< You can get replacement screws from Bernerds, can't remember how much they cost me when I did this some time ago. Since then I have discovered "Rotogrip" - a company that specialises in chucks and spares for chucks. I have found them very helpful. < Not connected to them but a very satisfied customer. They are indeed helpful indeed and if you look them up a the end of the day willing to have a chat and free advice. Aside from the eye catchers and cheapies they sell the real decent industrial stuff. Their stand is certainly worth a visit, sadly enough not present at every ME exhibition but usually at the Engineering In Miniature related ones.
