foam core + Qs

Postby fluidboards » Mon Apr 14, 2008 6:14 am

Hey guys,

Getting started on my first proper board (built heaps of plyboards over the years).

I'm thinking about using a PVC foam for the core, simply because it's easier to get hold of and cheaper than corecell. The site says the product is suitable for marine use and is water resistant. I'm thinking of ordering some 10mm sheets.

As for vacuum bagging, I'm currently working on finding the peel ply (although I have heard that you can find materials with similar properties for a fraction of the price - coat lining etc...) and also tracking down suitable plastic. What stuff should I be using? I'm thinking the most important property of the outer plastic is just airtightness, right?

I found this site: http://www.roarockit.com/rc_wood.php

Has anyone had any experience with these? I would have to order a custom size, but they still look pretty effective.

I'll be using a silk sheet in the board layup for graphics, although still considering buying some PBT for the next one...

epoxy siderails, 18oz of fibreglass cloth...

I've read through most of the stuff on this forum... any final words of wisdom before I take the plunge and start killing my braincells with resin 8) ?

Cheers, Will

How hard is it to run the pump from AC power? Is it simple enough to wire it up, so it runs directly out of the wall?

I haven't been able to find a detail "step by step" method for running a fridge compressor as a vacuum bag pump.... how easy is it?

I think I may have found a better source for Divincell foam. I'm guessing its far more suitable than PVC right?

Cheers, Will

A fridge pump runs from AC so a Google search for "cheap little sucker"

This will return all you need to know.

Time for an update:

I have the fridge compressor all set up and ready.

I'll be buying the glass/resin/vacuum material/release film later this week.

As for the core, I'm thinking of switching to paulownia, simply based on cost and strength.

Now I'm searching for any info related to making fins. I think it should be a relatively simple process, once a mold is produced. Anyone know of any relevant sites describing the process? Perhaps there are some alternative suggestions....

Cheers, Will
