So there's metal and Carbohydrate Foam in this.
I built the future Step kids Some "Banks" for Christmas this year.
The little Pirate Chest is just some Tong and groove pine board. The Bands are 16ga (.060") mild steels (cnc plasma cut)
The Stagecoach box is a 10Ga (.120") mild steel Frame (CNC Plasma cut) and 16ga (.060") mild steel Inter box.
The Steel was treated with Caswell Black Oxide. then covered with Flood Pentrol. Rubbed on and wiped off.
The Striped Box is 1/4 sawn white oak with a Purple heart /Paduka Stripe.
All the boxes were felt lined (mostly to protect little hands from my crap welds! and to look nice.
Now That those projects are done I can try and focus on the pile of patterns that are building up around my 3d Printer.
