Jacobs Chuck key needed

[reible]

Hi,

Just went out to get one of my chucks to look at. For what it is worth this is the one that came with my 1976 shopsmith:
jacobs multi craft chuck
made in u.s.a.
cap 5/64-1/2
mc8k26
5/8 st hole
hole for key measures .270"

The key is marked as"
jacobs KK

The pin measures at .273"

Edit:
------------------------------------------------------------
I got to one more of the chucks and it is the same as the first.

Dug the last one up and it has a Shopsmith Logo and no other information.
It uses the same KK key.

So I then went to look at my Porter Cable drill, it has the K32 / R5 key. The chuck it self has Porter Cable info with out the chuck number.

So looking at the key the pin is about .246" Dia. and looks long at about .310" long. Clearly not even close to the shopsmith ones I have.

I needed this key and thanks to the great information on this forum, I found a replacement key for less than $5 shipped:

As a follow-up, I received the new key within 4 or 5 days. Interestingly, it was shipped form Grainger. Sent via UPS Ground, they must have lost money on this deal...

Anyway, it fits my chuck perfectly and I am very happy with the transaction.
