Subject: RE: [Homebrew_PCBs] Spring loaded Engraving bit holders

Mark,

If the spacer is threaded it could just be given a slight turn to adjust the depth.  There could be either thread friction or a clamping collar to keep it from rotating.

  I’ve been wondering how to make a spring loaded spindle with depth adjustment that can fit in that Morse tapered tool holder of my CNC machine since it doesn’t have a spring loaded motor/spindle. 

Making a spring loaded engraving bit holder is easy.  Making the depth spacer that’s easily adjusted is the problem!

 Cheers,

Mark
