( Krypton Interrupter combined heatsink - end screw holes
( for mounting fibreglass mounts
( Drill 8mm deep nominally - sothat break-through to M3 avoided
( Set start reference datum at x+500, y+750
( x formica offset = 51.20 mm so x = 5620 
( formica thickness 10 mm so y = 1750
( Install #36 (2.65mm) drill for later Roll Form Tapping M3
( Spindle speed set to 2500~3000rpm
( operation begins automatically when quil TDC switch is opened
( raise the quill at the end of the last stroke
( with appropriate care the part can be removed during the parked condition
( 80% Kero+ 20% RTD used as cutting lubricant
( .
( datum is x = 5 mm, y = 5.5 mm, but extra 2 mm to edge of extrusion
