Our daredevil kittens have made horizontal set ups challenging, and they have a history of chewing on cables.
My solution to this was to redo the piano desk vertically and with an accompanying cat tower that gives them an alternate safe path for climbing on top.
This project also tested the ability of my 60W 20x28 laser to cut through 1/2” plywood in oversized pieces. This sort of worked - I was able to use an index pin method for feeding the stock through the machine with sub-millimeter alignment, and I was able to cut 1/2” using multiple passes with a 4” focus lens (10mms, 60% power, 5 passes). However, the ply edges were charred, which created a loose and somewhat irregular kerf. I also had a problem on one sheet that through off my alignment, which I was able to somewhat correct but this resulted in some missing fingers on the back of the case.
If I were to do this again I would try ply with a soy based glue like Columbia Purebond. I’ve seen some examples where lasers like mine can cut 1/2” melamine glue plywood in 1 pass, but I don’t seem to have a local source for that type of plywood.
The case is finished with GF gel stain and wipe on poly. I had these left over from other projects, and since this case has a reasonably high chance of being scratched up, I decided not to sweat too much about the finish.
The cat tower I did in Fusion 360 but used a circular saw to make all the cuts, except for some internal corners where I used an oscillating tool. It’s painted to make it easier to clean and then covered with a carpet remnant. A hole in the top of the tower allows the cats to get on top of the piano lid at the same level. The lid is held up by four 2x4 painted with left over paint.
