## General Info
Gates 507C Sonic Belt Tuner
- Perform Core One belt tensioning via stroboscopic effect
- Compare to Gates Sonic Tuner
- Compare that to PF Makes and document
- Translate to Prusawire
- Frequency / PFMakes Gauge
- Translate to Positron V3.2
- Frequency / PFMakers Gauge

Ah, ezpz then:
oops, sorry I forgot to answer your original question lol Here is a handy calculator you can use. You will need to figure belt mass for a given belt using the constants below. For example a 6mm RF 2GT belt will be 1.4(mass constant)* 6(width in mm) to get 8.4 so that would = 0.0084 kg/m. The rest you can add according to your span and desired frequency or tension.
2GT RF: 1.4
2GT EPDM: 1.2
GT3 (Unitta): 1.54

VORONDesign just have to convert to g/meter for the gates tool iirc
