Endmill Sharpening 

Paul You do not mention which book you are working from. If “Milling a Complete Course” you will find on page 114 the statement which says “Fit bearings using two part resin adhesive. Therefore the bearings will get slit at the same time as parts 63 and 64. Incidentally, I wrote the article for the “Model Engineers Workshop” magazine starting in April 1992 (when I was editor and short of articles) and then published in “Milling a Complete Course” in 2004. If you are looking at “Tool and Cutter Sharpening” look at page 110 for a similar explanation. However, this book deals primarily with sharpening techniques and has much less detail about making items. Harold

As it would be a one of and not mass produced, very expensive, at least £ 200.00 I would think!

Both for taper pin and Morse tapers reamers the angle needs to be very accurate, I doubt if this could be achieved. Also for Morse tapers the required length of the traverse would be difficult achieve without fluctuations. Harold

Thank you very much for your quick response. I have two of your books and have begun making some of the tools. I have a long way to go before I'll be making reamers with custom tapers. Happy New Year, sir. Bill
