It's god awful but you get the idea...so I can re-draw into eagle PCB. I'll do the TEC cooler as an exercise. Also been looking at Cam85m in the Russian forum. mighty impressive. Also saw some discussion on sealing cases with HTS2000. I've used similar Aluminium brazing. It works ok. It's not TIG but it's easy to use especially if you use a stainless brush or wire scraper to clean the surfaces when the metal joint in molten (clears oxidisation as aluminium alloys form oxide layers almost immediately).
