The new panel lines are now done, and the unwanted ones filled, the radiator and oil cooler joints have been sealed, and the holes drilled for the cannons, with the empty shell case ejector slots cut into the lower wing.
PIC 1 Shows the scribing for the cannon ammunition hatch, and the centre machine gun access hatch moved outboard. The original hatch has been filled with PVA, not really visible here as it dries clear, and this will be 'backed up' with some home-made 'porridge' later, which will also be used to repair the crack in the filler around the cannon blister hatch.
PIC 2. The holes drilled for the cannon and stub fairing, as well as the new hole for the MG port, moved outboard, and the original gun port filled but not yet sanded.
PIC 3. The MkVb shell ejector port has been filled, as has the engraving for the landing lamp cover, and new ejector ports drilled and filed to shape. The small blisters towards the wing trailing edge have yet to be made and added, and these will be carved from stretched sprue.
There's still some polishing and clean-up to do, then it'll be time to move on to the main construction, most of which will be OOB.
Thanks again for your interest and kind words.
