What make is this surface grinder

[f350ca]

It made its way to its final resting spot. Ran power to it and fired it up. Im half deft but all I can hear is belt whine, think the bearings might be alright. After about half an hour the spindle is slightly warm so the belleville washers must be achieving their preload.
May need to invest in a better indicator now that we have something that should consistently work to 1/10ths. With a 0.001 indicator the table shows no movement down the axis and maybe 0.0002 high in the middle across it but the indicator is bouncing over the T-slot so that ones a bit iffy. The magnet face is true across and about 0.0007 high at the right end. Will remove and clean again and see what we get. So Im happy with that.

 I don't know enough to be even dangerous when grinding so we dressed this orange coloured wheel and gave a piece of mild steel a go.
The washers are covering the specs, does that even look like a candidate for mild steel?
The result,


In better light




There is a sort of pattern there or is that the saw marks telegraphing through, only took a few thou off. A 1 though cut would blue the finish, this was about 1/2. How fast do you feed the table? This was at a pretty good clip, didn't want to blue the metal. May need to come up with a spray coolant.
