My current drill press (craftsman 12" bench model) is really taking a beating, I seem to be getting into a lot of bigger projects lately that it just is too small for. So I began to shop for a bigger one, I wanted a floor machine, and was looking at the bigger models at HF. I'm glad I waited, because a monster of a machine came into the scrap pile at work. I pulled it out, but was immediately discouraged at seeing the setup of the machine. It's an IMA IG-30-8, geared head. Problem is, it's an integral motor, and 575 volt 3-phase, which I have no way to run in my small home shop. I was going to put it back in the scrap pile, then had an idea. This is how I got around the problem.
Here is the "donor" motor. It's a 3/4 hp 220 volt 3-phase. Just one I had laying around.
Here is the motor disassembled
This is the main body of the drill head. The large middle cavity is what houses the motor.
A shot of the motor cavity
Here I've pressed the donor motors core off the original shaft, and pressed it onto the turned-down shaft from the drill motor
This is thick wall aluminum tube I ordered from speedymetals. It was the only place I could find this piece
Turning down and boring the sleeve to a press fit for the motor cavity and new armature.
So far so good
Here is the gear head reassembled.
Waiting for my vfd to arrive, I tackled the table. It was full of drill holes from its previous life, so I welded those in and set to resurfacing the top. My makeshift surface grinder did the job well, but that will be the last time I do grinding on my shaper. The grit goes everywhere, including the ways.
Here it is mounted on the column. Notice the base, I had to fabricate a new one, as the original had been shattered at some point getting tossed about by heavy machinery in the junk pile
Vfd arrived. Got it from eBay, not a bad price. This model is good for 2hp, just because it wasn't much more than the 3/4 ones
Here is the latest pic of it. I had test fired it, and it runs great! Still have some things to do, machine some handles for the gear selectors, I just finished the quill handles today. FYI, the vfd's are set at 400 hz from the factory. It sounded like a jet engine until I adjusted it!
---------------------------------Why buy something when you can build it for twice the price!
