The "why the hell is he doing this" build

[So Low Roller]

this is nuts

Good time to do a build and more then enough motivation. How do you plan on bringing the top deck down? Do you have a final weight in mind or just rock whatever you end up with?

 

[HolyDiver]

@iangdesign you a are right got plenty of motivation!! As for the top deck I just took a sawzall down the top of bond line and cut it off. Then measured 2in around the entire top deck and then cut that. I have no idea if that's the way you do it but that's the way I'm screwing it up.

Also by cutting the top deck in the front it actually moved the entire top deck forward 2in as well. I still think I'm gonna rework the pole bracket area and move it a little forward. I don't know what I'm doing so guidance is much appreciated.

Well this is what I have before the heat and fiberglass dust got to me.

Nice. In for this.

OOOOO .....YES HE DID CUT THAT TOP DECK OFF . I like the cut of your jib mister ! it takes me days to decide what direction i want go only to change my mind and go another.

Make sure your ebox,tank ,pipe etc will fit under the top deck before you make your hack. Moving the top deck forward makes more room for the pipe and tank but there is a limit . On a SJ with a B pipe you have about 3 inches MAX if you keep the same mounting points.

Dismissed .... Resume Hacking

Yep yep I have no idea if any things gonna fit but once you start cutting its hard to stop. If I threw a 650 back in it I know everything would fit I looked at my other one and have a ton of room. I think I'm gonna end up trying to make a water box and most likely get a kart tank.

Move the pole mount as far toward the nose as you can! Glad you hacked it down a couple inches...looks cleaner lower. The top deck compliments the rocker very nicely.

Well nothing got done tonight I had to go look at wedding venues. Yeah it was a total blast the only thing I could think about was how to rework my pole bracket area. That's when you know you have a problem.

Is there some local store like Home Depot or something to get two part foam? Or do you guys have a link where I can get some cheap?

Something like this a good deal?

I think I have some left over to form my pole area but not enough for everything else.

Looks like a good deal. Think I paid round 20 for a quart kit

the under water planet Cybertron

Has the 80s and Michael Bay been lying to me? Cybertron is underwater?

 

[VXSXH20]

that is a fair price, about average i paid 65 or so shipped for my 4lb foam system

haha ian ! ^^

 

[HolyDiver]

Ordered my foam today and made a little progress yesterday.

I need to know what kind of foam board is easy to work with for when I build my tubbies.

Will this work ?

XPS works well. You can hot wire cut it and it sands easy. You can also bend it using a heat gun to a certain degree.

Edit: just saw the link. Yes that will work, but you probably want something thicker than half inch. I used the Owen cornings XPS from home depot. They sell it in 2'x2'x1". I cut and glued them to 48"x6"x2" to form the blanks for my Tubbies. Make sure you use an adhesive that will not dissolve the foam. I would recommend gorilla glue.

I would pick a heavy biax or triax fabric without mat backing. You make great points on the mat absorbing the surface anomalies and that its very thick which does allow for easy buildup of a very stiff laminate with good strength characteristics.

If the purpose of the build is to increase the ski's potential to it's maximum, why not take the time to add the couple extra layers of plain biax required to reach the same thickness. The result would be equally if not more stiff, far stronger, and marginally lighter.

Not that its a terrible choice...there's just better choices out there for not much more effort is all I'm saying.

Just an example:
http://fgci.com/bp_viewproduct.aspx?itemnum=125634&oldItem=125634
Added bonus is the fabric should not really be any stiffer than an equivalent weight woven cloth. Everyone thinks biax is stiff and unconformable because they have mat stitched to the back of it.

Dalt, what would you recommend for reinforcing and redoing a tray for strength and weight savings? S-glass?

 

[HolyDiver]

Damn it is 1/2 in i never saw the decimal. I'll run out to Home Depot today and see what I can get.

@Nate_D do you have any pics on how you did yours?

Yeah I used a combination of s glass and triaxial to build the tray on my top deck. This glass is fantastic. http://thayercraft.com/9773.htm Very strong and being 8-Harness very conformable for it's weight. After having used up 30 yards of their 21.85oz I have no doubt about thayercraft's bullet proof claims.

It's pretty slick how you were able to just flip around the gas filler and pole mount! Keep up the good work man.

I did a fairly detailed write up on page 6 of my build thread. There's more pictures than probably needed. I made mine to be plugs to pull a mold off of, but the first steps in forming the Tubbies are still applicable.

I didn't realize that was your build i read the entire thing about a month ago and that's what kinda inspired me to do mine!! There can never be enough pics on a build thread. Your trying to show everyone step by step how your doing it. The more pics the better I think.

Should have my order from us composites today so will see what I can get done tonight.

 

[HolyDiver]

Well got my stuff today and I think things are gonna slow up some. Now comes the time consuming stuff.

Also tubbies are a lot more difficult then I expected. I've got some rough shape ones made up but I'm not sure how tall I want them and idk how far from the bottom deck I should start them. What do you think?
