Fresh Rubber - never older than 90 days to guarantee best elasticity.
Top Quality Latex provide from an Industry Leader and the most sought after rubber world. Packs a punch! We have done our own comparisons measuring output. Here were our results:
Test 325% Stretch. 12" Rubber, Band Stretch 21.5", 3" Wishbone
| Rubber Type |
Band Output (pounds) |
| |
|
| Company A - Black 5/8(16mm) 1/8 I.D. |
67 lbs |
| Company B - Green 5/8(16mm)1/8 I.D. |
55 lbs |
| Primeline - Black 5/8 (16mm) 1/8 I.D. |
72 lbs |
| Primeline - Black 11/16(17.5mm) 1/8 I.D. |
93 lbs |
| Note: the Skinny I.D. bands would yeild a higher output since the rubber wall thickness is greater. |
For Primeline rubber we recommend a 310% stretch. To calculate the length of bands for your spearguns: measure your speargun band pull average (middle of the muzzle to the middle shark fin), multiply it times 2, subtract 4" (for your static wishbone) and dived by 3.1 (for 310% stretch). If you want to make more powerful bands just increase the stretch ratio to 350% but for most people will not be able to load this short of a band from Primeline rubber.
