OD = Outside Diameter
(OD – ID /2) + ID = CC
Example: OD = 457mm
457-127 /2 = 165 + 127 = 292
I have this formula as an Excel spreadsheet at the office that will take both English and metric dimensions. I'll post it on the net with a link to download of others are interested.
From contributor D: I think I've got an easier way. Pace off the block your home is on. Hire next door neighbor's kid - give him end of roll and send him off running... wherever he hits pavement when end of roll jerks him silly... My formula: B-K(D) B=block
Just kidding…
From contributor K: Now if you can just get the kid to roll the banding back up! We use lots of custom colors to match laminates and sometimes we have a small roll on the shelf that might just be enough to keep us from having to order an additional roll, so I made the little spreadsheet to help us out. It only takes a second to fill out and you have a pretty good idea (usually within one coil layer) of the LF of banding. The formula actually goes back to Archimedes as he calculated the spiral: Spiral Length - N 2pi(ri+d N /2) = N 2pi(ri+Rw /2) ri is the inner radius at the start of the spiral, N is the number of revolutions of the spiral and d is the distance between the spiral. Without being able to insert the pi symbol as well as using subset text it makes the formula much harder to read. I interpreted it for the original formula and our calculator to make the variables relevant to our usage. Have you reviewed the related Knowledge Base areas below?
