The Birth of a Grub Screw

Then it needs setting up in the newly repaired EDM machine and a hole popping
awemawson:
Now I decided to sink in 10mm - the original was 25 mm deep - far more than necessary. Take about 15 minutes so while it was at it I went off to put the window back in the Goose shed that was blown out in last nights winds. The machine has a micrometer 'stop cutting' adjustment so I left it to it.

This was the result
awemawson:
All together a very satisfying mini-project that went smoothly. And the need for the grubscrew prompted me to fix the EDM machine  :ddb:

Pete.:
Very cool. The only way I could have done that is with a rotary broach I think.
