I've seen a couple of vids on youtube and I saw the setups were basically a box fan motor with a shrould made around it like the box fan already has but a bit taller to keep te dye from splashing elsewhere. They then placed a round piece of wood with some foam on it to place the disc. I just haven't gotten around to finding the mixing ratios.
always looking for:
flat pink/red barstamp buzzzs, ce aviars, pearly pro candy fb's, pearly champion gators (fr or stock stamp),
