Fiberglass help

Hello everybody, I ordered my plans from Don yesterday (Linda Jo) and getting a material list going.I see that most are glassing the hull, with what? 2 oz cloth? This is my first model boat so I'm sure I will have plenty of questions. Thanks any advice will be appreciated.

2oz cloth is far too heavy if you are just glassing inside a POF hull.....you'd find it very hard to lay between and over the frames it is so thick.
You'd be better with a couple of layers of surface tissue and resin.it's a thin gossomer type feel to it and gives (as it says) a very fine and clean surface.

Most of us 'glass the outside, and for that, 2 oz (woven not mat) is great.

far too much work for me to rub down putting it on the outside Pat, especially chopped strand at 2oz weight. I'll stick to glassing a wooden hull on the inside, thanks.

But nhp, model boating is ALL about work!

Actually, this makes me think about another possible technique, wonder if anyone has tried this:

- Two planking layers, with glass in between

Where have we seen this? Well, Elco double-planked their PT boat hulls, and sandwiched a layer of glue-soaked canvas in between.

And the now defunct (I think) Equipage fixed their exploding model boat hull problem with a layer of glass in between two planked layers.

Benefits of doing this?
1. Only rough sanding of the fiberglass layer is needed... no need to take it to a perfect finish.
2. Still serves the function of avoiding leakage should planks shrink a bit.
3. Still serves the function of toughening the hull against bumps.
4. More easily allows for visible plank lines, should you want to do this for scale appearance.


Whaddya think?

a very interesting concept Pat.......I don't think though that I could work to that precission to get a sheet of grp in between two layers of timber planks without a lot of sanding.......and I always say why make work for yourself if you can find an easier solution.

Hi Neil,

I don't think Pat has a sheet in mind, but just a layer of glasscloth and epoxy.

I do agree with Pat, modelboatbuilding strongly resembles work..., but I like it more than my day job.

With a little planning, glassing a hull doesn't take a lot of time, it's the curing of the resin that takes much longer...:

I didn't mean a sheet as such, but I call a leaf of paper a sheet.....suppose it's just my way of saying a "layer of"

I just glassed my first boat kit using Pacer Z-poxy resin and Sig 1.5 oz/sqyd cloth. You can see pictures of my build under the build log titled, "Garwood Speedster - My first kit".
