How do a drill a hole?

(1/2) > >>

John Hill:
I want to drill a hole accurately in the end of a shaft so that I can clamp a tool in the manner of a collet.

This is a simple job to fit a centre drill to a Morse taper blank but every attempt so far has come out crooked. :doh:

Here is a sketch, of course the male bit has a saw cut so that it can compress somewhat as it is screwed into the shaft.



I drilled the hole with the two bits screwed together and mounted in the lathe spindle taper.

Did you cut the slot before you drilled the hole?

John Hill:
No, drilled then cut.

No1_sonuk:
How many cuts?

Could it be that the hole is accurately concentric, but that the grip isn't.

John Hill:
I have only one cut in the 'collet'.
