Easy, just keep it level, then if you drop a tool it should just hit the metal tube on the opposite side of the finder and not glass. Little dents in the tube are cosmetic, they don't affect the performance of the scope. To foolproof it take the tube off the mount and put it on a chair or table, perhaps on a folded towel or blanket to stop it rolling. Perhaps looking out a window so you can see something in the distance to help you get it aligned right. Or outside, where ever you've got enough distance. Do it during the day, that should also make it easier to see what you're doing. Point at the top of a tree or lightpole or building as a guide. Then at night time find something really bright and fine tune it. Robert should be your uncle after that.
Anyway, hope you do get together with Ron in the near future. I had the pleasure of sharing an observing night with him in December when he was on this side of the country and he's a top gent.
