Drilling carbon fibre

[This posting has been removed]

The Novamill sits in an enclosure which limits how long a workpiece can be even if it overhangs the table. In the other direction the hole position is limited by the throat depth, for at least one hole. So I think I'm limited to direct drilling.

Just had a dig around in my miscellaneous cutter draw and come across a little bag with a haul of 3.5 mm carbide mills from JB, will give one of those a whirl. I have spare material so can afford to experiment.

I thought the Nova's enclosure sloped down towards the front and you would be able to do it with the work sticking out the front? Mounting at 45deg may cure the throat issue if you need to drill a fair distance in from one end.

However the OP manages to drill his holes, I'd be interested in learning about Robertson's clock. The Wikipedia page has a lot of words but no diagram, so less than easy to understand.

As part of this initiative, Professor Robertson’s original engineering drawings will be made available online for the next generation of horologists. The clock was made by Messrs. Brecknell, Munro and Rogers of Thrissell Street, Bristol, “mechanical, electrical, and tramway engineers”.

Been there, a mine of information it isn't. The Wikipedia article isn't much better.

You’re welcome, Duncan

Duncan, I sent you a PM.
