RE: Torque Stand slackness

Andrew,

I have the same problem as you did. Increase the pressure on the handle does
not work and it will certainly broken the handle . Try to place a small
pierce of fine sand paper(600) between the cell and the cell holder will
probably do the trick.  It work very well for me.

My torque stand seems to be losing its grip! I don't think it's
the actual collet that's the problem, but whatever holds the
position of the handle. Rather than use excessive force on the
handle to keep the cell in position while tightening up (which I
suspect may be what leads to the broken handles discussed lately),
has anyone found a way of reinvigorating torque stands? I was
considering taking mine apart to investigate, and wondered if
fellow centrifugalists had any views or tips?
