Weekend Steam: Lapping A Steam Engine Slide Valve

 Here is something you won't see every day, and you even get to see the grit selection used for the process. Many Thanks to Merle for spotting this one!

That saves a bunch of human powered labor.

When we lapped valves in the shipyard we used a figure motion if possible, and the grit size is not longer in my memory bank.
