Crossflow build for my Bok

[Expat]

After much reading and thinking I got around to building the crossflow condenser. Definitely the most complex build i've undertaken to date, so I thought I would share the results and some of the details.

Previously I was using a double wound coil, which was functional but essentially used up every inch of head room available in my work space. My intent is to maximize the amount of height available for packing; also its hard to resist a fun build project

So here is the completed build:

The shell of the condenser is 2", and the total width is 18"; internal setup is 21 flow tubes of 1/4" that are 16" long. To be clear, its designed to be overkill I'd rather have more than I need.

Reading through the forums, one of the biggest build issues noted was the blind weld of the end caps over the tube plate; with this in mind I thought it would make sense to go with a removable cap joined by an EasyFlange. As a side benefit this means that the water path is open an inspection/repair if required.
