and have additional speed variability from 0 - 328 rpm on the shaft by running up to 120 hrz frequency. This motor, combined with 1"-4" drive pulleys on both the motor and the saw, will give me a blade speed range of sub 100 fpm up to over 4,000 fpm.
