Super Jet another refoam project

[Cliff]

went to tearing the old dingy looking turf off my ski and found this. any help, ideas, or suggestions would be greatly appreciated. i now know why my ski leaned to the left.

 

[BruceSki]

wow that ski was poorly prepped for glasswork. cut it all out and go with a non water absorbent foam and add drains. make sure to sand well and remove paint for the glass to adhere this time around. Acetone on the surface before you lay the glass.

 

[Cliff]

where is a good place to get the foam?

 

[BruceSki]

home depot. cut it up by hand. Here is a link to mine that I did last winter.

thanks, ive been looking for a good thread with plenty of pics. this will be my first go at a refoam plus i want to move the footholds foward a little.

 

[BruceSki]

you may have to lower the exhaust tube if you move the footholds too far forward.

 

[Cliff]

theyre all the way back now. surely they will move some. if not, i will give the exhaust tube a courtesy clearance lick.

Didya find any pecans in there?

really though, you have to cut them out & grind all that mess off the hull and footholds before you relay glass. it does not even look like epoxy.

Use boat dock foam. You can find it used and the boat store just gave me a huge block. Cut the exterior off about 2 or 3 inches deep and the foam should be like brand new. Just use a hand saw to cut and a sander to form if you need too. That stuff takes load very well too.

making a little progess. my buddy roundman has no problems cutting on my ski

 

[D-Roc]

how heavy is all that foam? lol. you doing a scupper of some sort while your in there?

 

[Cliff]

my ski was pretty soaked inside there. i should have gotten a before and after weight. it feels much lighter now. i have a duckbill already that does just fine so ill probally skip out on the scupper. definately going to install a trim tube whether i ever use it or not. still havent decided for sure how im going back together with it.

 

[D-Roc]

yeah that foam has got to add upto 30lbs on some skis. i ripped my garbage bag when i picked it up. keep on keepin on.

Here's the stuff I used http://www.uscomposites.com/foam.html
Good have fun with your winter project.

thats the normal stuff people use, I was at Comp Canada a few weeks ago and noticed they had polystyrene 2 part foam. i would use that if i was pouring in foam, that other stuff will be waterlogged in a season.

Really, I foamed my ski in 2007, it is not waterlogged yet. When I got it, I refoamed it, I wasted my time. Wamilton had prepped the hull in January 2001. Everything was still dry in 2007. They get waterlogged when the hull is not sealed up properly. I have had my fair share of not sealed up properly hulls. It can be done.

You have to put it in the water every now and then before it gets waterlogged.
