Great stuff! Thank you very much! It would be helpful to know a couple identities/sources: What kind of pump did you use? Is is a kind that can handle metal chips in the fluid stream? You didn’t mention using a filter, and there appears to be some chips and some good size chunks of metal in the “runoff gutter” of your collecting tank.
What kind of cooling fluid, and a suggestion for source of hobby-quantity purchases?
I found both US and Asian sources of the articulated segmented “hose” and nozzle pieces on eBay.
