Hi fellas, sorry for the long wait, life has been extremely hectic with school and work. I have managed to make some progress on the bike frame. I got some help to correct the miters on the tubes with a hand file, and the tubes now fit correctly in the jig. The chainstays have also been increased in diameter from 1/2 inch diameter to 5/8 inch diameter. This change was made because the chainstays bear more cantilever loads that the seatstays, and increasing the diameter will help ensure more power from the pedals goes into rotating the back wheel rather than bending the frame. The brake bridge for the seat stays has also been mitered with an end mill. I have also been working on improving my TIG welding skills, which are currently one of the largest remaining obstacles towards a finished product.
