Well, my pappy useta say D****T boy do sumthin, even if it's wrong.

Following this sage advice I decided to use 16ga copper electrical wire (.050" diameter) for the cooling pipes. A block was made with grooves .070" apart, as I wanted some space between adjacent pipes in the row

The brass strips at each end are only to hold the pipes until the second layer is attached. Here the first layer are soldered to the strips

Then the second layer of pipes is nested between the ones in the first layer, and soldered. This will be the bottom layer when finished

After a good scrub with Comet cleanser and a toothbrush the top layer looks like this.

It will need a little scraping with a graver between the pipes to remove small amounts of excess solder, but so far, so good.
