Hi,

I hope one of you very knowledgeable chaps can help. The tailstock barrel on my Mk.1 Super 7 has started to rotate. When I took a look on mine the key lock is a two piece affair which appears to be inserted from the outside and wedges together and looks like it has worked its way out a bit. It does not look particularly worn. Would I be right in just tapping it back into the hole (aligned with the barrel of course)?

I also remember buying a replacement bit to make an order up once but this looks like it is inserted from inside the barrel. Is this a later modification in how this works?

Apologies if my explanation is not very clear.

Matt

If viewed from the side, the barrel lock is T shaped. If it's lost the 'ears' you will need a new one. Fairly easy to make.

Sorry, not clear. The item is one piece, yours is broken.

Hi there, MattK,

The Mytholmroyd Myford web-site shows that the tailstock keys for the Super 7 and the ML7 are different. In fact, they give two separate part numbers for the ML7 key.

I suggest that caution is needed here!

Best regards,

Swarf, Mostly!

Thanks for the replies. Very helpful. Interestingly the spare that I have (which I managed to find) is one piece and has the 'ears' as described. The one that is in there though was clearly designed as two pieces and is not a broken version of the spare I have. It is similar to the replacement without the ears but the whole thing cut diagonally so as it is tapped in it would tighten in the hole. I wish I had taken a picture now but I tapped it back in and the barrel won't rotate now. If it works loose again I will see if my spare fits.
