Hi all. I have set of modular tool posts and having problems that even thought I fastenned them realy tight with work vibration they gettting unexpectedly loose ( Possibly me being begginer too heavy with my work or bearings starting to go) where the T-bar meets the post. I tried the thred locker but with not much joy. Any tricks you can suggests or is better just to ditch them and get solid tool posts? Thank you
