I've tried searching for this topic on so many sites but haven't been able to find it. I want to make my own 9' to 9'3" ish blank and would like it to be out of XPS foam. The biggest this foam comes is 8' so I was wondering if anyone thinks its possible or smart to do this...
Adding about a foot of extra foam to the 8' long board and gluing them together with a polyurethane glue? I was also thinking it might make it stronger if I could insert a small wooden beam into both ends of the 8' board and the extra foot of foam to make it stronger?
Let me know if this is too crazy to try or if you have any advice, thanks!
