300/440/550 Another 300sx build thread

[MikeyB]

Roughed in one layer of 8oz cloth and about a layer and a half of chop mat on the bottom.

 

[caseynz]

you going to put tubbies on it?.

 

[Abbott]

Do you know how much a stock 300 hull weighs?? not that it matters just curious on how much overall weight is added to the hull after its all finished

 

[MikeyB]

Yep its getting tubbies, we are going to try shaping some out of foam. I think the hull is around 60lbs? Then I would think at least 20lbs in material added to it by the time its done

 

[MikeyB]

Set the motor and pipe in to see how much room there is, we are thinking about making a battery tray in the corner by the bulkhead

 

[MikeyB]

Craig (CTKawa) just placed what we hope to be the final order of materials to finish his hull aside from paint and turf. Next on the list is to power-wash the engine bay (should have did this first), re-foam the tray and then finish the glassing/body work.

 

[MikeyB]

Laid some mat down on the foam up front and tried out a piece of peel-ply over it to see what thats all about.

 

[PowersportComposites]

Sub'd. Very cool I'll be lurking. Plan this as my next build.
What's the purpose of the peel ply over the foam?

 

[MikeyB]

The peel ply goes over the fiberglass. I was pretty surprised with how well it works, it leaves the surface a lot smoother. You put it down after your lay-up and then pull it off after the resin is dry.

i have reinforced up to were my finger is in the 2nd photo just not above that. that was done on flat water too!.

 

[CTKawa]

Yeah we plan on reinforcing pretty much every inch of the ski. Should be pretty solid thanks for the heads up. Sorry to hear about the crack.

Mine broke there too. I just got done adding a layer of carbon to the inside edge of the hood seal lip before I bought into molds to start producing a brand new hull. Anybody interested in a fully reinforced 300?

Whats that white stuff ? I see a bucket of joint compound in the backround.

Roughed in the nose a little bit, still a bunch of sanding and shaping to do there.

 

[MikeyB]

Lol thats what it was, we were searching for a cost effective filler to smooth out the foam since anything polyester based would eat it away. This is a first working with these materials so there is a bit of a learning curve. I eventually peeled it all off for epoxy based fillers, see post #61. Aren't you bugging me about this over on pwc also? Thanks for being so helpful.

 

[WB1994]

Well you said you werent going to post anymore over on PWCtoday's thread because we pointed this out ..... was wondering what would happen over here .....

That had nothing to do with me not posting over there anymore, I gave up and come over here after it was getting hacked everyday..either way we'll stick to epoxy based products..

 

[skibum]

it's all epoxy now, the nose looked great last time I was over there.
