This build is awesome! I love what you're doing with it. If I could make any tool/equipment recommendations, my tip would be to avoid cheap tools, especially brushes. Windsor &Newton watercolour sable, are my favourites. Never drop bristles. Had 'em for years. My other tip would be to browse jewellery tool suppliers catalogs. I was a goldsmith for several years and most of my old tools are now used for models. In particular, good quality stainless steel tweezers. Very pointed and stiff. They hold photoetch parts really well. Get two pairs and spark plug wiring is much easier. Side cutters, too. Good ones, like Larsson (0.35 - 1.25mm copper wire) . They cut really cleanly. Much better than hobby shop sprue cutters. And my favourite of all... Swann-Morton surgical scalpel with #11 blade. I hope this helps
