Greetings.
It was suggested to me that I produce torque curves for the various batches of rubber I have available to me.
I am not really finding anything to guide me on doing this. Making this up as I type...
I assume that I should standardize on a given loop size and cross-section. I'll likely use something similar to F1D motors, so .6 grams, ~0.053" width. Make up several of each rubber type.
Use the digital torque meter and a bracket for the winder so the rubber length is consistent. 10" from hook to hook is about correct.
Stretch 5x for 5 minutes, let relax a bit, then wind to breakage for max torque and turns.
Wind to 70%, let sit for a couple minutes, then back off and rest for ten minutes.
Wind to .5 oz/in or so(90%?), then back off 30 turns and record the torque measurements.
I currently use the FAI Sil-slick lube. Should I try others?
Regards.
