I started building Rob’s steel road frame (below) and something seemed sort of weird. Didn’t I cut the downtube on the last frame exactly the same length and angle? Wasn’t the jig setting for the last frame exactly the same as this? Oh no, am I building off of the wrong blueprint?…nope, the name is correct. I better go grab the file from the last frame. What do you know, the last two frames in a row I built are nearly identical. With the exception of 4mm in headtube length both frames are the same. That’s a first.
