Sorry for the lack of updates, I've been working on this but I haven't taken too many new pics, I've just been working through. Here are the few pics I have taken.
I made the master for the top rear ribs with styrene strips. Two sizes for the ribs and the spaces between, glued together. The aluminum bar is a guide to keep them straight.
The finished ribs on the phaser.
The last thing to do before painting was to make the rear fins. I cut rectangular blanks on my band saw. Then taped them together and shaped the rear corners.
I then cut each one to length and cut out the inner portion.
And cut the clear spacers from acrylic sheet.
Test fit after gluing everything together. The slot in the P2 was cut too large. Also the bottom fin is too long.
I trimmed the bottom fin and filled in the slot with styrene strips.
After final clean up I gave the P2 halves a coat of Tamiya primer.
