I've got to make some escutcheon plates for a euro cylinder to be laser cut in 3mm mild steel.
I found this drawing on line.
I'm not sure how much bigger to make the cut, my gut guess is 0.05 - 0.15mm, but I really don't know.
I guess it might be a little trial and error to get the perfect fit. Maybe I should send a few alternatives in. Please could someone advise.
