Here’s some pictures of the front triangle fabrication. Seat tube was probably the trickiest part. I machined a fixture to keep the BB and suspension pivots aligned and then used some 123 blocks and a template to fixture the upper portion semi accurately. The lower tube was basically swiss cheese by the time I was done. In addition to the visible cutouts, there’s a large one that aligns with the seat post for additional dropper clearance. I did the fusion pass on everything then located that in the frame jig. I left some stock on the pivots so I could come back and bore/face them after finish welding the frame. Kind of a nerve-wracking operation but I snuck up on the dimensions and luckily averted catastrophe.
