Yes they are finished somewhat nicer than the war time stuff, the links are investment casted then vacuum quenched in order to meet the strict Brinnel hardness scores.
In the end, due to steel costs I couldn’t supply pins at a sensible price, those who were interested were all given options to proceed or not, I am glad they chose to proceed and sort their own pins as it means we were able to do something that hadn’t really been done since the 40’s.
I have supplied my data on pin specs to everyone concerned so they can go and make their own. I can also provide the tooling to press the heads into pins if required.
I know Paul S from the UK is tooling up to make vast quantities of pins, so far as I know he has the tooling setup but is verifying metallurgy before he goes into production…..so there is another box ticked for us all.
I did make some interesting finds on the pin front surrounding pin diameters, to be honest, the whole track link project has been an eye opener on what was made, how it was made during different periods of the war.
