Step 8: Motor, Bracket, and Catch 22
I needed a motor to drive the press, and the manual gave me the specs. Went onto Craigslist and found one with those specs right away, very lucky! I went down, checked it out, and it ran perfectly. Its a Packard, which is an old name, but I have no idea how old the motor itself is. It came with a solid looking bracket and I took it home for 5 bucks. Great deal!
The bracket was not meant for the press, and the press did not have a bracket for a motor. In order to manufacture a bracket I needed the drill press, and in order to have the drill press I needed the bracket. The only thing for it was to make the existing bracket work on the press temporarily until I can come up with something better. I decided to reuse the old pulley mounting plate as a base.
I needed to get measurements for the bracket, and for that I needed the rest of the parts. I held the bracket and motor in place where I thought it should go and measured the distance from the spindle to the motor shaft. I then measured that distance out across an old 2X2 and put screws in place. That allowed me to take the top pulley off the spindle, place it on the 2X2 along with a replacement 4 step pulley and get an accurate measurement for a fan belt.
It looked a little odd showing up at a parts store with a 2X2, but it worked a charm. They found a pulley, measured out a belt, no problem.
Making a Bracket
With the replacement step pulley mounted on the motor I could measure the distance from the top of the pulley to the top of the existing bracket. I cut a piece of scrap at that measurement, tied it to a yardstick, and that allowed me to figure out how high the bracket needed to be mounted. See the photo, that explains it better. I drilled holes in the existing bracket to match the bolts in the mounting plate.
There is almost no room between the motor casing and the bracket, so I had to shim out the bracket from the mounting plate. The picture shows that the motor is up against the nuts as it is. However it does work, it all fit together. Once gain not perfect but functional.
