Today was a bit disasterous. I'm using Glazelite acrylic sheet on my pull-out trackball panel. I cut the piece to size, and then started to practice using the holesaw on a big offcut. I cut a couple of practice holes no problem, but then reallised that it wasn't the offcut I was practicing on, it was the actual piece and I just ruined it!

Rather than buy more acrylic I decided to use the offcut piece which is actually smaller than the top of the trackball panel. This shouldn't be a problem though because I will just have the panel not pull out as far.
I think I've just about finished all the woodwork now. Must get round to doing that artwork.
