The Week

My garage right now: three utility trailers, a bike chariot, a coffin cargo bike and 15 bikes depending on the day.

Boring out the bronze bushing to fit over the center post.

---

The bronze bushing sleeved over the center post.

---

Machined end cap that the tapered roller bearing sits on.

---

Welded onto the top of the center post.

---

Very jankily truing up the ends of the spreader tubes. The lathe is maxed out at 37.5" and I had to use a boring bar to reach the end of the workpiece.

---

The lower hub assembly tack-welded to the spreader tubes. I had to be really careful to make sure the heat of welding didn't distort anything and cause a bearing to bind.

---

The upper hub assembly, upside down on my welding table, being tacked onto the spreader tubes. The main bearing sits inside that square piece of plate that's just under the end of the center post.

---

Finished lower hub assembly with arms attached.
