Crunch time!
If all goes well, we might actually be riding a working bike by the end of this week. But first, a few critical steps need to fall into place.
Step one: the dummy frame is on its way. And trust me, that’s a big deal. Without those parts, I can’t take measurements, and without measurements, there are no finished lug designs. The bottom bracket and seat lug are basically done, but the head lug is trickier. From the photos, the headset looks semi-integrated, and that’s a minefield: there are so many variants out there that I need exact measurements before I risk ordering the wrong one.
The plan once the bike arrives? Strip it down right away, measure everything precisely, and feed that data straight into the main design.
Meanwhile, a brand-new jig is waiting to shape the tube diameters — and I’ll be testing it immediately. Small mistake though: I made the jig a bit smaller, which means there’s too much tolerance now. Luckily, I can tighten things up by adjusting the hole sizes and range.

Next up is the big jig: the frame assembly rig. The frame needs to stay clamped down for at least 24 hours so the resin can cure properly.
