Hi David, my forgework consists of bladesmithing only these days!! I used to be a professional smith who specialised in blades but did anything from making nails, repairing farm machinery, wrought ironwork etc. I use coke as fuel-"smithy breeze" also known as "three washed coke" pretty small pieces about 10-20mm, burns reasonably clean but as Alan mentioned you get clinker. Good fire management is half the battle!!
If you put "meteoric patrem" into the search there's a couple of my pieces and some fellow smiths work too.... Forging keris is fairly new to me my background is Nihon-To based, tamahagane, yakiba and hada!
