The lack of access to a cost effective machining solution has prompted the construction of Acrylic parts for the frame of the galvanometers. Hopefully these pieces will be replaced by aluminum ones, but for now I’ll at least have something to work with that is more substantial than wood. Everything is cut but is still in need of drilling and tapping. I still haven’t been able to find an appropriate tap handle for the M2 size tap or 2mm size set-screw collars (well, in quantities less than 100). I’ll need to find sources for both of these items before much more work will be completed.

After three months of waiting, I finally received Ungar part # 9037, a Tip Retainer for my (somewhat) vintage 9911AS soldering iron. It doesn’t fit. Action-Electronics is going to get a call tomorrow, then I’m probably going to start honing my metalworking skills to modify this part… or something…

I still hope for a positive end to the week with the arrival of a HeNe Laser Power Supply for that old 6.5mw tube I’ve got in the basement…
