anybody  made 'his own' CNC drill/router?



See mine here:  Photos;  Jan Rowland (near end of  all).  The PET you see on 
the left once controlled it.  The last PET  finally died several years back, 
and I am now converting the drill-control  circuitry to be controlled off the 
LPT-1 of an ancient PC running  MSDOS/GWBASIC.  Does about 50 holes per minute.
 
This was a very educational project, built in 1984.  Based upon some  of the 
details I taught myself doing that "PCB Drill," I subsequently built some  
serious PC-controlled X-Y router gear for pipeorganbuilding shops, even one in  
the UK.  Too much work for lazy people, so I retired while still  living!
