I can't believe I just found this thread ! About four or five weeks ago a friend of mine sent me a link to a machine that he was considering, very similar to the machine you are building ! The only thing that concerned him was the fact that it would be coming from foreign shores, (vat, customs charges, shipping etc) I must point him towards this thread and see what he makes of it. Anyway, here is the machine he was considering, as you will see, the similarities are there
