How to make a circle (no center hole)
I have a small task: make a cover of an access hole in my kayak, since I lost the original rubber cover. My idea is to make it from clear plastic, since the hole rim has threads for screws.
I think the router could do the job.
Finding a circle jig is not really an issue: just drill a hole and rotate tool around it. But.. since this is for water-use, drilling a hole is a bad idea.
So any nice tips on how to avoid this center hole ? I would like to have a perfect circle at the end.
FYI: my workshop is very small, and I only have a std. plunge type router for the job.
