Motorcycle clutch basket refurb

[olderdan]

A device similar to your suggestion was made some years ago designed by a very clever chap who joined our firm from BSA, this was made for form grinding helical gears on a standard surface grinder.
It worked on the principle of a stationary drum with a spiral groove containing an air cylinder and the traverse was controlled by air valves the grinder bed remained stationary.
He even worked out toe and heel compensation for a set wheel diameter to get the correct form,(tolerances were tenths), and did all this on a Hewlet Parkard calculator (no computers in the shop then).
He was a really lovely guy to work with and was much respected, sadly so longer with us.
For myself, I only have occasional use for something like this so I will stay with muscle power, I hope we will see a posting of your set up in the future.
