Installing Base Molding
okay, cut a 45 in the end, (the run would come to a point) cut another 45 opposite to that, that is a typical return... you would use that cut to step down similar to a crafstman stye to got to the height of the existing base... then again it's hard to figure you exact situation out too, so that may not work for you.
If you want you can post a picture on my web sites forum and link it here so we can see what you talking about...
Can you describe it better Mark? (If you know what I mean that is? )
