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. |

|
Last Friday, During the crane per use check, I found the main power supply to to crane was shut off. I was told Don and Travis shut off the main
power before Triumf power outage. Travis restored crane main power and I could turn on the main relay on radio pedant in TH. But, I didnt
have all crane main bridge movement controls on TH raido pedant except rotation. I still have all movement controls on small trolley from the radio pedant. |

|
Gordon crane technician started TH crane trouble shooting this morning. The problem is found that there is no 115VAC power supply to energize a
main coil which is used to switch on 450V AC power supply to crane. He did a test and found the crane could be operated by big yellow pedant
in control room when he manually gave the coil 115VAC power supply to energize it.. At that moment, the crane is set to big yellow pedant operating mode. |

Gordon crane technicians continued their troubleshooting on this Tuesday. They found the crane up-limit protection switch which is installed on the same
bracket with the the crane down view camera is broken. The spring inside the limit switch which is used for pushing the action plunge out in the
switch lost its function. This up limit switch is the last protection for the crane so it is set as when it is in action the crane main contact coil |
