tiller extensions, carbon fiber, golf etc...

I have a student who wants to make a telescoping golf club. Having never golfed I showed him the Arriba tiller extension from my H-21.

Does anybody know where I could get some lengths of carbon fiber tube similar to the tiller extension material? Does anybody have a number or link to Arriba? Does anybody have any suggestions at all?

I have some budget for project materials but I can't find anything other than extremely small diameter carbon tubes.

I've never done any business with these guys, but it looks like they have a pretty good selection of stock carbon fiber tubing sizes:
MacLean Quality Composites http://www.macqc.com/

That looks like a good place to start. I'll give them a call. Thanks

Mike Krantz with Sailmax.biz has an inside line on those hot sticks (carbon, glass, or combo) and knows the guy that builds them (they are built on a custom mold). I would suggest giving Mike a call or email...contact info should be at http://www.sailmax.biz

and everyone that currently uses the fiberglass hotstick should really get the CF one. You'll never look back, they are simply awesome.

Marstrom (http://www.marstrom.com/) makes a small diameter (3/4") telescopic tiller. Part #610, 205 EURO plus shipping. I don't think it is strong enough to use as a golf club shaft.

At the diameter required for golf club shafts, carbon tube will be too "weak" and too flexible, whether made either in filament wound or moulded. The only thing that I could think of for that application that MAY work would be "graphite" fishing rod blanks, very very expensive though, but with light weight, strength, and the right rigidity comes cost.

I'd look at www.GolfSmith.com and look in their clubemaking section and search on "carbon shafts" They have them in both 0.335" and 0.370" tip diamaters and 0.575", 0.600" and 0.605" butt diamaters. I'm thinking with one of each cut in the right places you could make them "nest" together. I'm guessing that your student is attempting to make a club similar to the Divinick, http://www.divnickgolf.com/telescopic/index.html.

I would think that by using existing carbon shafts from almost any application, golf or otherwise, the finished product would not have any desireable "feel" to it as the flex, kickpoint and general frequency of the shaft.

Just my thoughts,
