I was wondering if anyone has tried putting a 1" copper plumbing end piece on the end of an alluminum/TI staff? It fits really well, and would be easy to secure in place. I am curious about it. It would protect the dowels from the flame (metal tape wears away at some point) as well as the end of the staff from getting beat up when dropped.
Plus since it adds weight at the very end of the staff it increases centripetal momentum in the most efficient way possible. The further from the center, the less weight you need to produce more swing momentum. I use 8-12" dowel, and have tried staffs with 1/2" by 3" lag bolts and didn't really like it that much.
I am also thinking of putting 2- 4"of wicks to make 8"s of fire, at about a 1-1"2 to 2" thickness. Lots of fire good, especially cause I am 6'4" and end up using staffs that are 65" to 70"s. I almost need the 8" wick.
The only fear is that the copper will for sure conduct a lot of heat, and if it comes in contact with skin it might burn very very quickly. Most of the cap would be under the wick, except for the part over the tip of the staff, and I don't seem to catch myself with that very much, so I think it might be low risk. Though really shitty it is did stay on you for any length.
Any thoughts, feedback? Has anyone tried this or heard of folks trying it?

Re: Copper tubing as an end cap on a staff?
Wed, March 12, 2008 - 6:21 PMIt's not a bad idea, but the problem with copper is that it passes a lot of heat. If it's sticking out, even a little bit, it will pass all the heat it collects back to the wood and aluminum. Oooh, AND the kevlar. This could very seriously change the way your wicks work (larger, shorter burns would be my guess).
[BTW, metal tape isn't supposed to last forever. It's supposed to allow the end of the wood to char, which protects it from burning later.] -

Wed, March 12, 2008 - 7:47 PMThanks for the input, very helpful.
Yeah the heat conduction could be a real issue, especially if it's messing with the wicks. Probably vaporize the shite out the fuel at the tip and cause an uneven burn. Not sure what the tubing and wood would do if there is an extra hot spot at the end. My other thought is that it could take a long time to cool enough to re-fuel the wick. I would also guess it would being really dangerous when trying to snuff it out if it got touched, probably even through a nomex cloth.
And I am guessing aluminum tube ends are not around, and even then are so light it wouldn't really add swing weight.
Maybe that big old lag bolt really is the best answer running. Trying shorter then 12" dowels too seems good, I really didn't like my friend's that had 12" and a bolt.

Thu, March 13, 2008 - 12:35 AMOne of the things I did early on was to take a screw and a washer and cap the end that way. You can get aluminum washers and drywall screws should work. -

Re: Copper tubing as an end cap on a staff?
Thu, March 13, 2008 - 4:49 PMmanufacturers have been lowering the quality of drywall screws for a while (i am a carpenter)
it might be fine, but i would prefer to use a deck screw on that.. -

Re: Copper tubing as an end cap on a staff?
Thu, March 13, 2008 - 6:24 PMIt's not about strength (quality) but on heat conductance and weight. Drywall screws have a very high aluminum content making them most similar to the aluminum tubing that has become standard. It takes very little strength to damp cloth on a tube. -

Re: Copper tubing as an end cap on a staff?
Thu, March 13, 2008 - 8:59 PMI have two questions that almost go with this thread. The first being where to you usually buy metal tape? My other question is what is the best type of screw to use for securing Kevlar on the end of a staff? So far I have only been spinning poi, but I was thinking of making myself a staff.

Fri, March 14, 2008 - 12:24 AMHardware stores (keep looking) or auto parts stores (muffler tape)
Any screw will work, self-tapping are the easiest. -

Re: Copper tubing as an end cap on a staff?
Fri, March 14, 2008 - 8:44 AMI'd just like to throw my 2 cents in.....
Make sure the screw you buy has a rounded head on top and flat on the bottom. II dunno what they are called but if you get the screw with an angled part, they tent to snap off sometimes when dropped.
(|=====> good scew
|>=====> bad screw -

This is the maximum depth. Additional responses will not be threaded.
Re: Copper tubing as an end cap on a staff?
Fri, March 14, 2008 - 8:47 AMlike you say Tedward, they may be good enough...the problem i have with them (drywall screws) is that the heads pop off...

Re: Copper tubing as an end cap on a staff?
Fri, March 14, 2008 - 1:47 PMCountersunk washers are helpful as well. I'm pretty bad to my wicks, not having adequate covers for them, and without washers the screws ended up slipping through the outter layer of kevlar. Small, probably 1/4" diameter, countersunk washers fixed it well. -

Re: Copper tubing as an end cap on a staff?
Fri, March 14, 2008 - 2:08 PMOkay, I guess I'm off to the hardware store again to see what I find.
Thanks for all the suggestions.

Re: Copper tubing as an end cap on a staff?
Thu, March 27, 2008 - 8:33 AMI make wood staffs, and fireproof the heat-affected zone with copper foil. I use copper foil to clad the ends as well.
I build my staffs with the wicking roll overhanging the shaft by about 1/4", so that it acts as a bumper and makes the hot tip harder to contact. Admittedly this does increase wear and tear on the wicking by some small amount (most drops are going to abrade the wicking no matter what), but it seems like a reasonable tradeoff.
I prefer to regulate weight at the ends just with the amount of wicking. I've yet to meet a staff spinner who says "I want it to be heavier at the ends, but with *less* fire." (!) -
