We have some very handy flat aluminum extrusions that Lukas saved from the trash because of their jig potential: they can interlock with each other at 90 degrees at any length!
Before assembly, you will need to calculate the desired inside measurement. This depends on the way you'll use it:
- using a router within the jig:
inside(jig) = inside(hole/recess) + router base diameter - router bit diameter- advantages: maximum depth usable, clamps are not in the way of your movement
- disadvantage: large enough workpiece area needs to be availabe (easier with a palm router), router bases are usually not evenly round
- using a router with copying ring on top of the jig
- please double-check, not tested!
inside(jig) = inside(hole/recess) + copying ring diameter - router bit diameter - advantages: even guidance no matter how you turn the router, also works close to the workpiece's edge
- disadvantages: harder to clamp the jig down without obstructing the machine, loss of routable depth, only possible if copying ring is flatter than the jig
- please double-check, not tested!
Then, make sure to clamp the jig down securely before starting your cut and you'll get great results!
this router jig can also be used with a jigsaw, but at least the corners won't turn out nearly as nice
the jig is very handy if you need slots that are a bit wider than your router bit
Future Improvements
- it would be very handy to keep a dedicated Torx key in the same place as the jig
- maybe we could add precise rulers for easier setup - e.g. glued on or engraved somehow?
