April 2005 I start my PCB Mill



This is the X axis and bed done but for mounting the motor
you can see the bed for the Y axis already started in the background
and the aluminum channel for the Z axis



Heres a better shot using the flash



Aluminum channel from the glass shop and pvc plastic make up the bulk of the unit,
and lots of 4-40 screws. Everything is adjustable so that very little precision is required
in cutting and shaping of the parts.



Heres the flanged bearing held in place with two sheet metal screws and the end caps are held in place
with no. 10 sheetmetal screws






The motors came from an old Pitney Bowes fax machine I need one more for the Z axis.




Heres a view of the floating nut that makes any inconsistency in the threaded rod
into smooth motion







Yikes it's been awhile
Heres the copper ready to be etched



These will be etched using a solutuion of hydrochloric acid and
hydrogen peroxide
