As part of the 2007 SIC XXI conference at Harvard University and MIT in Boston I conducted an instrument-making workshop. The purpose of the workshop was to introduce some aspects of metal working to members of the scientific instrument community represented in the SIC. The participants found the workshop, designed and lead by Richard Paselk with the aid of Richard Kremer, to be a resounding success.

Provided tool-kits & materials for each participant (in metallic "wine-bottle" gift bag): A four oz ball-pein hammer, a two-inch C-clamp, a scriber, a set of steel figure punches (1/8"), a six-inch wing-dividers, an aluminum bench block (2"x2"x1/2"), a six inch stainless steel ruler/straight edge, a set of five needle files of various cross-section, a center punch, safety glasses, a 12 inch strip of one-inch course sanding cloth, a 4"-5" 16 g pre-cut brass quarter-circle, plumb weights with string, two sights, screws for sights, and small brass squares to practice tool use.
Group tools: four “eggbeater” drills, ten each 1/16” and 1/8” drills, four sets of letter stamps for adding names etc. (two each 1/8” and 1/16”), two pin-vices for holding drills for cleaning hole, misc. long-nose pliers and cutters for working with line.
The workshop: For this venue each participant constructed a working brass simple (nautical style) quadrant of brass using provided tool-kits and materials. After some brief instructions the 20 participants began by punching a mark for the vertex of the instrument and then laying out the arc with a dividers and then using “original division” to lay out the scale to 15°. After trisecting the 15° segments by approximation with the dividers the room erupted into a cacophony of banging and pounding as the members used hammers and figure punches to mark the major divisions at five degree intervals.
