Cardboard for making model

[Hwyl]

I'm planning on making a nesting dinghy this winter, it will be hard chine and long and skinny for the type.

I remember people on here talking about a specific kind of cardboard used to make fairly accurate models. Anyone remember what it is?

I've built a boat from stuff called tri-wall.

With good results, I've used regular old card stock and also the matting material (which is available in a variety of thicknesses and textures) used when you have a painting framed and matted. Both are available at crafts stores, where you can go and kinda play with it a little (bend it) to see if its right for your particular model.

If the model is full size or half size you might find the plastic corrugated which goes under the brand name COROPLAST will work. Here is their web site

It is used primarily in the sign industry for signs and in the picture frame industry for backing and comes in a variety of colours and thicknesses.

Any old card stock will do. Just like with wood, it's important to have enough of the same stuff, or a reliable source to do the whole job.

The Yankee Tender was an experiment to see if the flare and rocker matched up to make a straight edge at the chine when unsprung. It turns out that they do.

The Trap Skiff was just to see if I could.

I don't know the actual names of any of this stuff, but I've used enough of it to build a city.

"chipboard" The greyish-brown stuff. You don't need it any thicker than 1/16". cuts fairly well, but tends to eat blades. Glues well. A supreme hassle to paint, but perfectly suited to study-models. Only the darkest beer will leave a stain when spilled.

"butterboard" The buttery-yellow colored stuff, probably made by Strathmore if you're buying in a big-chain store. Cuts very nicely, very supple. Perhaps too supple if you need it to strike a fair curve on its own. Rougly 4x the cost of chipboard, way too rich for an architecture student with a beer budget, but you're probably not using remarkable quantity. Doesn't respond very well to spray paint solvents, but takes brushed acrylics well. Intolerant of beer stains.

For a boat model I wouldn't bother with the foam sandwich products. the rigidity won't be useful to you, and they're more hassle than they're worth to cut.

Bristol Board, just a name I think. Good quality and consistent curves. Made a model of the prospective Thames skiff to test out a half deck and sailing gear position, and get it right in my head.
