Duotone Slick

[winged surfer]

585 gr (alu) Vs 330 gr (carbon).
That’s what is written on the website.

Here's a good look at the Slick with the aluminium boom.

Light wind with the Slick.

For those interested here's a review of the big Slick and comparison with the Echo by Dominic Hoskyns.

I converted a Duotone Slick Aluminum boom to carbon for TJ at Big Winds using a shaft from Black Project--a very pretty shaft, it killed me to cut it, silvered carbon fiber. It took about fifteen minutes to do the conversion--maybe less. The end result is super light. If I get a slick that will be the first thing I do.

The Ke Nalu Xtuff handle came out at 220 grams and worked and fit great.
The shrink wrap was a extra 100 grams that really only seems to have added a little visual benefit

Hey Bill - what was the OD on the boom, and what wall thickness did you go with? Waiting on delivery, figure I will get materials now to expedite carbon swap.

Thanks

I didn't measure it, but there's another at my shop, as well as the offcut. I'll try to remember to do so this morning. Of course, it's whatever Black Project uses for their shafts, but simple enough to measure. I had to cut a little notch in the inner sleeve of the small end cap. The outer sleeve fit loosely but the inner sleeve was too tight to reliably insert. A little wedge, a generous amount of hot glue, and a mallet solved the problem nicely, and the part is in compression anyway.

Looks like their standard diameter shaft is 29mm, and reduced diameter is 26.5. However, at this rate I probably won't get my wing until September... so maybe I should just wait until I see the whites of its eyes.

Finished my slick carbon boom, 233gms. Used a kayak carbon paddle shaft bought off ebay, 130cm long, US$66. Fully sealed, no rivets.
Just need some wind to try it.

nice job! hard to tell from pic did you use the plastic end parts from the Duotone Al boom or make those yourself?

[Wingfoil2001]

I used PVC foam blocks bonded to the shaft then shaped and lightly glassed in carbon.
I thought of taking moulds off the Duotone parts but too much work for one item.
No grip on the shaft, just rough sanded with 80 grit. I’ve used this method on my carbon kite bars for a few years and it works well, just don’t get sunscreen on it.

Nice work. I guess you could sell that aluminum one. I've just drilled the rivets out, pulled the end bits off, then hot glued them in place on the carbon shaft and added rivets to keep the bits from turning.
