[RASMB] torque wrench spare part

[pjgb at mrc-lmb.cam.ac.uk]

Dear Joris,

Before the current Beckman torque wrench, when they still supplied the ones 
where one had to read the pointer over a scale while torquing up the cell, 
I went to see our Mechanical Workshop.  They had no problem finding me a 
torque wrench from their tool catalogue, which was cheaper than even the 
then Beckman product (and much cheaper than the current one) and has done 
the job for the past 8 years.
I suggest that you follow the same route.

Jo
