First mockup minus the front 'wing' fenders.
These are easy to remove, the hard part is making their presense disappear.
I've marked the rear fenders for my cuts. I decided they needed to be about 4mm wider to fit the fat slicks. I split some 10mm tamiya masking tape and used the tape to guide my razor saw cuts.
I cut a strip of 0.50 in sheet 4mm wide and rolled it around a bottle to get a rough shape of the fender, then I glued that with some fast setting CA to the inner part of the cut, starting in the middle and working to the ends one at a time. I then glued the outer fender on with regular plastic cement.
Here's the glued up fender extension before any sanding or trimming.
Although it looks rough in that shot it cleaned up nicely.
I'm not sure what's next...
Though I'm trying to get all of the body work at least roughed in.
