I just picked up my shipment of Stru-cell. At first glance looks as advertised, not crumbly and bendy. Local supplier ordered it for me, $50 sheet for 3/8 and $75 for 5/8. Less than truckload shipping was harsh, 20 something sheets in a 4x8 foot box about 1 foot high. $350 Florida to Central Texas. I'll report more once I start laminating. Dinghy calls for vinylester with 400 gram meter skins on 3/8 inch core.

Subject: [harryproa] Air Cell Vinylester Foam Core

 

I received a box of product sample from Poly-U-Mac yesterday. Included was a selection of Air Cell http://www.polyumac.com/aircell/

Ive attached a pdf of Poly-U-Macs product line, it has charts showing the specs of both the air cell and store cell.

So we have a Vinylester Foam Core and a PVC foam core, can anyone help educate me on the differences- pros/cons of each as a core material?

Also included were samples of their Gator Board, which after doing some reading deep in the "archives" of this group seems like it could be useful for localized reinforcement of areas under cleats, winches, etc. Not sure if it is worth the cost as I haven't checked into that.

The company was hesitant to give me any prices until after I received my samples, not sure what thats about really - but I will be looking into this, hopefully the prices will be as reported earlier.  This would really bring the IF construction technique into our price range in a reasonable amount of time. I keep making myself continue to research and price out the older strip building techniques of Harry - we run a custom woodshop with access to cheap materials from our sawyer. Obviously lots of tradeoffs here as far as time and complexity of construction. (Not looking to get offtrack on the foam vs strip building as it has been discussed in the past) Our lifestyle and living situation (large metal building, including our shop) along with being very comfortable making curved objects in wood just make the strip building method an attractive one to us. (Time/vs $) for us.

Fingers crossed for the foam core, we do enough work with epoxy/wood construction to know the reality of it.

I have a lead on a local university to run the series of tests, that rob emailed me (off the list), on the different core material! s. Will let you guys know how that goes.
