A note to say that I am back in the UK for a few days and have a few more notes that may be of use.
The first is something called 'A Very much Improved Quorn Tool and Cutter Grinder' by a Walter B Mueller which appeared in Home Shop Machinist in possibly November/December 1999 and on.
Frankly, I have no idea how I have a copy- but I have
Again, my very transient memory recalls a Phillip Amos who wrote a series of Quorn Articles in either Model Engineer or Model Engineers Workshop.
Again, I confess to an almost complete memory loss of more details except to relate the sad demise of the writer.
As you will probably be aware Chaddock often mentioned 'something' and a Mr J Hugel wrote 6 Steps to a Perfect Four Facet Drill. Where and all that- I must admit defeat.
Looking through my files, I have another article from modelenginenews.org. whoever it was mentions Derek Brown who wrote on his machine in MEW16 and 17.
I have that series on my files.
Perhaps someone could help you further.
Somewhat bluntly, I cannot because I ran into copyright problems in the past. However, I hope that you will pursue the hints and so on.
