FX-1 Widening Rails

[LimitedSlip7]

I need to do a few repairs to the bond line rails on a carbon FX1 hull I picked up and am planning on widening the rails ~3/4" per side. What would be the best way to go about doing this? Should I try to find some CF strips or make some kind of mold on the side of the ski?

Right now I'm planning on making a foam mold along the side of the ski then laying the CF over the top of the mold and current rail, then removing the foam and reinforcing the bottom of the rail with another layer of CF. This is the first time I have done this so any advice would be helpful...

I think blowsion or wamiltons has a kit to widen the rails. Its basically some denser underpad applied to the outside of the rails and then you turf over the existing rail and new padding. My buddy has them on his superjet and I have something like it on my XFT. It makes for quite a stable ski, if that is what you are after. It ends up being about double the width of the current rail.

I actually need to recreate the rail as it was poorly trimmed.

^^^^ This...


I think this is the best thing you can do to a FX1. Keep us updated on your progress.

Thanks, that is exactly what I was thinking about doing. Guess I'll give it a shot...

I did a similar job like ScottS - here is where I tackle it in my build:

I have the hull in paint stage now - but the bondrails are very strong! I did 2 1708 on top, 3 1208 on bottom. This combination makes it near bomb proof (and probably added a few unneeded lbs) - you could get away with 2 1208 on bottom no problem - even most likely with all 1208.

Not like this,

I'm wondering wether I should attempt to use CF for the rails or duplicate Scotts efforts. I would probably just use 4" or 6" wide 5.7oz bidirection CF tape. Any recommendations? Best epoxy to use?
