Hi Don,

I saw the jig on the bottom shelf in the little area under the stairs in 126.

Subject: [Dsg-halla_ecal] supermodule repair

HI DSG folks,
I have to repair a couple of broken lightguides on two supermodule assemblies. I plan to do this by swapping out extra crystals and lightguides from an extra supermodule we have. Taking supermodules apart and re-assembling them is not straightforward and I am wondering if you still have jigs/clamps etc that you used in the original assembly process.
Thanks,
Don
