I was very careful around the bearing saddles in the case while I was grinding. I didn't cover them with old bearings, but that is a very good idea. I was just very cautious around them. I would grind away, then I would very gently clean the saddle surfaces with an old tooth brush being careful that I was not pushing the chips into
the surface of the saddles as I cleaned them. I very gently would push them off to the sides without pushing down on them.
Here's a pic of the rig I was using while grinding:
Not the prettiest setup, but effective. I had a box right under the case half on the engine stand to catch bigger chips that fell, and then I had a shop vacuum hose right in the area I was grinding. The vacuum sucked up the vast majority of chips.
I'd mock up the crank, see where the case needed clearancing next, grind away, clean, mock the crank, etc. It was very redundant. But with a lot of patience and frequent sanity break it took me two mornings over a weekend.
