The West Coast Chapter Toured their shop a few years ago. I've been back for two Model T radiators. A fan blade broke and ruined the first one they made. The return inlet on the second had to be modified as the cross member it sits on was bent. They reworked it and didn't charge me anything. I have been very satisfied with their work.
Building a radiator is an incredibly labor intensive process. My Star radiator is made up of hundreds of square tubes that need to be stacked together and then soldered. When I replaced mine, I had it done in England. The cost was well north of $3,300.
According to BW, it takes a year of training before someone can be expected to do a radiator on their own. The California labor market is very tight and our environmental regulations are the strictest in the nation.
