Molded vs Moldless Fiberglass Construction. Thread starter CaptainKickback Start date Apr 15, CaptainKickback Lieutenant Junior Grade. Joined Jul 23, Messages 1, While most figerglass the videos show you how to make plugs and molds, some show modeless construction. Here are my thoughts?

Then from the plug, you make the mold, which becomes a negative image of the. Finally, from the mold, you cast your new. There are so many steps in laying up FG, fairing it, sanding, fairing, sanding? Not to mention many, many, many coats of wax, each drying for an hour in between coats. Then, you put on several layers of PVA. Now you have a plug. Then for the mold, you do layers and layers of FG, followed by fixing imperfections in the mold surface, all that waxing again, and more PVA.

Now you? Layers and layers fiberglasss FG, and then probably some fix up on the part? While most videos show putting on gel coat first when making a part, you have a problem if you have to fix any imperfections or if you have to FG the part into a bigger structure. Some videos show doing modeless construction.

The drawback is that some or all of your form materials are left in the. I see several benefits. The biggest benefit is time, and that? Also, some of the form materials may be desirable for strength or rigidity. Since in molded construction in making moldlss plug itself, the surface must exactly match the desired.

The surface of the final part will not be any better than the quality of the plug? So, if mnaual think about it, the amount of work to get the plug surface exact is about the same as if you properly surfaced your form, without a hundred more steps to. So, I? What are your thoughts?

Need be you can pull off multiple parts from your Mold. Plugs are not sometimes used. You have 2 choices here.

Or you can produce a Mold first without a plug. Or you can just build what you build and install it. In which case you have to make a mold. I have built a 'Mold' without making a Plug. Yes it was a One off part. Now that is considered the Plug if I moldless fiberglass boat construction manual to reproduce it I moldless fiberglass boat construction manual have to Mold the part.

Is this what your suggesting? Re: Molded vs Moldless Fiberglass Construction oops! Joined Jun 26, Messages For me, I would have to have a good cnstruction for making a mold and going to all the trouble that entails. If I needed exact moldless fiberglass boat construction manual maybe 5 of something I would find it worth it.

Otherwise the investment in time and material wouldnt make sense. I much prefer making the part or structure in place and in real time. Yea, the stairs and the helm will be one offs. Do you think there's a market for a stair mold? You must log in or register to reply .
