the watts brothers tool company makes a cool drill bit/holder that will make "angular" holes - for example a triangle, square or hexagon - there was an article on this tool in one of the hobby magazines (current issue) - a friend gave me a photo copy and asked that I look for the manual - after some searching found it, along with a statement that the company would be ok with it being on line, so it's out there for you if you want it -- look for files beginning with Watts in the drop box - they are there now. I've also uploaded the first patent related to this technology so you don't have to dig it out if you are interested. it looks like the manual, which is a 5 meg file hasn't made it out to the drop box yet, look for a file called Watts Bros Manual - I uploaded both a doc and pdf file, they are the same content but not everyone has MS Word. The file size would shrink dramatically if someone were to OCR it, right now it's just page images.
happy reading.
