Well, the requirements are pretty basic.
A bandsaw or scroll saw - I'm not sure that any other saw would work.
A drill press
A 5/16" drill bit (I used a brad point bit, it helps with alignment of the bit)
An X-acto knife
Scrap paper (or tracing paper, if you have it)
Thin double sided tape (optional)
Plastic Animal Figurines (I used genuine Schleich
figurines from my local hardware store)
8mm diameter neodymium magnets (I bought a 100-pack, Sku 13518 from DealExtreme
Two-part epoxy or superglue
