If you are buying the core only with the intentions of making your own panels then you can use what ever resin system you find the cheapest ! so apart from the resin the choice of glass fabrics would be next !!
There is more than one core!! they come in any variations so check carefully the type and what it is !! (low density 1/2'' thick H-45 divinicell ) but there is no description as to what it really is !! get a sample to be sure its what you are wanting ! if it sheet foam make sure you get perforated ! has lot bleed holes to let the resin come up or down and lets the air out from underneath !!! How do you intend to stick the core to the glass ??
You would also need a nice shiny table top to mould on ! not forgetting gel coat to be sprayed on to lay your glass onto and get a nice finish . You can cut the core to the shape and size required and make each panel and have very little waste !

Now think about how you intend to make and all the work involved !the core is just a part of the whole thing ! ADD to that resin glass and gel coat, mould release wax ,and a ,shiny or patterned melamine board to mould the sheets on top of plus buckets ,rollers masking tape etc etc
To even come close to getting a quality jobthe gel coat would need to be spayed ,and the core would definitely need to be vacuum bagged onto the glass surface !
Suddenly are any of those premade panels really that expensive ?? remember there will have a manufactures guarantee of quality and consistency!.

Reminder the floor you would need a better core than H45 !! 3/4 x H65 would be the absolute minimum density ! H80 Is much better for walking surfaces !!, the glass layup is important, so top surface gel coat and 1708 then 3/4 core thickness core !! over that 1708 + a unidirectional running across the panel NOT length ways !!

We buy the bare core for that price. I can figure out what it would could to lay them up if you want.

It doesn't cost a manufacturer $200 per panel to laminate them. I can laminate 8 panels in a day plus materials and with my lack of experience (doing it slow) it still would not cost $200 per panel to laminate. I'm sure the manufacturer all set up can do it for far less.

You just want 8 panels (4X8) of high density foam with a layer of 1208 and peel ply on each side correct?

Was thinking more like plascore or nidacore (honeycomb). Nida showing it with 2 layers of 18 OZ. Using it for non-structural bulheads and cabinets. Want to put this back together with zero wood.

Okay,

I will have the guys put some numbers together for me tomorrow. I know that he has some inexpensive resin that could be used for what you are doing.

Like I pointed out before do you actually require 8 8x4 panels ?? or are most of the panels smaller ?? why not manufacture panels to the shape and size required !!
CAN SAVE A LOT OF MATERIALS AND THAT MAKES IT EVEN CHEAPER !!

what is it ????

A buddy of mine had the same problem with termites they didn't stop at bulk heads and paneling they ate out the stringers too

Termites on the inside eating the framing etc and polyester mites on the outside seems its a loosing game !!

Again.. Carbon-core for around $180 laminated. Shipping was $120 to middle GA for 6 sheets.

**tunnels** · 08-28-2017, 09:09 AM

so what was the final choice of materials ?? what was the final outcome ??

Job has been cancelled..... he had the boat tented and it slipped off the lift and sunk. The exterminator wanted the boat in the water so he let the boat down into the water and left it in the lift. Boat drifted back a little, tide went down, lift held the front of the boat up and the transom deep sixed.
