So this guy calls me and wants to put address numbers on his monument sign and would like me to come and do an estimate as soon as possible. I say no problem and hop in the truck and drive a few minutes to his site and then I see this! He wants to have an insert put into the cavity and then wants numbers for the building put on the insert. I have never dealt with a curve like this before. Not only is the sign curved but also angled . Kind of like an upside down "funnel" for lack of a better example. I have all kinds of ideas about how to fasten the sign to the concrete and hide the screws, etc...but what I am trying to figure out is how to make the insert for the cavity. Or more specifically, how to make a pattern or jig for the insert. Do you guys have any experience with this type of thing. How do I make the pattern or jig for this?
