The aluminum looks like a very nice solution. You may be able to make it longer, wire it up, attach wires, drop into place and attach and wire near the top.
I haven't been on the site for a few years.... boat resto on hold due to a bad hip and incompetent doctors! It's nice to relax and read some threads!
As for getting down to the bottom of the bilge... last summer I put my wife down into our well to clean it out as I stood up in the sun on crutches looking down laughing..... my point is you need a wife like mine to put her head first into the bowels by her legs because she will fit ! Or find a small child.
As for the coffee table.. we just got a new one so I immediately sent the video to her and all my kids via text!
But seriously.. I do like the angled stainless that Lt. Mike created. I may go that route. I just Sunday pulled both bilge pumps and the little wood blocks that were under the formed fiberglass. So much to do... not enough days in the week!
