Lathe Indexing Attachment

Hi All

Well i have started on a new project over the weekend ,more tooling  :dremel:, an indexing attachment for the Myford lathe. The indexing atachment was designed by J.A.Radford and i am working from his artical in Model Engineer 5 Jan 1968 (great year)  ::).
I thought i would get the worst job out the way first ,the Index plates ,all those holes . I started with some 10mm plate .



Then i turned up a mandrel ,to mount all four the plates to turn the O/D


Then each plate was mounted and the edges chamferd


The original design call's for a set of 4 plates  7 set of holes on each, just short of 1500 holes , FAR FAR TO MANY HOLES, so after some thought ,i decided to cut the number of plates to 2 with 9 sets of holes and only 525 holes , i wil not be able to index 73,119 173 and other daft numbers , i can live with that.
On the other end of the mandral i turned up an expanding  mandral to hold the plates for drilling.




The other side ,lots of deburing to do

Still some numbers to stamp on the plates


Cheers Rob
