Colchester CHIPMASTER -- making a TAPER ATTACHMENT for.

Here's a bit of background for the 1st 3 pics.
To start I used 1 x 3" CRS
squared up the ends to 4 inches and
milled the top to 15 degrees to mate with the underside of the
saddle and help to hold the part in good alignment when drilling
and tapping holes into the pad on the bed.

The parts were then put into the 4 jaw and leaned the same 15 degrees
and bored to accept 1.5" CRS-length was determined by full swivel of
the slide bar and enough room for cross slide movement/staging.

Next the blocks were drilled 5/16" and then mounted on the bed of the
Chipmaster, under the carriage with a 1/8" parallel as a spacer, to help keep both sides
even and clearance. The blocks fit under the carriage like a glove.
They were held in place with a large C clamp while drilling.
After all holes drilled the block holes were opened to 25/64"
and remounted on the lathe. The bed was now tapped with the blocks in
place as a guide, for 3/8 x 16 bolts.Image may be NSFW.
