Bridgeport Manual to CNC conversion...

Sub-table for the engraving spindle...



Holes A are for M10 or M12 CSK socket-head screws to bolt into the Bridgeport T-Slots, holes B are two locating dowels on the rear face to sit in the middle slot on the main table, keep it all square etc :)

25mm eco-cast tooling plate.

Dave, once setup drop a couple of shallow keyways in the plate both vertically and horizontally so you can drop a piece of key steel in to act as back and / or side stops to get parts square

Sub-table is coming along nicely, can just be seen in the bottom of the picture, just the matrix holes to drill & tap now...



The new spindle motor fitted my adaptor perfectly, got the VFD dialled in nicely, just the water cooling to sort out.

Job done, turned out very nice.

100 holes, spotted, drilled, countersunk, blind-tapped M6



Surface was parallel to within 0.03mm max so i'm not going to bother running a facing cut.
