Bernico Question

[Ian]

This may be a really thick question but here goes anyway


How is the Bernico moulded, where is the join normally found on the rubrail ??

 

[Ian]

Lovely lookin boat....by the way Cyco

 

[BREN]

i think they are built the same as the cougars 225 laminated together on the inside and then gel coat filled on the outside flatted smooth and polished up.but i could be wrong?

 

[Burty]

Bren is right, this is an extra on Cye's boat as none of the other Bernicos that i know of have it. apperently it took Nico ages to get it right. I'm sure Cye will tell you more when he reads the post on monday

Same principal as a canoe

I would think this is a "split" moulding, when the hull and deck are layed up the two moulds are bolted together then gelled from the inside then bonded up. Then moulds are extracted from the boat leaving a "seam" to rub down and polish.:wink:

Cheers guys

gav
is this the same way the cougars 225's are made?with the moulds been joined together etc

Bren,

??I would have thought so........... i might be wrong and way off track, but to me its really the best method to ensure the two halves meet perfectly, if it was a flanged mould you would not be able to guarantee the edges meeting..........

 

[BREN]

i looked at a cougar and when the light caught the side i could just make out the join line where it had been gelled together.
can they be joined this way with any gel colour?i think the cougars are only produced in three gel colour colours any other colour has to be painted.i just wondered if some gel colours would be to diffucult to hide the join compared to other gel colours?

same way as a batboat

 

[kitten]

there is a rebate formed in the top edge of the hull and the deck is fitted over that and glassed inside then faired outside. The finish is 2 pack spray paint.

You can if you build your moulds right in the first place, it just takes more time.

so if the is painted in 2k does the outside join get filled with gelcoat or body filler? i would have thought body filler would be the easiest and quickest to shape and rub down etc?

 

[kitten]

Not too sure on the exact filler, but you are right it would be too much like hard work to use gelcoat.

But if filler was used any stress on the hull would easily crack it??

 

[kitten]

Depends on the type of filler.
Anyway pure standard gelcoat in a lump is about as brittle as it gets, so that would crack. It's all about the right matirial for the application.

Pascoe used a rebate along/across the join on the V24's, the rebate was to accept a couple of layers of cloth tape to help stop any cracking, then a gel repair right round the boat, no paint!

i suppose that takes a lot of skill to do this if theres no paint to hide anything
