Modifying band saw – 2 hp motor – how to
I am starting a new thread to share the “how-to” I learned and applied successfully from another thread. Two photos are attached.
I replaced the ¾ hp motor in my enclosed stand Delta Bandsaw with a 2 hp motor. The first thing I learnt when the new motor arrived (not from Delta) is that even though I ordered a motor of the same “frame”, it is about 2.5 inches longer. Apparently, this is the way motors are specified – you have to pay attention to other dimensions. I could not find a 2 hp motor of the same physical dimensions.
The motor looked like it just about fit “in space” in the enclosed cabinet. So then it became a problem of seeing how to get the pulleys and the belt in the right location. In the end, it turned out to be straightforward. Here are the steps, in case anyone is interested:
1. Turn the struts the motor hangs from around 180 degrees. Mount the motor. It turns out that coincidentally, or by design intent, the mounting holes in the struts now position the motor (at least the one I have) so that it is entirely within the cabinet and with acceptable clearances.
2. Now the opening in the top of the cabinet base has to be enlarged because the belt is going to be much closer to the side wall of the cabinet base. I found I had to enlarge the opening by ¾ inch, and that gave me about ½ inch of clearance beyond the belt. (Note, the pulley on the motor shaft has to be turned around, and the clearance between the belt and the body of the motor is about ¼ inch in the new position). A new 24-point blade in my jigsaw did the job easily. In the attached photo, you can tell the section that was removed by the not-so-great cutting job.
3. Undo the bolts that attach the bandsaw to the cabinet (I had actually taken mine off earlier).
4. Slide the band saw over. I had to turn the pulley on the shaft in the bandsaw around too.
5. Get everything aligned (pulleys, belt, bandsaw etc.) locate where the holes need to be for the new position of the band saw.
6. I simply drilled 1/8” oversize holes in the 1/8” steel, in four steps, even though the original holes are elongated. They worked fine
7. Mount everything, fasten.
8. Install the belt guard in new location, drilling appropriate holes. It turns out that the outside face of the belt guard just about lines up with the sidewall of the cabinet base.
As a point of interest, the band saw is now located nearer to center on the base. The original mounting had it off much more to one side. The second photo shows this.
This is the short version and assumes that if you are attempting this operation, you can figure out the other stuff. My thanks to all the people who contributed and shared suggestions in the original thread, particularly TDKPE.
