I need an old stop sign, yield sign or similar size sign. Street signs are too small. I need to cut a circle out of an old sign to adapt a pump bracket to a motor. I have a 6+ HP pump bracket which has a larger bolt circle than my 5.5 HP engine. Being tempered, sign is strong enough for intended use. Otherwise, I will have to use 1/4" plate. Yes I know they are every where on the roads and streets. Tomorrow, I will check will local street dept.
