>I can tell you how I form the sides
Firstly I mill the soles,the dovetails and the mouth opening (undersize), then transfer the dovetails into the brass plate sides that have been pop riveted together, then mill the side dovetails.
I have a template of the sides that I photocopy and glue onto the sides ,aligning the dovetails, I use this as a guide to bandsaw the sides and drill the holes for the retaining rivets . I will now finish the contour(while still pop riveted) with various shaped files.
With the shaping finished I use Hermaphrodite(odd leg) calipers to scribe a line where the chamfers need to be, then using files again, file to the line.(But you will have to retouch these up after the sides have been lapped) The pop rivets are removed and the two inside side are now polished before assembly.

Hpoe this helps
