I have a broken Albrecht 0 – 10mm drill chuck, following a "youtube" video I have now got it in pieces. Unfortunately the small locating stud is sheared off, only a very small piece is sticking out, nothing to grasp onto. My question was the stud threaded or was it just a harden dowel. Any useful / practical suggestion on how to get this valuable chuck back into use will be much appreciated. John

Assuming that you are talking about what this link :- **LINK** calls the drive pin it appears to be a simple plain pin / dowel.

The link that a roll pin is an adequate substitute. Fully rolled spiral type (Spirol) would seem a better option than the usual simple split tube but I don't know where to get small quantities or, better, a boxed assortment in the UK. Personally I'd use proper solid dowel.

AHC of Camberley Surrey stock a range of roll pins. (usual disclaimer)

Norman has the right method. Solid silver steel pin. Needs to be nice fit but otherwise straightforward.

To close the OT drift on Spirol pins.

A UK retail source is :- **LINK** . An ordinary split tube roll pin is unsuitable for that sort of overhung application as it will crush and deform under any serious load. Doesn't help that most of the inexpensive import ones usually found retail are way, way weaker than the specification. Spirol form have inherent internal support.

Metric assortments can be got too :- **LINK**. Not cheap but I shall be saving up!

I've got the chuck up and running once again. I didn't realise that they were so expensive, made me cough and nearly choke on my corn flakes. I used a small roller from a broken needle roller bearing. pressed the broken piece out, new roller in and cut the surplus off using my Dremmel. Though I'd tell the story as others might have the same problem in the future. John
