Boat jigs

[Fishovertime]

ADVERTISE HERE

Brokensheer,
I love,love the C-Flex almost zero wastage ,takes all the reverse curves ..etc so much easier than the foam I used on my 27'.
The price was also much better than the corecell...This thing was a piece of cake to put together,and so was the fairing.

Good for you Andrew, I had some issues with the first laminate over the cured wet out seeflex, it just moved too much allowing for air to enter the laminate form the underside. I spoke to Dave about it and he made me understand it was just a condition of using the product, I agree with your other points, I just spent what I thought was too much time grinding out bad spots,, Best of luck!, does the boat have a name yet?

So has anybody finished a CBBoatworks jig? Any performance information? Are they naval architects? Where did these guys get their training/experience? Sounds like they have some happy customers.

will let u know soon. will be starting the 32' they also did a 24" tuna door, top decks and all the inside and out. soon will see, soon will see.....

No name yet...Still a couple of years off that!
We finished the fairing off today ,so hopefully its the epoxy primer soon.

Can you guys explain the difference in c flex and cold molded. What are the benifits and drawbacks of each build method and boat charateristics?

Seaflex (seeflex)is a big roll of fiberglass that has very small continuos fiberglass rods in it .it is 12" wide by however long you need it to be, it allows you to begin to lay up a hull over mold frames ( jig ), The solid continuous rod allow the fabric to span a distance over the mold fram without sagging,and when you do so and the polyester resin cures you can apply the additional layer on top, you will then apply a fairing compound and fair ( sand) untill your hull surface is what you deem acceptable, then turn the hull over and wet out the inside and build your fiberglass schedule untill you get the complete hull glassing finished much easier less skill required then cold molding polyester resin is less expensive then epoxy too, pleanty of boats are built with polyester, epoxy is stronger!

Cold molding is a term that came about when epoxy resins mo longer had to be heat activated and began to cure at a given room or ambient temp. the turn in boat construction as it has become is to build mold frames same idea at with seaflex but this way are covered with thin wood veneer or thin plywood glued up over a jig with epoxy resin the laminated of wood are typicly applied in 45degrees to the keel, then 45 degrees in the other direction and so on, this method of construction make lighter and stronger hull but requires some fiar to mid knowlege of wood work and how to get the peices to fit tight next to each other,
alot of building in this way has become regional due to the availability of raw material, you could find a good bit af juniper in the Carolinas,,

Dave Sintes is the guy who helped bring seaflex to the fore front and has instuctional media on how to use it, the book Gougeon brothers on boat construction should help you better under stand wood epoxy construction
Note I hope this answered your question and I am sure many more will comment , this subject is huge and to get a solid understand will require some studying on your part I hope this helps
