Duh. Would help to finish typing before hitting send...

For the grooves I would grind a form tool. Basically just the wood
chisel idea, but ground from a blank with a grinding wheel. Pick up a
few blank bits at the local machine tool shop so you can shape things
however you need. The boring bar I use most often was made from a 1/4"
blank in about 10 minutes and does a perfect job on holes from about
3/8" up, for example. Grinding tools is something you should learn as
soon as practical. Makes life much easier.
