I have not had good luck with spring sourcing to find what I need, so I am not sure yet. If anyone knows of a good local source to buy small quantities of torsion and/or tension springs that would be great!!
Once I figure out exactly what I need I will get from McMaster Carr anyway....
I have also revamped the hinge mechanism that has slowed this product to market, but given us a solid hinge to use on other target options.
Sounds great! See you there!
Have you tried Standard Die?
