Hey John, realise this is an old thread but I have exactly the same situation / desire to upgrade to a chuck on my old 571 .... did you make any progress on this?
Hey everyone. I have an old style green Sedgwick morticer, which for those unfamiliar doesn't have a chuck to hold the bits like the newer ones, but rather uses collets. I'm thinking about changing to a chuck and was wondering if anyone has any experience of doing this?
It seems quite a small...
