Equipment

 

A dedicated puzzle piece notching machine.  Using Qbasic the PC controls two stepper motors, 3 air cylinders and two solid state relays. A small stepper does piece positioning, a large stepper controls the cutter height.  Two air cylinders are for piece clamping and one for table movement. The two solid state relays are for the saw and dust collector AC power. Started out as a Delta table saw.  The only original parts left are motor, table and power switch.

Tormach PNC1100 Mill.   Just got this in 2008.  At 1100 lbs. it was tricky getting this baby elephant into the basement.

Here is where I inadvertantly try to drill through a hardened parallel bar that I forgot was under the workpiece - kind of funny.cnc_mill.html
Machining pieces for a pentagonal puzzle out of white Delrin. That’s a custom cutter in the mill. I had a 20 degree tapered end mill re-machined to 18 degrees.cnc_mill.html
