Progress was halted a bit today, as I was forced to do emergency repairs to the fine grillwork on the sides of the tower.
Originally I had thinned the plastic from behind, and then drilled the individual holes.
Well, with all the sanding I've been doing lately, it really weakened those areas until finally it started breaking apart between the holes.
There was nothing I could do to save it.
Luckily, I still had leftovers from the U-Brass set that I could graft into the tower!!! Kudos to Wink & Dougie for creating that set, you saved my bacon AGAIN!
I carefully cut out the PE pieces, and filed the edges close to the holes. Then VERY carefully I cut matching holes in the plastic tower, fitted the PE pieces, and used CA to glue them in place flush. To seal & blend the edges with the plastic, I applied a bit of CA around the outside edges, then a squirt of CA Accelerator hardened the CA. Some light sanding later and voila! Nicely grafted pieces. A quick brush of paint showed no edges... looks good!
