(This is an archive of updates from 2020. For current updates, an explanation of what this all is, and the reason that a quotation and painting from 1920 appear above, go one level up.)
Sawhorses
2020-05-18. (Something potentially useful for a change.) Re-creating my favorite sawhorses. With a CAD model and drawings.
G0759 Mill Enclosure
2020-04-18. An experimental/prototype enclosure for a Grizzly G0759 manual milling machine (without flood coolant).
Angle Blocks (after Pieczynski)
2020-04-03. For making a part for my Barth Type Caster I needed to machine a setup tool (an angle block) with an uncommon angle (8° 20′). To do this I used a very elegant method that I learned from a video by online machinist Joe Pieczynski.
Junior Engineering (1976)
This isn't an update about a current project. Instead, it is an entirely personal recollection of two extraordinary shop classes that I had in Junior High School. If they weren't unique they were close too it. Google knows nothing of them. They deserve not only to be remembered but to be revived.
A Matrix Electroforming Case
2020-03-06. The most remarkable, and probably the most difficult, method of electroforming typographical matrices was that used by the late Andy Dunker. It's no fun starting with the easy way.
