I have to agree with Jared.
I would talk to this Dave Lewis or the guy’s from Kook & Hackle to make sure you are getting the action you want, but by all means, go for it. As for working time for a beginner, I would say 10 to 15 hours. Just take your time with it. Assemble the real seat and handle and make sure you are liking the way thing look before you glue them into place. The same with the guides, if you don’t like the way the raps look, cut them off and try again.
Good luck with it and let us know how it turns out.
