Well, home it came with me. The seller was very friendly, he had come by the machine some time ago from an estate and ended up having little use for it, but appreciated it as a neat little grinder. Moving it was a little tricky as I wasn't driving my pickup today, thankfully the cabinet base for it put it at the right height for the two of us to slide it into the back of my Xterra. It's a pretty weighty machine in spite of its small size, the Grenby catalog posted earlier lists it at 320 lbs.
Unloading it solo was a little tricky, but I got it done with the engine hoist and set it down on the cabinet, which is pretty robust despite being handmade out of wood.
The cabinet base was definitely designed for coolant in mind, the grinder is mounted to a wooden base, with a well made formed galvanized coolant tray with a channel around the perimeter, as well as a drain hole with a brazed in copper straw that has since broken off. Unfortunately the corners have cracked where they were welded and the tray has suffered some damage. Also whatever reservoir and pump system was underneath, if there ever was one is now missing.
A couple oddities about this machine; someone has replaced the original motor with one that is incorrect. The original spec was a 3450 RPM motor, that has been replaced with a 1725. Additionally the seller told me me that it spins the wrong way. I'll have to source a replacement.
The other odd thing is that someone has installed a homemade t-slot table onto the machine. If it were meant to be this way, it would have been cast as such and finish machined by Grenby.
Based on all these DIY accessories, I'm thinking the original owner was someone who was too cheap to buy the Grenby made base for the machine and their mag chuck to suit it and devised all this instead.
Here are some more general photos of the machine as well as it in my shop with its brethren:
On the positive side of things. Everything moves freely and seems operable, although maybe in need of a clean and lube on the sliding surfaces. Down the line I think I would prefer a base made of steel tube as well, but currently I don't own a welder.
