[RASMB] torque wrench spare part

[John Philo]

Joris,

I've never had any made myself, but I was told by a Beckman service person
they are made from "spring steel" (sorry, I don't have any more specific
information), and that they can be made by most machine shops.

Dear all,

Recently I broke the small metal bar located in the bottom of the turnable
rod of the torque wrench, with which you tighten the cells. Unfortunately we
do not have a spare one. I tried to let the local technicians (whom are
normally really equipped and efficient) make me a new one but they convinced
me that this is some special hardened and polished kind of metal. So I
contacted the Beckman field service and heard that this thing is around 500
to 700 Dollars. Rather expensive for a really small piece of essential
equipment for the analytical ultracentrifuge. My question is if anyone found
a cheaper source for this small metal bar?

Thanks in advance.
Kind regards,

Joris
