I use dollar store superglue rather than hobby superglue due to price and size convenience.
I can get 3 small tubes for a dollar versus $12 for a small bottle of hobby cyano-acrylates.
The hobby glue also has a habit of drying out before I can use all of it which is even more of a waste.
I also use standard styrene glue for larger flat pieces. that aren’t going to get a lot of handling.
Paint adds extra strength for those pieces and acts almost like a second type of glue.
You’ll probably spend over $100 in supplies to include styrene sheets in different thicknesses and rods and block strips.
The multi-sheet packs are around $12, with the rods and strips about $5 per pack.
Tool-wise, you’ll need at least 3 X-acto razors, a pin-vise and multiple drill bits and different blades.
Then there are saws, metal rulers, hole punches of different sizes, micro files, sprue snips and storage containers.
The tools are where you will spend most of your money as the pin-vise alone is more than $20.
You will also need different grit sandpaper as well as many emory boards.
All this isn’t to dissuade you, just an FYI in what kind of commitment you will need in supplies. It is worthwhile for the long run but
A waste for only a few pieces. Considering your investment in painting supplies, it might be worth it for you and may even provide
many more hours enjoying our playing pieces. Beware, it’s a slippery road to obsession. I’ve found that I’m even modifying pieces
I have already put a basecoat on as I learn new techniques and modifications which might not even be noticed on the playing board.
