I set up my alodining area in the large shed at the back of our property. Chromate is really nasty / toxic stuff and needs to be treated as such so this will be done away from the build area. I use normal plastic 45L storage bins for the majority of the parts and made up longer baths out of 100mm x 65mm storm water down pipe with the tops cut out for the loger parts, spars and so on. The larger bins on the floor are for water rinsing.
