    Does anyone on this list have a copy of the Workshop Practice Series booklet "Gears and Gear Cutting" by Ivan Law? If memory serves me correctly, he showed a simple jig for copying spur gears in a shaper by using an existing gear as a pattern/guide.

      Al, I have that book. Fascinating reading...especially a double eccentric device for making form relieved gear cutters. I don't have it readily at hand right now, but I don't recall any info about shaper cutting specifically. I'll try to remember and look again tonite.

        Just got the book out and had a look but found no mention of shaper cut gears in Ivans book.

        I've been a bit at sixes and sevens having just redone my office and some books and info haven't been to hand but whilst also looking thru backup CD's afer a reinstall of W2000 I found the movie I made some while ago of that cutter relieving tool described in Ivan Laws book as the Eureka.
        I've put the file back on the web at:-
        Not very good quality so I must apologise in advance but if you look carefully in the background you can see the chuck jaws rotating in real time. I set this up on the lowest speed so you can see it as clear as possible.
        It's a staged shot and the tool is not the button type cutter but just a parting tool put there to show how it backs off per tooth.
