Undulated Wavy Weavings
Usually when sizing these, use the .85 multiplier.
Final size ∕ .85 = weaving size
These lay out well with the 1.5” pipes and the 4.5” spacing
Usually the ‘ups’ on the weavings are spaced at 5.25” – 5.75” intervals
5.5” layout spacing / 4.5” pipe spacing = .818 – however, remember that the weaving will usually relax out to a larger size
it is fairly easy to spread out a weaving by pressing on the ‘ups’
it is much harder to contract a weaving that is too wide
If you did some other kind of mathematical relation other than .85, you can adjust to the final size this way
If you are too large and want to get smaller without flattening and doing a new layout, choose a smaller spacing
4.25” pipe spacing, with 5.5” layout spacing, will give you .773
4.75 pipe spacing, with 5.5” layout spacing, will give you .864
remember to leave room for the piece to relax and spread out
Wire-brushed weavings need to be aggressively torched on the back, only lightly on the front. This will anneal at least some of the copper and help eliminate the ‘springiness’ resistance to shaping
Alternately, larger 2” pipes can be used – this will help prevent bottoming out and will give a gentler larger undulation
A 5” pipe spacing with a 6.25” layout spacing will give you .80 – again this will probably relax out to the desired size.
Probably 2” top pipes should be used in conjunction with the 2” bottom pipes
The poles must be attached precisely parallel to the edges
Also, when trimming the edges of the wavy weavings, the edges must be as parallel as possible
This would be a strong reason to draw the outside edges after the weaving is woven, since the geometry can change with the weaving.
Note that the pipes should be secured to the wood jig with screws, not clamps. The clamps tend to slip. The jigs should be kept parallel to the table and the piece laid on the pipes as perpendicular as possible.
