Sorry for the lack of posts, things have been busy, but the frame building should pick up at the beginning of May. I had to take a couple of hours to machine a new heat sink/argon purger, so that I could weld up Matt's front triangle. This 27.2 sink goes in the seat tube and the fitting is for pumping argon into the tubes for purging.
Matt's frame has been slow going, but is turning out rather nice. Tomorrow I should be able to bend up some stays for the rear.
