GO FOR IT!!
My buddy Mike and I have shaped several boards. No matter how it turns out, surfing your creation will make your day! I am by no means a pro and every time I look at my boards, I see things I need to do better. Especially when I compare them to professional shapers boards... I am actually making my first Pawlonia board from a tree I grew myself, actually, I have to call the kiln today to see if it is dry enough yet...
Your first call should be to Greenlight Surf Supply. Brian is super helpful and really good with answering the phone/email for questions. He has kits and everything to get you started. Make sure you get the vented leash plug he invented too. All your wood tools will work on foam for sure.
