QOSEM Flag Gluing
[Tom R, Ibrahim]

We glued 6x of the QOSEM flags, attaching the lens (D2500277) to the aluminium body (D2500253). This was done using a jig (D2600054) to ensure the lenses were aligned to the body of the flag. We used EP30.

Only a tiny drop of glue is required, and was applied directly to the lip of the body using a thin wire. The flags will be left to dry overnight before another batch of 6 will be glued.

The flag gluing yesterday was successful, with a strong joint and nothing obscuring the lens itself. We continued and glued another 6x flags up, and will do 6x more next week
