Awesome, look forward to seeing your handywork, no judgments here, any inspiration would be helpful! I was in the LHBS shop on the weekend and the mill setup they were using made me feel very good about this purchase!
I'm considering one of these if a 20L Maxipail from Bunnings fits underneath with the middle shelf removed.
