Ah OK.
So are you saying you want to fix it to flog it?
I remember seeing the drawings for some gears used in Radar turning units,
and it was a scary lot of measurements of pitch, and form, ie shape, and
remember the right diameter and pitch are needed before you start or you
end up with half a tooth at the end.

You are not likely to have the equipment needed to do this .

Actually the reason for my query is that last year
I bought a Jacobs gear hobber for a reason that has now
gone and I was wondering if there might be a market
for its sale.

I have a 55 year old dream from the days of my
impoverished teenage years that I would make my
own communications receiver to compete with the
likes of the best at that time, and I intended to
cut gears for the tuning dial but recently have
obtained the rolls royce of dials, the
Eddystone 898 so no longer need the hobber.
