How about using a drawplate?

Pinion steel is hardened and tempered to a similar hardness to alan keys .

Nicely done so far.

A word of warning though, all the blue steel wire that I've bought has been very hit and miss. The sizes aren't super accurate and especially the hardness varies a lot. A few hundreths of a mm won't make any practical difference in a clock this size, but I'd be more worried about the heat treatment of the wire.

A lantern pinion won't be ideal no matter what you do, but it certainly is good enough. However it is important that the wheel tooth form is corrected and the depthing done properly to ensure as smooth engagement as possible.

Have you thought about using drill blanks for your pinion wires?

And stupidly it is cheaper to buy the actual drills and use their shanks than buy specific drill blanks  :scratch:

If your pinion is small enough that the shank works; I don't know how much you need.

https://www.mcmaster.com/2900a219 will get you a hardened and ground blank.  I don't see anything longer, though.  Sorry!

Drill blanks are available here https://www.drill-service.co.uk/products/drills/drill-blanks/blk-hss-drill-blanks/


Another alternative and useful source of small size quality steel is sewing machine needles
