« Part 3: Simple Circle Cutting Jig for the Routing Table Part 4 of Jigs etc. series no next part

I’m just going to let the pictures tell the story here. The only things I will say is that the template guide pin must be exactly the same width as the router bit used (6mm in this case) and the minimum hinge pin width is also dictated by the router bit used. This is the test run with a 115mm square x 6mm thick piece of MDF being routed. No, even I don’t trust the actual pieces I am working for a project to the first run with a new jig.
The templates were marked out, using a knife, on a single piece of perspex (plexi-glass), the sheet cut in half and opposing ‘fingers’ cut out. Once these two pieces mesh all joints routed with them should fit and be identical. This jig could also be used for finger joints (box joints).

The name, as with most of my jigs, comes from things associated with atomic weapons and their testing. Not in glorification of this but more in the hope that something positive can be achieved under the same name.

That’s a fine precision jig Martyn.

Incidentally, something very positive has already been achieved under that name ;-)

Wow! Thanks for posting this Martyn! So much work went into that design that many don’t realize it. The jig is very clever and it is nice that you take the time to share it with everyone. :)
