I'll ask one of by brothers about this, it is his job to make such calculations. In the meantime I got an answer from my brother. I'll leave out the theory and jump to the conclusions. Suppose you have a stand/pilar that's strong enough. To make it twice as high with the same strength you'll have to double the diameter, or make it a glued or welded four ply. Without welding or glueing you'll loose much of the desired stiffnes as the wires will slide. Want to tripple the height? Tripple the diameter or use 9 plies.

Re: [lace] Re: ornament holder from Copper wire
From the diameter point of view: three circles fit exactly within one circle with a double diameter. But they leave gaps. I don't know what counts for the thrength: the mass or the surface off the cross section. In the latter case you might need about a 4-ply to fill the gaps. And then we are still talking about pull-strength, not push-strength or stiffness. Suspension bridges may use plied wire cables, the pilons never are! I'll ask one of by brothers about this, it is his job to make such calculations. It might be interesting to plait the wire around a stick or tube or thicker wire to get enough sthrength.

[lace] Re: ornament holder from Copper wire
Tamara I don't think 24-28 gauge would be large enough. 18 ga. is 1mm thick and could be twisted to form the texture and possible the strength needed. Plaiting would be a lot harder to accomplish. The twisting would 'work harden' (stiffen) the wire which should then support the ornament. Be sure to make the base heavy enough to keep it up-right. Lorri Certainly a lot of them there, thanks! Some of the simpler ones - the ones which are made with twisted wire... I think it might be possible to make one's own, using thicker wire gauges -say 28 or 24 - and plaiting, instead of just twisting (because copper is softer than brass). I'll have to take another look and think some more :) -- Tamara P Duvall http://t-n-lace.net/http://t-n-lace.net/ - To unsubscribe send email to [EMAIL PROTECTED] containing the line: unsubscribe lace [EMAIL PROTECTED] For help, write to [EMAIL PROTECTED]

Double-plied 24 (.5mm) wouldn't give the same coverage as a single ply 18 (we've been through that - takes 3 strands to double the width uniformly), but would give it the same strength. It would, also, make the wire easier to work with than a single ply of 18, by giving it more flexibility (I've tested that theory, on thinner wires - 3 plies of 34 (on one bobbin) are easier to manipulate than one strand of 24), so that a plait should be a possibility. A traditional (composed of 3 strands) plait/ribbon might be another way to get a hanger shape and a 3-pair ribbon yet another. Any of them would be more lacy than a twisted wire. I wouldn't expect it to support anything heavy, but it should be good enough for a piece of lace. Though, like I said, it needs thinking and testing :) Be sure to make the base heavy enough to keep it up-right. Um... There's more than one way to skin the cat on that one, I think. You can make the base small and heavy. Or you can make it relatively light, but broad, so it doesn't tip over. Several ornament hangers on the site Anne gave us are off the second kind. If one were to make, say, a 5-petalled flower as a base... Using 3-pair Fiandra, maybe? With a stem coming out between two petals, then curling up over the flower (not away from it)... I think the laws of physics would stop it from tipping over, even if it weren't very heavy. Yet it would be prettier than many of the hangers on the site, and more appropriate for a lace ornament. One could also - I think, make an earring tree on the same principle, but with the stem - composed of many pairs - converging in the centre of the flower then coming straight up (strong), before splitting up again, into several branches, each of which would support a pair of - lacy, of course g - earrings... Hm... Maybe another wire project for the IOLI Bulletin? What fun!
