I've started work on a motorized indexer for my rotary table. At this point I am not calling this a fourth axis. The way this will be used is to (1) rotate the table, (2) clamp it down, (3) perform the drill or mill operation (4) unlock) then if not finished go to #1. A fourth axis would

Industrial recyclers also discount aluminum swarf unless it is in compacted puck form. Much of the uncompacted swarf oxidizes (disappears) when melted. The pucks melt the same as solids. On Sep 25, 2016 12:50 PM, "Todd Zuercher" wrote: A number of recycles don't want

I believe that Jon Elson suggested the QSE159. Digikey has it in stock for about $1.50. It includes a Schmidt trigger for noise immunity and the datasheet doesn't mention anything about bandpass filtering. > -Original Message- > From: Sarah Armstrong [mailto:sarahj.armstron...@gmail.com]
