Turn the Dremel router upside down and lay the MOP against the drill bit on top of the Router base of the UNPLUGGED Router. Now set the depth so that the drill bit is even with height of the MOP. If you set the depth so that the drill bit is higher than the MOP, your inlay will end up BELOW the level of the wood surrounding the inlay. To fix this you may need to add 'saw dust' beneath the inlay. If you set the drill bit to slightly below the MOP you can sand the MOP down and get a perfect job with a little more sanding than is necessary! Hence try get it exact. The 'thickness' of the super glue or Epoxy will potentially allow the MOP to protrude slightly so that is can be sanded level with the wood around the chamber.
Make sure the drill bit is secure in the router collett and that the depth controllers are tight as you don't want to find after you have drilled that these released and you now have a 3mm deep chamber instead of a 1.1 mm chamber (if you used 1.1mm blank MOP!
Now turn the electrics on.
Set the Dremel to 25000 revs, and be careful.
Work from the centre of your inlay outwards in an anti-clockwise direction.
Be especially careful at the edges where your lines are drawn. A slip or loose grip could see the dremel careering across your headstock!
