Day 30 - Shoulder top ring spacers

(Originally posted on September 10th)

I knew these un-level sections would bite me in the butt.  I can't get the markings right for the next layer of bands for the shoulders.  I've been trying to think out of the box about this, but I'm not coming up with anything.  I belt sanded down some of the unevenness, but that's going to make the plywood too thin if I continue.

Today I figured I would correct for the unevenness of the top shoulder ring by placing a level piece of HDF on top of it and seeing where the gaps were.  Then, I measured and glued the spacers to where they touched the HDF (see the pic to make sense of what I'm talking about).


The spacers themselves are 8mm thick, and the HDF is 4mm, for a total thickness of 1.2cm, which is the exact thickness of the top shoulder ring.  I just cut some strips from a 1.2" plywood board, then measured each spacer to the lines I drew on the shoulders.

It didn't take too long to measure, cut and glue them them all to the shoulders.  I squeezed a glob of Liquid Nails onto a spare scrap of HDF and wiped the spacers into the goop to attach them.

Next task is to make some temp cardboard gunboxes to get their relative final position measured and marked for the lower spacer ring.
