: hello all,

: I don't mean to start the war again 8-) , but I got some real questions: how
: deep does the epoxy being absorbed into the wood ? I'm talking about the
: 4mm marine plywood that pygmy sells with it's kits.

: my thought was that the epoxy is NOT being absorbed very deep into the wood,
: thus creating a structural strength: epoxy on the outside & wood on
: the inside. so when I built my coho I let the wood absorb & absorb.
: what I got is a tank ! It's strong & heavy like hell. I tend to
: preffer strength over light weight because I know I'll need the strength
: sooner or sooner.

: after a while I started to suspect that the epoxy is being absorbed well into
: the middle layer, & therefore is completely "filled" with
: epoxy when wetted on both sides. I'm sure that a fully epoxy wetted wood
: is stronger than the structural theory I just mentioned, but I'm not sure
: which of these 2 options are better for me. again, this is just MY
: preference & I don't want to start a war here.

: an advantage of the heavy version is less rot. well, I think that epoxied
: wood doesn't rot, & sealed wood might or might not rot.

: so.... does anybody really knows how deep into the wood the epoxy is absorbed
: ?

: I was thinking, as an improvement for my next boat, not to wet the wood
: before glassing it, but I realise it's not smart since the wood will take
: the epoxy from the glass. It's better to just squeegee the epoxy over the
: wood before it's absorbed.

: am I correct about it ?

: one last question: any web links to system three ?

: I just used what I got from pygmy, but it's time to see what else is
: available. any info appreciated.

Hi Rehzzz :)

My guess on the depth of penetration would be that the epoxy would only soak in through the outside layer, ad it probably won't go through the glue layer in between the wood layer. ??? And on some woods, it may just be thousandths as the grain could be an open one or a closed one. On the Moh. ply, I would think it would soak into the entire outer layer of each side, but probably not into the middle layer. Just a guess here, as I have never used the epoxy.
