The exchanger is now mostly complete. All that remains is to pick up a 5/8" drill bit, some heater hose. Then I'll need to drill the caps for the oulet pipes, solder on the end caps and to fabricate some clamps to mount the exchanger with under the hood.
I managed a total of 5 lenghtwise runs through the exchanger with the 1/2" pipe. This was the exact maximum I could fit.

Here's the end view. You can see how tight the fit was, I had to mash on it just a bit with the vise to make it fit in the pipe since some of the lead bonded the pipes toghther just a bit. Next I'll just need to finish up the caps.

Here's the Heat exchanger completed and installed. The water lines are 1/2" flex hose from the hardware store. The Heater is 5/8" heater hose from the auto store. I removed the line from the front of the engine, where hot coolant exits the thermostat housing. I attached that end to the heat exchanger and added a new line from the exchanger to the thermostat housing. This way the hottest coolant goes into the exchanger first. It shouldn't adversely affect the heater in the winter, but should heat the water nicely.
I field tested the system using lake water down in Arkansas to SCUBA dive. It made the 69 degree lake water into a nice warm shower. Not quite hot, but a good comfortable temperature. The water pump performed very well, since it sucked the water up from a 4-5 feet below the jeep, up to next to the battery, and out the shower line.
