Totally awesome! I made a 4-plate rack out of 4" electrical covers, but this is way better! I never saw the plates you're using, do you still have the SKU#?
hahaha!, I am using the exact same plate as you!, I only cut them smaller with a 2'' round paper pattern, cut by hand with scisor wiss and finish them on the grinder, that's why they are not perfectly round, this hurt the hand to cut that!!!
