Posted 7 hours ago One thing you could try is to put a couple of pucks in the lathe and machine a bit of an angle into the face of one end on a couple of the pucks say to produce an included angle of 150 deg. instead of perfectly flat.... for say 50% of the face of the puck. put them top and bottom of the puck stack and it might soften initial travel a bit.
