Things are pretty quiet around here, so I thought I would show something that I have been playing with recently. Using my bolt-on CNC for the lathe I wrote a little script with a few parameters that spits out gcode that lets me cut internal or external threads for boxes, etc. Suffice it to say 0.7 mm pitch isn't going to be useful (but can be done!) and the 2 mm pitch either needs multiple passes or CA glue to prevent some of the chip out. The router with the collet adapter also has way more runout than I would like.
