Yup, racks are easier
Built 2 racks this week, repaired a broken one, made a replacement piece for a different one, and started another. In ~20 hours all told (including a few runs to the hardware store for oxygen; next week I have to get off my butt and go out to Airgas and see about getting a new bottle of oxygen instead of churning through disposable bottles as if they were candy) which is about the amount of time it takes me to sew one handlebar bag.
