[QUOTE="Timber_MG, post: 180534, member: 18"] Doing them free-hand with a router sucks. Using an appropriate jig it's a piece of cake. I have been persuaded by Chris to make some jigs and will look at machining some. I'd have to either make centering punches for you to mark and drill the holes yourself or do things in a 2-step approach (you mark the base plate and send it back to me for drilling and countersinking the mounting) With a vernier it is a matter of measuring the hole, holding the vernier to the jig, zero and adjust for the difference in radius (diameter / 2), set the jig to the caliper and cut very close to your intended size (0.5mm is very achievable). A digital vernier makes this really easy if you zero the caliper. A normal vernier can do the same job, just that you have to work out the difference in your head. [/QUOTE]
