Seeking input from those in the know.
I am looking to make a 2 piece boom for my Duotone Slick Wings.
Has anyone tried making one?
How did it go?
Any tips or pitfalls to avoid?
I am thinking of buying the end pieces, some 25 mm carbon tube and 20 mm carbon tube, push button clips and fishing rod grip shrink tube and having a go.
Intended so I may pack the boom with the wings when flying.

Buy a adjustable carbon sup paddle handle and chop it?

Last weekend I was flying from Hawaii with Duotone Platinum boom. Very light. Easy to carry. No problem in a plane.

Yep. put a video up last year I'll look for it.
bottom line, it flexes marginally. Enough for me to not use it lol ??

Very keen to see it

this is how DT's Klaas Voget handles the boom matter - it's a standard Fanatic adjustable paddle he uses !

I used the new boom yesterday
felt like a normal boom. No movement at the join. Very happy with it.
Making another - just because I can - from bits from Amazon and the end bits from Duotone spares.
Will post the results

Just curious how much it weighs. Any idea?

Platinum boom 367 grams
two piece platinum boom 427 grams
made from bits from Amazon 408 grams before putting grip on it

I guess if you have the need for a 2-piece, then the extra weight is OK. 1 meter of the fishing pole heat shrink grip weighs about 65 grams, so it's a pretty significant part of the total weight budget.

For strength, I would be tempted to make the back of a 2-piece boom a bit shorter than the front so that the joint is as far as possible from the part that you are holding. Probably doesn't matter...

I made 4 booms from ice hockey sticks for myself, two long ones for my 5.0 and two short ones for my 3.5. The bare hockey stick without added grip is great in the winter, but it does get a little bit more slippery if you get it wet in the summer. The cost of making these is pretty hard to beat because the carbon sticks were salvaged from dumpsters at an ice hockey rink nearby. I wanted a lighter boom that is also warmer to hold than the standard aluminum boom.

The windsurf boom grip material I use is really thin and light,.nothing like fishing pole heat shrink grip. My booms come in at ~ 280 grams before the boom grip and ~ 309 grams after adding it (grip and contact cement). I really like the thin grip. Just enough to eliminate the slippery feel of the carbon tube. 26mm final diameter

I was commenting on the 2-piece boom where it was clearly used. My first home made boom had a cork mat grip and it was nice to hold and warm, but not very durable. The heat shrink grip is rather dense, so while it gives you good grip, it doesn't do much in terms of thermal insulation and it weighs a lot even though it's not all that thick. Ease of application and replacement (although I have yet to see any actual damage on my booms) is also definitely a bonus. And it's pretty cheap too.

A good windsurfing boom grip foam will be lighter and feel warmer.
