The process of molding?

[andreasmehlin]

Richard: Thanks for the input

I would be glad if I had some people helping me out molding it. I just need to find these guys

What part of the boat is it necessary to build solid fiberglass to withstand high pressure (like the mast stand)

Some good advice there Richard, but just to explain one of your comments -

"NO it makes the opposite! Though rwatson was right, it holds down single fibres of glass. The reason using it is to have a as rough as sensible surface to get the next layer sticking without sanding!"

The surface left by peelply *is* smoooth - compared to not using it. True, it is rougher than say, a polished surface created by a mould, or using Mylar, but the peel ply finish is much smoother than hand laid up finish. It is as smooth as satin, because it is basically Taffeta cloth used for dresses.

Richard has a good point about getting help. This is a much bigger project than an inexperienced single person is generally recomended to try.

Re the mast support layup - all boats designed properly have a "layup schedule" in the plans. This gives you detailed instructions on every piece of Cloth used in the construction, including building mast supports, chain plate backing, winch supports and a million other things.

You would never start a project of this sort without that schedule , and the plans.

I´m actually not sure if there is any schedule how detailed the plans are, but I hope there is something...

The boat was designed by a norwiegen with help from John Shuttleworth.
Not sure what is common to do when designing a boat, so not sure about how detailed the plans are.
What I know is that 6 boats is beeing made and have reached different stages.

Yeah I know it is a big project and I wont start it within a year. Need to learn more first and do some smaller projects first.

Nothing is decided yet and am still investigating everything about the boat and the moulds. Not really sure how big the biggest moulds are. I think each hull is devided up in servral moulds.

Well mate,

>>>>The surface left by peelply *is* smoooth - compared to not using it.<<<<

in technical terms it is rough! As rough as a sanded surface, and that is the reason we use it! It provides the mechanical grip for the next layer on that cured surface.

And I agree, the layup plan has to be provided by the NA not here by us!

A good overview of peel ply is found here

To jabber on about peelply:

From a macro perspective, it gives a smooth finish. More smooth then hand laminating.

From a micro perspective, it gives a rough finish, which helps getting the next layer to bond.

About a laminating schedule: You would really need a naval architect for that. It is virtually impossible to get the info you would need through a forum. Perhaps the general layup can be determined, but detailing stuff is more difficult. It also depends on skills and previous experience.

Thanks fot the input.
I understand it is very important having a good and detailed lay-up-plan, so lets hope there is one cause I don´t think I would do it without.
