The thread is 4mm diameter, so first we drill a 3.5mm pilot hole to the required depth (this depends
on your machine screw length) the we screw it in using a normal screwdriver to start to cut a thread
into the wood.
Then unscrew the screw, put it in a vice and cut the head off with a hacksaw.
Screw the threaded part into the knob and it can then be screwed into your pilot hole.
However…...our project is round and the end of the knob is flat – so before fixing we drill a shallow
8.5mm rebate into the drawer to inset the brass knob slightly so it appears to fit perfectly.
The final part is to take the box back to the pillar drill and drill the 45mm hole all the way through
the top of the box, mark and drill the pilot holes for the coffee grinder mill kit and bolt it on.
You then have a completed box with drawer and a quality ceramic grinder that is sure to impress:
After all that you probably deserve a cup of coffee!
