favorite surplus hardware store closed down and went to auction, regret not buying more stuff...
That's a 3/4" craftsman wrench for size comparison.
Anyways, got this guy for $10 and they were nice enough to forklift it onto my trailer, nice enough to remove the guards with the forklift too. I got some practice TIG brazing. I was using silicon bronze rod (3/32", should have bought at least 1/8") It is interesting, works good on castings, use the torch to get the whole thing up to somewhere between burning your hands and where it starts to discolor, then start applying heat with the TIG torch being careful not to melt the base metal, on this I was using about 60A of AC and it was flowing out pretty good.
No flux or anything. I have terrible luck torch brazing. One thing to note, there's zinc in the bronze. I felt like death was a perferable alternative to taking deep breaths after a while at it. Just bought another respirator for at home because of this lesson, already had one for at work.
The bearings had a lot of radial and axial play in them, but felt fairly good, so I made up a spacer to preload the 6205s that were already in there. When I finally put power to it they run smooth and quiet, so no reason to replace them with chinese ones.
Made up one tool rest so far, was going to go all out and mill a slot for a sled but decided that I can just use the outside edge as a guide rail for any sort of sled I make up later on.
Gonna make retractable guards to replace the sawed off tops of the castings eventually. Going to run it off a VFD because 1750 RPM on a 10" wheel results in a real low surface speed. Figure I'll run it up in the revs to get the normal 5,000 SFPM you want on abrasives.
Someone was gentlemanly enough to use sandpaper on the dataplate.
Reading between the lines gives me 1HP, 9200 4835 model number?, 1750 RPM, 220v, 3.2A, 3ph, 60Hz, serial number?, 10" wheels?
Best I got. Plenty of googling brings up nothing looking even slightly similar.
