what is the purpose of these 2 items?

Hi all

The following images are of 2 items that came with the super 7 and we are intrigued to know what they are for.

This appears to be a handle of some kind, homemade/adapted? the thread I think is a 5/16 whitworh, the super 7 clutch ball screws on to it. There is a hole in the end of the large diameter piece which seem to fit the Dewhurst switch on our tool grinder (hope that makes sense). Could it be off the original Myford Dewhurst switch?

Then there's this, I'm pretty sure its a cutter of some kind, does anybody know its original use (its pretty blunt so it appears to be used)

Any ideas will be appreciated

Thanks in advance

Both came with the super 7 not 100% sure what they are.

The second one looks a bit like a cutter to make the rectangular splines that you see on traction engines.

Looks about right for the 1.5" Allchin

At first I thought the second item was the screwcutting indicator …

I agree with Jason, it looks like a special home made cutter for machining the four splines on the second shaft of the Allchin.
