Blaster B1 rocker nose!!!

[Dirty Jersey!]

.......i was looking to rocker a extra b1 hull i have but i want to do it from scratch, anyone have any ideas on how to go about doing this or have pics of any b1's that had rockers builts from scratch???? i would like some advice cuz honestly i have no idea where to start, i know how to glass but just need a idea on where to start to make a mold:brap:

I started by looking at the ski from the side and tracing along where I thought I wanted the rocker to start and curve up.
Then I took expanding foam (would probably try different foam next time) and poured it inside the nose section, flipped the hull over and started grinding along the lines I had drawn. I dont know if there is a "right" way to do it, but there are a few rocker threads (mostly stand up) that will give a good general idea of how to tie in the new shape with the hull etc.

Good luck!

thanks!, i seen a thred a while ago on someone that used expanding foam but i have looked everywhere and cant seem to fine it, now did you draw your lines and cut it than fill it? and also did you put like a piece of wood or anything inside the hull when you filled it that way it doesnt just go everywhere?

I tipped the hull on its nose and poured the foam in, shouldn't need wood or anything, maybe build a few dams out of cardboard if you need to. i did a few pours to make sure it filled in properly. I drew the lines, checked to see where it tied in. I also removed the bed plat for the tank because I wasn't sure how far back the tie in would go. i think on my next build I will leave the tank plate in and work around it, i ended up putting the tank right back where it went, minus the huge plate.

With a username like dirty jersey you should know how to do it

A friend of mine just rockered his SN and he simply made a cut on the sides, trimmed away some excess on the nose and put a piece of allthread from the top to bottom. Each day he heated the hull and cranked down on a bolt with a brace on the bottom. Next day he took it in a little more, a little more, until he got the shape he wanted, and then he shaped it on the sides and glassed it back together. That's my plan of attack, but I have not done it on a blaster, so we'll see.

I cut the nose off my B1 then I put a cardboard base setback in the nose, tipped it upside down and poured 2 part foam in the nose then I shaped the foam with a long sheet of grinder paper wrapped around a piece of stiff packing foam (hard to explain). Once I got the shape I wanted I laid down 2 layers of glass and let it dry. Then I flipped it over and removed the cardboard and foam then tied my new shape in with more layers of glass. I was itchy for weeks and my garage is still covered in dust but I'm already wanting to cut up another B1 hull and redesign the whole bottom deck a lot more

i understand what your saying, i mean i have the whole idea laid out in my head now i just gotta do it, so im guessing it is a lot cheaper to do it your self if you have the time?

 

[zimmy]

I bought about 450 in materials which turned out to be waaaaayyy too much, but hey, at least I have stock left over to start my next build!

Its cheaper to do it yourself, as it is with most ski work. And yes, its just one of those thinsg that you just have to get out and do it. If you dont go at it like a hack you should be ok. You can always fix a mistake, so keep the parts you cut off incase you need to use them again.

Keep us posted.

Thanks nizzit, whats stroger and more reliable the glass mat or the cloth....from my past experience the cloth held up better but will the mat bond better is you use the right products

 

[964Chris]

biax is the way to go http://www.uscomposites.com/specialty.html

 

[Dirty Jersey!]

does it matter witch biax i go with or are they all the same, and what is a good foam to use that us easy to shape and work with...Thanks!

1708 biax without mat is real nice to work with and contour to different shapes. I also used chop mat inside to strengthen everything up.

 

[Dirty Jersey!]

thanks all you guys are a big help, so my plan is to cloth the outside than on the inside use matt than just a layer or 2 of cloth to make sure it is bonded well and is strong enough.....sound like a good plan???:Banane36:
