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
installed into the mounting plate as they should have been. Checked and asked around for them but to no avail. I have ordered some, they should have been
here yesterday. |

Missing heli coils installed this morning.
Threads had to be chased with tap for 1/4-20 heli coil and missing countersinks hand applied to allow for installation. Care was taken to ensure
no "swarf" was spread and operation was super clean. Chased holes blown out with canned air and a vacuum placed on the other side. |

TM4 optics tray was installed onto the old TM2 source tray yesterday and tray filled with non-active metal scrap. Tray inserted into transfer frame 95%
yesterday. During insertion the ball nut of the transfer jig became unfastened from its drive plate. This will have to be fixed before the jig can be used
reliably again however we were able to finish the job...the transfer jig is 20 years old now so it is not entirely suprising that it needs some attention. |
