This are two of my favorite new Fireball tools in the shop. The Magic square and the magnetic shim blocks. The Magic square is a adjustable fixture with tons of options for any situation. The Magnetic shims are like 123 blocks. They come in all different sizes. They have magnets so you can stack them together to make different size stacks.
