I have a rather old indexing chuck, it is horizontally mounted and has 36 indexable positions, so is good when i need to drill on a radius as I can quickly index for 3, 4, 6, 9, 12, 18 or 36 holes if ever needed to.
It was given to me years ago as a swap for a small diving head suitable for a small Myford.
Anyway, during my tidy, I have decided to clean it up and give it a lick of paint, but I need to replace or preferably repair the bevel gears as the square holes are nearly round.
I can tell it is old as it is not a Pratt Burnard, just a Pratt chuck, it will have to sit is electrolysis for a while to get the surfaces clean once the dried up grease is removed, but I digress.
here are two pictures of what I mean.
Now I can not shape an internal blind hole as I have no kit to do so.
I turn probably use the lathe to turn the hole to a circle, and what I was also thinking was to use some old 3/8" or 1/2" sockets and again on the lathe turn own the ends so it would be a good fit inside the bevel and weld the socket end in there.
But I am open to ideas if you have thoughts on this?
