check ebay, they have alot of templates for sale there, or just type it in google and search, you'll be suprised with the outcome. Is this the first time making a neck through? i suggest you practice on mdf or something before doing the real thing, even with a template you will make alot of mistakes. Making a mistake on a neck through would be painfully cost worthy if you could not undo it. Get your practice in first untill you think your ready.
