Whenever I had to do work on or under the layout, I found there was no place to set my Dremel tool (I usually use the flexible hose attachment)., or no place to hang a trouble light under the layout. Some years ago I decided that every time this happened, I would install a cup hook to hang the required tool. I now have over a dozen hooks scattered around the layout, mostly under, but a few on the lighting valence. All, of course, out of regular sight, and none where they can snag clothing, puncture skulls, etc. Now, whenever I have to fix something under the layout. Yes it still happens!! :curse: Thanks for asking!! , there is a hook in exactly the right place.
