Driver Cutout Tips

[Francec]

I've built a circle cutting jig for my plunge router based on the attached. I've added aluminium guides down each side of the base plate and it is very secure.
What I need is a pivot pin; one that canned be screwed into place into several points along the length of it.
Does anyone have any suggestions, please?

Bump for suggestions.

Why not just a simple wood screw with a round head? Standard nails will work also.

See the picture of my plywood circle guide. Just a slot with a T-nut and a bolt. Infinitely adjustable. It needs a relatively big pivot hole, but it fits securely with very little play.

Apart from that... stick a bolt through the T-nut and lock it in place with a wingnut.
