Chopping a sqaure

[Jkins30]

Any tips or pointers on chopping a sn in the back? Want it angled. To be honest, I don’t know where to start. And what’s y’all opinions on scupper vs bilge

i run both scupper and a bilge. cause you never know.

If you look at my thread I chop my square 2" tapered just like you said. I ran Duct Tape across the gap to get the basic shape, check the pictures for the basic technique I did. If you have any questions feel free to ask.

About the scupper, Im debating the same thing right now. I flip back and froth between two Rule bilges and a stock bilge and two rule bilges and a 2" ball scupper. Im just afraid of sinking my ski so I still have not cut hole for the tube yet.

Is there a real advantage to one over the other? Bilge and scupper? I’ve really got it stripped down at this point. Figured now is the time to go all out. Just don’t wanna be kickin myself a year later, wishing I had done something I decided not to. Y’all are quite knowledgeable, so I appreciate the help/info.

This is one of those questions that half of the community will say Scupper the other half will say no Scupper. There have been enough incidents where people have gotten separated from their skis and they have sunk due to it acting as an air vent when upside down to at least educate yourself on it.

They bail water incredibly fast and work incredibly well when you're moving. They have been known to sink skis when they are docked or when the ski is upside down.

The other methods get water out slower but don't act as a big air vent when the poop hits the fan.

There are serious pros and cons to both, partially why I have yet to commit one way or the other on my build.

Man, I’ve been deep in your build. Insane work!
I’ve basically stripped my hull and chopped the front of it off. I don’t know too much about fiberglass, so, I’m kind of hesitant to order online.

Talk to US Composites on the phone. Tell him that you are reinforcing a stand up jet ski and he will walk you through the ordering process and get you going with everything you need. For a normal reinforce I think he recommends 5 yards of 1708 and a gallon of resin if you are not using much cabosil, two gallons if you are doing a bunch of filling or fairing. Also you got dispenser pumps, cups, mixer sticks, dye, cloth and rollers etc. Im on my third gallon of resin at this point but I have been wasteful and I am doing a lot of glassing on my build.

Try to be honest with yourself on how much resin you think you are going to use, the pricing scales pretty favorably with larger orders of resin from US composites, if you are going to use 3 gallons anyways order it now so you get the third gallon for a significant discount. I wish I had done this.

1708 in my opinion is great but I also think you should have a small amount of 17 oz biax on hand. Its like 1708 in every way except it does not have the chopped strand backer. It is much easier to lay over contours and more importantly the threads can shift over angles allowing for much better drapability.

Watch boatworks today on youtube. I dont know why but I think his videos taught me the most. He has a pleasant way of explaining the process and works with 1708 a lot.

I'm glad the 17 without the backer ended up working well for you
I'm surprised not many use it.

Thanks for all the detailed info. I will give them a call tomorrow. Sounding like it may be pricey . I’ll check out the YouTube channel. Thought about maybe starting a build thread. Then after spending an hour or 2 on yours... shoot don’t know if I can live up to that
