Alan, at the risk of further uncalled for remarks about having more than everyone else's alloted time- and what to do with it, Professor Chaddock made a MillDrill on a mangle of a Drummond lathe. He then set off to make an model aero engoine from solid and found that the 1/10th milling cutters were crippling him in replacements so he made them on the Quorn. He confessed that he could not actually re- sharpen them but making fresh ones is more ideal.
I wont be at the next ME Exhibition. One it is too far and two, I am ancient at 77 and have seen it all and three, I have property to check on in the North of Scotland and four, I am far from well from having a bug having been in France, HongKong and Dubai in the past few weeks. And secondly, I am too mean. I have no doubt that the SMEE will be there and if not, there will be plenty of Quorn constructors and 14BA folks to question.
Shooting off to a further tangent, my mate who has a hybrid Stent with Quorn overtones has fitted a Dremel into the space occupied by the Quorn spindle.
I think that this unpunctuated answer will suggest the way to go.
