Mike, I know Ti Goat has 0.45 and 0.6 diameter poles, not sure if that's internal or external diameter. Probably could just email and ask. And, they should be able to cut it to whatever length you need.

Be sure a CF jack has reinforcement around the circumference of the insertion end.

A simple tube cut to length will be a risky bet unless it was wrapped to handle that stress.

I have brass tube that is now oval from supporting a DuoMid.

YMMV

Ti Tube Instead? on 07/26/2011 02:05:40 MDT Print View

Probably more than you wanted to pay but certainly bullet proof and light (I get 44 grams at 10" length).

Greg- wouldn't have thought of that- thanks

Chris- that would be the bulletproof solution for sure, but definitely too spendy

Josh- I'll shoot tigoat a email and see if they can come up w/ something

DragonPlate seems to have some interesting products. Wouldn't it be neat if you could walk into Home Depot and buy those things over the counter?

Must be substantially thinner walled since its density is 91% greater than that of titanium.

I "eyeballed" the wall at 1/32 +/-

And I can assure you it has been tested several times, and passed.

Hey man, don't get me wrong whatever gets the job done and is light I'm good with! As much as I love cuben, titanium, and carbon fiber not everything has to be high-tech to be good.

Aluminum tubing on 07/26/2011 17:01:42 MDT Print View

A 0.625" Aluminum tube with .035" wall would be around 33 grams but is expensive here (2024 T3 is $14+/ft):
http://www.onlinemetals.com/merchant.cfm?pid=12799&step=4&showunits=inches&id=946&top_cat=60
0.049" wall 6061 T6 is a lot cheaper $4,83.ft.
much cheaper but in 6' lengths is available from http://texastowers.com/aluminum_.htm

If you can find an old TV antenna, you might be able to scavenge what you need.

CF Golf Club Shaft? on 07/26/2011 17:06:03 MDT Print View

Any thoughts on how it would hold up to the applied load? I'm betting they are wound with good hoop strength. I know folks are able to find these pretty cheaply though I've never looked myself.

Cheap possible Pole Jack on 07/26/2011 18:21:36 MDT Print View

I just measured + weighed a piece of tubing from a swiffer sweeper handle at:

Weight = 1.3 oz (that includes a little plastic clip you would want to remove)
Length = just under 12"
Top ID = 5/8"
Bottom ID = almost 3/4"

It is probably lower-grade aluminum but at this diameter + length it would take a lot of force to bend it. The top is slightly narrower to fit inside the wider bottom portion of another pole (like a tent pole).

Even if these specs don't quite match what you want, it might be worth going to a Target or Bed, Bath & Beyond and seeing if anything is the right diameter.

aluminum on 07/26/2011 18:53:23 MDT Print View

I might peruse my Ace Hardware- they sell aluminum tube (and brass) stock- I used some of the smaller stuff when I made my ul grill, think I remember seeing some larger stock

CF golf club shaft might work as well, don't think I'll have much luck sourcing one here though

looked on ebay @ CF it's kind of pricey and not sure of the quality/strength either

that would have been great- the diameter is just about spot on, but about 1/2 the length- wonder if I could connect two possibly??????
