Has anyone successfully used a Kif Trior tool to refit a Novodiac spring? I have tried a Kif 2.10mm tool, meant for 1.65mm springs, on a Novodiac 1.65mm spring and doesn't work, it appears an hair too large. I didn't succeed even with tweezers, surely wasn't using the right technique. Novodiac tools are twice or four times more expensive than Kif Trior, maybe an hollowed pegwood is the best choice ?
