REALLY enjoying his summer vacation

Luke was first to wear my special sodium-flare notch-filter brazing lenses. After Ling gets back from her Wolves’ Lunch today, I’ll bike to the shop, build my fork, and try out these brazing goggles. They are meant to notch-filter the sodium-wavelength flare of melting/burning flux, so that I can see the underlying metal’s temperature better.
