Earlier today I managed to squeeze some more work in

Cut out, mounted and drilled out the correct idler wheel dish shape. Lots of time spend with a round file to get the inner and outer diameters right. The inside holes I messed up ONLY once trying to drill them before mounting the wheel... I ended up simply drilling between the PnzIII wheel posts on my drill press after gluing the plate & wheel together.
The turret front and first roof plate are glued permanently. The rear and middle plate will be removable for access to the internals.

Next is mounting a gun & making the mantlet!
