I purchased this belt grinder from a fellow owwm'er, 40ford. The sander was in pretty respectable shape when I got it ( thanks to fellow owwm'ers peter1 and wm. richardson ), having had its table bracket broken at some point in its life;luckily, 40ford had it professionally rewelded.All the tags and decals are gone ( luckily, a great deal of information is cast or stamped on these machines), so I can't get a good idea of when it was built, but the grinder looks a lot like other "war finish" Porter Cable machines, so it's likely this ol' boy served his country in WW2.
I stripped and repainted the machine Ford gray and installed a vfd, which I agonized about doing incorrectly and came to realize is about as easy to do as falling off a log.I gutted an old Cutler-Hammer fuse box to make the vfd enclosure; from the outside, the machine appears to be powered by three phase ( if you don't look very closely).
The G-4 now holds court in my grinding room, making things flat and grinding things sharp.
What an awesome machine.
