More Bicep Work, Forearm prep and belt raw trim.
After some testing, I decided to up the shim width to 15mm, and the cover strips to 25mm, just for more wiggle room.
To act as a foundation for the shim, I used a 30mm wide strip of ABS in the inside of the bicep, used superglue to glue the shim in the middle and e6000 to get it all together. Magnet and clamps per usual.
Cover strips were then cut to 25mm width from provided ABS sheets (to ensure colour matching, though there was still a little mismatch annoyingly enough). Contact sides were sanded roughly and glued using e6000.
Both biceps are now drying and should be ready for strapping later on. Forearms are next, and before that I used some hot water to straighten out some curled-in surfaces on the inner forearm.
Protip: since I needed to do many straight cuts for shims and strips, I 3d printed out setup blocks with specific thicknesses (15mm, 20mm, 25mm, etc) so I have consistent measurements. Beats having to use a ruler to mark out widths or waste ABS for templates.
One more task that was done was rough-cutting out the ABS belt. Since I wanted to get as close to the boxes as possible I used a combination of a Dremel cutoff wheel and lexan scissors to do rough cuts, and finished the edges using a deburring tool, a hobby knife and sandpaper. Corner angles to be cut once I get to canvas belt attachment.
Next up, forearms and legs. I think I need to look more into how the foream parts line up since the outer forearm is much longer than the inner forearm.
