Excuse me for interfering, Dave

Is this the Greenands topic that you seek ?

Depending on the required accuracy and surface finish, a band saw with end stop would be quick.

If I were your customer I’d be looking at commercial alternatives readily stocked, such as dowels or (if a hole through it, or some other objection, doesn’t matter) a roll-pin. If necessary modifying the design a little to be able to use such items.

An alternative to a band-saw would be a metal-cutting circular-saw or cut-off grinder, followed by a quick twiddle on a linisher to blunt the cut edges. (I spent eight years cutting machine-ready metal blanks, of all types, for a living… It’s a wonder it didn’t put me off model-engineering!)

..any use..?

Thank you Nick Hughes, I have been in contact with Dean at EKP supplies. This company have the correct machinery to manufacture my product.  I have now placed a contract with them.

Not sure why all the complication!

What Lawrence is asking for sound remarkably like Dowel pins. Dimensional accuracy is way better than  his requirement.  If I understand the specifications Din 7 ones have domed end, ISO 2338a are flat ended with a small chamfer. There seem to be lots of places that sell these in various combinations of material, diameter and  length.

If I were looking for a few, I might put the time into making them. But at 100’s off the ones available on the net look very reasonable. E.g. 10mm long in a pack of 100 €10.87, and I only spent 5 minutes searching!

Sorry Lawrence’ final close crossed with my typing.
