Good morning Overs.
DG - sorry to hear about your broken nights sleep.
On Wednesday I was trying to make a jig to do a repetitive job quicker. The arithmetic for setting up a power tool wasn't hard but it defeated me, so I thought I'll do it by hand. Finished it and went to cook our evening meal. Thursday I go to use it and discover it is too big!
Puzzling what I'd done wrong I discovered I'd made a jig exactly the correct size to make the jig I needed.
Have a great day.
