Huh, yeah mine definetly didnt have that in it. I sent you the pics of my tank. hope they are helpfull. Good luck with the rest of your build. Looks like its coming along nicely.

Morning guys just a quick opinion/question. I am getting ready to wet lay the material on the inside of the hull and wondering what order of fabric to do.
My original idea was laying a layer of 17 oz biax then 3 layers of twill carbon then another layer or two of 17 oz biax. My question is do you think it would be more beneficial to alternate the layers biax, cabon, biax etc. or does it matter. Also any opinions on how many layers you would consider being an adequate amount for hull nose. Thanks

IMO since your using biax, no it wont matter, just use carbon as your last layers.
When i do a ski nose/tight bends I use many layer of lighter oz glass, its a lot easier to work with and you don't fight air bubbles as bad.

I don't know I always seen the fiberglass as the core when laying carbon fiber. I would measure the thickness of the old lay up you cut out. Use a micrometer and then plan your lay up to get about the same thickness. Whoever supplied the materials should be able to give you a thickness like ".015" for example.
Carbon fiber is good for directional loads. I would cut your reinforcement at different angles to take advantage of it's properties. One at 0 degrees and the next at 45 degrees across the weave. Lay up would be something like this:
Carbon 0°
Carbon 45°
17oz Biaxial
17oz Biaxial
Carbon 45°
Carbon 0°
When wet laying that i'd wait until each layer starts to gel before laying the next. Laying it all at once may cause warping or air pockets that are difficult to get out. What weight is the twill? That biaxial may be difficult with tight bends.
Oh and after playing around with my ROK I noticed I do have a 4"x2" block in the front. There was aluminum plate glassed in and it feels like foam. That's for bolting down hooks for the waterbox's rubber straps. I been playing around with moving my waterbox, changing some stuff here and there because I popped the old kart tank pod out and going to have a aluminum gas tank welded up. I have 550 tank now that holds 4 gallons, but im shooting for 6. Hopefully I wont need to carry a spare gas tank in the tray anymore.

Thanks for the input guys, I am not exactly sure what I will do yet but you have given me some good ideas going foreward. I am hoping to start tonight so I will keep you informed on what I do and post some pics.
"What weight is the twill? That biaxial may be difficult with tight bends."
I am not sure of the weight but it is a little heavier carbon, it was the only type they had at our local shop. The biaxial fabric I have notched out some of the edges to help it bend easier, so hopefully it won't cause me tons of grief but I will probably be babysitting it for a few hours lol.
"I have 550 tank now that holds 4 gallons, but im shooting for 6. Hopefully I wont need to carry a spare gas tank in the tray anymore."
Damn Curb a 6 gallon gas tank lol are you trying to go cross country with that thing. For right now I am planning to run a cart tank till I get the dimentions to build a custom 4 gallon tank. I cut that 4"x2" lock off, and if freed up a ton more room maybe even enough for a 6 gallon tank
.
I will post pics as soon as I can.

Well the 550 tank I have makes about the most of the room available. The waterbox could be set forward more and there is 2" I could raise the tank. Just raising it alone counts for a little more than a gallon.

I sent this to you like you asked in a PM but never got a response? I figured i could post in in here too for people doing a search at a later date for a ROK gas tank. this was my tank and it held somewhere between 4.5-5 gallons
I reposted the pics down below.

I can't view the first few images. I'd like to see what you did. Im having a tank like that made up soon.

Are they not showing up?

I can't see them either and we went with 17oz and a latervof carbon next. And now its curing in my living room plan on doing another biax then carbon probably 2 more times like this and I think that should be good

Hopefully they can be seen now.
here is the rail so far guys, used blue foam insulation to make the template and it worked pretty well. Waiting on last layer of biax to dry so I can cut it.

Looks great. What was your lay up?
I've been working on mine as well. I reinforced the handlepole mount since there was tons of flex and gelcoat cracking. I hot glued cardboard inside to bridge the base of the mount to the outer edges of the hull (I kept a relatively flat surface to put a larger backing plate to disperse load). I laid 6.7oz 2x2 twill to strengthen the make shift mold, then 17oz biaxial and filled with 2 part foam.

Nice, I ended up on the bottom of the hull and bottom sides using 2 layers 17 oz biax 2 layers 2x2 twill carbon, then another 17 oz biax layer. For the top i ended up doing it in with 1 layer biax, 3 layers carbon then another layer of biax. I will take a pic when I flip the ski again. I think the pole bracket should have enough strength to hold up but we will see. After laying the biax I had a hard time keeping the air bubbles out so I ended up letting it cure then afterwards I used a syringe to inject epoxy into the air pockets; seemed to work great. The rail I just used blue insulation sheet foam cut it to the width I wanted and adhesive sprayed it to the front of the hull. then did 1 layer carbon and 2 layers biax and it worked out nice.

lol@doing glass work in the living room... haha
Nice work BTW.

yup it was to cold here to do it outside and cure daily so we did it inside now its back out to the garage and getting sanded on as we speak getting ready for paint
yeah it is for a couple tabs that help hold the front of the hood on since there are not any hooks.
