As soon as get my machine on "15th", I'm Going to get the single one milled out( my mates in the engineering Dep @ work) If it works out ok (I'm sure it will), I'll post a pic, (If I can work out how to post pic's),and its only going to cost me a Six pack, I'm sure if you want to use one of yours, I could get him to do the same, pretty easy, We make tooling out of solid s/s and brass all the time, mate thinks it should only take 10-15 mins.
