I have worked last day on my 222 and found there is a problem with the brass ring and the turret...As the turret ring was not rolling in a free way ( it was so hard to move it inside the ring) I had to lime the brass ring and now the turret works good....
I did that because I think if the turret do not move free now the motor will certainly brake after...
So I want to know if there is any mistake of me doing this and if someone have the same problem than me...( now solved..)

Thank you for any answer!
