Just catching up with this as have been soldiering on, neglecting the log and photos.

On Sunday started off but rebuilding the knackered chipboard with two part wood filler. Build up, cure, sand, repeat four or five times.
This was after first layer...didn't take photos of the gradual improvement...doh...

Next fit the new laminated board front. Did this as close to original method as I could.
Pic one, offering up...

Pic two, as good as I could get...

Pic three. Joints inside.

Pic four. Low tack tape where I will be marking up the cut lines.

Pic five, start button, coun door and shooter rod added....

Pic five, what lies beneath....the left hand leg is level, but the bracket is a bit skew.

Finally, back in the line up getting a good play after fitting another new coil and attaching elements I had removed to clean and polish....oh and some new side rails...
Next, lamp driver fixes and chase down some switch capacitors that aren't quite right.
