Coolant guards for a B&S 510 Surface grinder.

[Luvtofish]

Im wanting to convert my 510 surface grinder to a coolant system. I picked up a coolant tank and pump but need to construct a containment shroud and return drain. B&S offered an optional coolant system for this unit but finding detailed pictures on how it was built is as rare as hens teeth. besides a frontal pic in the manual, I found one picture (below) of a unit that had a portion of the guards still intact. the manual says the rear guards were made from two overlapping pieces but no further details. Curious if anyone out there has pics or a good understanding of how the rear guards were made? Thanks

The back guard is perhaps about the same height as the RH table guard, the front guard is about the same height as the back, but about 1/2 of the length is hinged and folds to the left to allow loading and observation., at least on the 618 micromaster.

Thanks. I did see some pics of a 618. The geometry of the guard in the rear and left side appears moderately different than how it could work on a 510.

I am in the process of converting my KO Lee 618 to coolant. So far, this is what I have decided:

1. An adjustable (Up/down) shroud directly behind the wheel. Just a flat plate that can be adjusted up or down in the Z axis to coincide with the wheel. This will prevent spray from hitting the column.

2. A square sheet metal U-shape inspired by the typical end cap found on surface grinders. Same height as the original guard, but the U wraps around more than the original and extends into the X axis about 9 inches on each side. This captures the coolant flung off the wheel.

3. I drilled/tapped for a drain hole, but of course the grinder's X table isn't specifically built to drain toward it. I will have to use a paint brush when I'm done to move any standing coolant into the drain.

4. I intend to use a simple coolant such as Kool Mist. It's cheap (about $40 per gallon and makes a total of 32 gallons). I will toss it after a couple of days or whenever I won't be using the grinder for a week or so.

It's a semi-auto with an automatic hydraulic X. I will add a motor to Y for stepover right after the coolant project is done. No intention to motorize the Z.
