Haven't had much of a chance to do anything with this project lately due to the kids and wife sharing their germs with me.
However, this evening I DID manage to do the turret board ready to mount all the components. Its not as straight as I had hoped, as it turns out permanent marker pen doesn't actually stick to PTFE board.
Hopefully the plan for tomorrow/this week will be to mount the components to the board and start fixing the hardware to the chassis. I've decided to just leave the chassis as is, instead of trying to paint it.
