#73bunch of weirdness, but my hobby is building sprayed in facecoat glass fiber reinforced concrete pieces.

#78About a year ago, I spent a weekend building a letterpress. It's turned into a fun hobby. Printmaking is much more difficult than I'd have expected. One of the biggest challenges is maintaining a clean, inkless field. It's so easy to get ink on your hands, at which point it's nearly impossible to pick up a sheet of paper without smudging it before you're within three feet of the press itself.
