[RASMB] Assembled cells using aluminum centerpiece won't fit in rotor

[Dmitry Veprintsev]

Hi John,
we also have a problem with epoxy centerpieces that if one over
tightens the screws which plug the loading holes the cell bows out  and
does not fit.
I could imagine that aluminium centerpiece is more rigid and this problem
may be even more pronounced.
We have less of the problem since we started using 1mm thick
neoprene gaskets which are more flexible and do not need to be tightened as
much as plastic gaskets.
regards, Dmitry
