How the heck do I drill a hole through the width of this resin casting? It has to be perfectly level and square because it's for the dive vane operating shaft.

Do you have a pillar drill, Richard?

I only have a hand operated drill David, all that sort of thing was sold off by first wife's solicitors...the complete contents of my workshop/two sheds/garage...all gone.
The only power tool I own now is a cordless screwdriver...

Thank you Andy...bit of a rethink going on now. Apparently the original Bibers had the rudder and dive vane made from wood, so I'm contemplating replacing the cast ones with wooden ones, that way I can build in the operating rods as I go. I think...
I'll let you know mate..

You could do it carefully with a hand drill.
Clamp the vane square on a table and squint along the hand drill as you do it.

I had thought of that David, but it would be a last resort.
I now have two choices, I think...either go scale and make a wooden rudder/dive vane, or get Mark(MMB)to cast me a completely new resin dive vane with the operating rod built in.
Decisions, decisions...

Just had a very interesting email from Harry Brash regarding this:
This is his solution (he had problems uploadng pictures) so I've posted this on his behalf.
"Hi Richard
I've just spent 45min trying to reply to your post re drilling a hole. I just couldn't get it to accept two photos.
My approach to your problem is to create a jig. If you look at attached "PCB Spacer" I have soldered a 6BA untapped spacer to a piece of PCB. You have to press down on the spacer when soldering to make sure of good contact.
Then in "Drilled" see the clamped test piece of perspex which I drilled through - electric hand drill with test piece and jig held in vice. In this case it was a 3mm drill, the test piece was 300mm wide by 6mm thick and the hole 'drifted' about 0.5mm from one side to the other. Probably do better if not drilling perspex.
Obviously you can use whatever is available to make the jig as long as the drill fits the spacer/tubing very well. The good thing is that you can try it out as often as you like before you drill the one bit that matters."
Many thanks for that Harry, much appreciated and a simple idea.
