Out of curiosity i have not seen this question asked before. This is more catered to high volume stringers:
If your string starts slipping, getting marked up from your clamps (even after adjustments and cleaning) is it time to replace your fixed clamps?
1) diamond dusted: i’ve seen it possible to DIY replace the diamond dusted coat. Or is replacement less of a headache?
2) yonex/toyo clamps: What do you do?
3) Is there an alternative that i’ve not considered.
I know i’m forgetting a bunch of experienced members in the forum. This is something that crossed my mind thinking long term about maintenance and support of machines.
