On Tuesday morning I attempted to complete assembly of the source tray for TM2 however discovered that 3 1/4-20 x 0.25 titanium helicoils had not been

|
On drawing ITA6008 for the Encole 0.5" ceramic standoffs there is a note to match pairs of ceramics to within +/-0.001". This step was missed
on the current build of TM2 source tray (ceramics were not measured).
Measured the lengths of the rest of the ceramic standoffs in inventory and they range from 0.5035" to 0.4950" in length. The ceramics |
