Re: Cardinal Mk II Chuck Key
Measure the size of the (probably) square hole in the chuck for the key, then you should be able to find one to fit. If not I can make one.
Re: Cardinal Mk II Chuck Key
This may help? The chap modified a K4 Jacobs chuck key for his MT3 tapered drill chuck. Looking at though you may get away with a 16mm chuck key?

Re: Cardinal Mk II Chuck Key
I should have noticed from the original post that it's a drill chuck, not a lathe chuck :redface:.
Re: Cardinal Mk II Chuck Key
I have a 1/2" cardinal chuck, it's physically the same size as the 1/2" jacobs chucks
I have and uses the same key. I think the jacobs are type 34. I will write down the key
number and measure the diameter tomorrow.
Re: Cardinal Mk II Chuck Key
graffian: did you have any luck finding out any details regarding the key?
The chuck pilot hole seems to be 5/16 [0.3125"] (7.9375mm).
Re: Cardinal Mk II Chuck Key
Yes I had a look, I couldn't find the cardinal chuck but the key I use on jacobs 34 chucks came with the
cardinal chuck. The key has a 5/16 pin and 11 teeth. The key I have is a jacobs and just has
a 3 on it, but it goes with 34 chucks so it shouldn't be a problem finding one.
The next size down key I have, which is for jacobs 32 chucks, has a 1/4 pin and 9 teeth.
The next size has a .375pin and 12 teeth, that is for the jacobs 36 chuck.

Re: Cardinal Mk II Chuck Key
New to this forum so somebody may be able to help. My primary interest is Woodturning but I have a Myford ml 7 as well. I recently got a Meddings MB4 mark 2 drill , very dirty and uncared for but all parts in good order. Everything now back 'as new' except chuck.
It had a Cardinal mark 2 chuck which needs to be disassembled and cleaned. Does anyone have any idea how to do this. On the back of the chuck there is a series of small holes in a circle. Not sure whether it can be 'drifted' apart or if there are threads in there somewhere.
Here are some photos
