Topic tags/keywords: rounded corners routing template tip trick

I’ve been looking for ideas online about how to accurately cut rounded corners. The standard method of doing that appears to be tracing a coffee can, removing most of the excess wood, and then sanding to the line. Some people do that to create a router template, or to do the actual rounding itself.

That seems like a nice idea, but I don’t have the sanding equipment or skill necessary for it to work especially well. I think an alternate approach to rounding corners could be to grab some spare CDs, and use those directly as your router template.

3 CDs would give you a 1/8” plastic template, and 6 CDs would give you a 1/4” template. Glue them together, and you’ve got yourself a perfect 2.5” radius rounding template. The CDs have the benefit of being sturdy enough to route against, as thin or thick as you need them to be, and they won’t ruin your router bit if you should happen to run your bit into them.

Attach with double-sided tape, and route with your preferred template routing method.
