Hi,
I've made up a formula for how to calculate the distance between the holes in
spiral lacing:
y = x/b + x/(2b2)
y....distance between two holes
x....length of the opening, from the first hole to the last
b....number of holes (without the 1/2 distance hole)
It may sound a bit weird, but it's much quicker to use this formula then to
wonder 2 hours about how to make the holes.
I give an example using the second picture (the one on the left side) on this
webpage:
http://www.festiveattyre.com/research/lacing/lacing.html
let's say the length of the lacing, from first hole to last, is 3,5cm
(1+1+1+0,5). (There you can see, the distance between two holes is 1. But
that's what you should get in the end). x = 3,5
The number of holes without the half-distance hole is 4. b = 4.
Now, count with these numbers, and you get y = 0,98... is approx. 1
So, it's right! I hope this helps a bit when making this kind of lacing. At
least it helped me:-))
