Diamond Dowel Pins

[AdrianRParticipant @adrianr18614]

I needed to dig out the information about Diamond Dowel Pins to give to someone and thought I would pop it on here too as they are quite useful.

They are used to allow alignment between parts where the dowel holes may not be perfectly aligned. You use one normal pin and one diamond pin.

Rather than give a manufacturer link, just google "diamond dowel pins" if you are interested.

A useful Idea to tuck away at the back of your memory for that difficult job. And if needs must they can be knocked up on a grinder.

Diamond location pin is used in tandem with a full pin for location of a part with two or more holes. The diamond is angled so that the point of the diamond is inline with the two holes, this gives maximum distance tolerance allowance across the two location holes. Used in production fixturing and available at all good engineers fixture component suppliers.
