Ed,

Thanks for the compliment on the file handles. I got the idea from
Guy Lautard" "Third Machinist Bedside Reader", page 107. The original
was printed in an article by Bob Patrick in "Projects in Metal" (Dec
89, page 8). It has a diagram to measure your hand and formulas for
determining the dimentions for making file handles to custom fit your
hand. Obviously the smaller handle doesn't custom fit my hand but is
really nice for handling those small needle files. I did the first
file handle on my Lathemaster 8x14. The others were rough cut on my
CNC Atlas lathe then finished on my Lathemaster. I spiced them up
some with inlaid brass and copper. The one with the copper end, I cut
a groove with a parting tool then filled it with silver solder then
turned it down and polished it. The brass ferrules were made from
5/8" brass compression nuts from the hardware store.
