I used to use Jenkins for steel billets for the lathe. It appears they no longer do this. Can anyone point me in the right direction to another supplier? At the moment I am looking for a piece 200mm dia x 90mm.
I use m-machine-metals.co.uk. Not the cheapest but a good range in stock and the quality of the steel is good (I've bought dodgy en8 elsewhere that ate parting tools for breakfast).
They have black en3 up to 260mm, sold by the inch (or 25mm!), cast iron to 300mm.
