Where can I get info or a link on building a plug and mold or a fiberglass boat hull and deck?
I'm looking for a "how to" step by step process.
I've worked on and restored many boats but never built one from start to finish and would like to build a very limited production, small power boat.
Thanks

Itchy- let me know if you would like info on what NOT to do when making a male mold. I'm an expert there!
In my limited experience, I would definitely say that making a plug and female mold would be the way to go if you plan on making more than 2 hulls.
My arms are sore from longboarding to try to get a smooth finish on a hull built off of a male mold.

Info on what not to do would be just as valuable. What type of boat are you building?
Any info at all is very much appreciated

Building a shark catamaran. Many of my mistakes were in building a male mold with not enough "Beef" . Whimpy often means warping. Build it with the right materiels the first time, and you will save a lot in the long run.

A plug is a excact replica or prototype of the finsh boat you will spend most of your time on the plug ,get it right and defects will transfare to the mould and every boat will have your signature on it,

Thanks for all the info. I'm really looking for some pics and info on the process of building the plug. I've got the basics down but trying to get all the info I can before starting on a big project like this. Also trying to keep the trial and error to a min.

Available only from Cook Composites for around $100.
Valspar also has a less detailed publication.

The Cook Book is also on CD, if you give me your email address I'll try to send it to you. You'll need a high speed connection though, it's big.

Hello,
I have been reading this forum for several weeks. Lots of great information here. I build and repair inflatables and RIBs in Toronto. I am always interested in learning more about composites. I can't find any reference to the Cook book on their website and none of my suppliers are aware of it.
Can I ask for a copy via email too?
Thanks, DB

They are very expensive to publish and hard to come by, only good customers get them for free (book form), the CDs are handed out more freely and Composites One might be able to get you one. Just looked, you're in Toronto, so it would be Progress Plastics. I don't have any books left myself, and only a few CDs, but I do have an order in for some.
