*This is how I change my bands and do my band measurements. There’s a lot of other techniques that people use, but this is how I do it*
Measure from the center of the existing band holes (or approximate where the center of the band would lie in a combined-band hole) to the corresponding fin/pin/tab/notch on the shaft. Normally, the closest band would correspond to the closest fin/farthest fin from the trigger. Once you get that measurement (in inches), you divide that number by 2 and add either 4” for 9/16” bands or add 5” for 5/8” bands.
Essentially:
9/16” = 1/2 + 4”
5/8” = 1/2 + 5”
Example:
Total distance between center of band hole to pin = 40”
==> (40/2) =20 + 4” = 24” total band length for 9/16” rubbers.
You should do measurements for every single band because distance between band holes and fins can differ. Also, this is a GENERAL way to measure “standard” band lengths. When you factor in things like different types of rubber material/construction as well as different wishbone lengths (standard is 4”), this measurement isn’t as accurate. You can use this as a guide to figure out a starting point and adjust from there. Remember, you can always cut and shorten your bands if they’re too long, but you can’t add rubber back on them. Also, try the bands a few times first before deciding to cut them. There’s always a break-in period for new rubber and it might take a few dives before your bands break in.
