Centre-hole guide for belts or straps

[fredk]

Now with improvements

I used the divider point to scribe a line at about 12mm ( 1/2 inch) and 20mm ( 3/4 inch) from the centre. I went over the lines a few times to make it deep enough to take some black paint. I painted the whole line then wet sanded the excess off.

Its on a 40mm wide strap in the picture. It doesn't look even because of its angle in the photo but in the hand the 20mm circle touches both sides of the strap. The black lines are neat too but show kinda broken up due it being a digital photo

Thanks, @chuck123wapati, I was over thinking the problem.  A simple scribed line does the job well.  K.I.S.S. it is

amazing what a guy can do without a computer, a special cad drawing app, a 3d printer........

Another possible mod to it. Use it to mark the first hole, slide it along so the circle is over the mark and mark that point on the circle with the awl. Drill a small hole and put another small pin in it, then once you've marked your first hole on the belt slide it along so the pin sits in the mark and you've got perfect spacing for the next hole.

Just a thought.
