hi
over the past months i have almost totally switched between a classic needle
& grip setup to using t tech cartridges and grips. simply for the speed between changing cartridges and using both coils and rotaries.
since using the t tech grips and cartridges I've snapped 4 back springs. on two of my coil machines, both liners from tattoo me.
before using t tech i never had this problem. now the simple solution would be to stop using them and go back to a normal set up, but after investing in many boxes of cartridges i want to solve the problem.
i can't figure out what I'm doing wrong, could it be the pressure from pushing the cartridge has caused stress and snapped the back spring?
as far i know I'm not running the machines too high they operate at 145HERTZ 6V ?
i know this is a coil problem but any help or info would be appreciated.
