Thank you all for taking part, and a happy new year to you. The final amount of layers is 11,424
That is 17 layers, cut to 6 then 4 then 4 then a final stack of 7, before the billet is cut in half and welded back together again.
I have looked through a couple of times....Customfan is closest with 10,000:biggrin:
Well done you! pm me your address and I will send it off.
