A quick wipe with celulose thinners and the patterns fall off Paul, but until my replacement saw comes I am stuffed, Axminster phoned today they have no more new EX16's in stock, the one they were going to give me was damaged in its box when they opened it. So they have tuned up my last saw I had returned with vibration probs and they will send that to me till the new batch arrives end of April, but they said they having trouble with the North/South blade movement, the smallest they could get it was 1.8mm.
By the way, did you get the email I sent you the other day Paul?
