|---|---|---|---|---|
| 2018-01-21 | Koji, Satoshi, Tomohiro | IF plate assembly | We finished attaching actuators to 18 plates. (in total 52 completed) We stored completed IF plates so that their positions correspond to the ones in the dish structure of the telescope. | |
| 2018-01-19 | Martin, Satoshi, Tomohiro | IF plate assembly | We confirmed how to adjust fixed points horizontally (with a caliper Martin bought today). We finished attaching actuators to 14 plates. (in total 34 completed) We cannot fix actuator covers as they have not arrived in Mirca yet. We also received all the threaded 700 pins we ordered last week. | |
| 2018-01-18 | Martin, Satoshi, Tomohiro | IF plate assembly | We finished attaching tube spacers on 30 plates. (in total 20 completed & 160 tube spacer attached) We stopped attaching them as the total number reached 180, enough for ordinary IF plates. | |
| 2018-01-17 | Martin, Satoshi, Tomohiro | IF plate assembly | We finished attaching tube spacers on 30 plates. (in total 20 completed & 130 tube spacer attached) Eduardo brought 150 threaded pins to Mirca. | |
| 2018-01-16 | Martin, Satoshi, Tomohiro | IF plate assembly | We finished attaching tube spacers on 35 plates. (in total 20 completed & 100 tube spacer attached) | |
| 2018-01-15 | Martin, Satoshi, Tomohiro | IF plate assembly | We finished attaching tube spacers on 36 plates. (in total 20 completed & 65 tube spacer attached) | |
| 2018-01-14 | Satoshi, Tomohiro | IF plate assembly | We finished attaching tube spacers on 19 plates. (in total 20 completed & 29 tube spacer attached) | |
| 2018-01-12 | Martin, Satoshi, Tomohiro | IF plate assembly | We completed 11 plates and finished attaching tube spacers on 10 plates. (in total 20 completed & 10 tube spacer attached) | |
| 2018-01-11 | Martin, Satoshi, Tomohiro | preparation for IF plate assembly | We removed 351 unnecessary aluminum plates from actuators and 700 small pins to be threaded. We also confirmed how to assemble IF plates and completed 2 plates additionally (in total 9 completed). | |
| 2018-01-10 | Satoshi, Tomohiro | arrival in La Palma |
Trouble Shooting
Tips
- Some of actuators have watertight belts so far from their tops that IF plates cannot be adjusted to the right positions vertically. We found 4 with ~5 mm displacement out of 52 so far. We may have to replace the belts with new ones (Martin said there are belts fixing with screwing here in La Palma.)
- Bolts for fixing tube spacers have square shapes under their hats. Some of the square shapes are tight and difficult to slide smoothly. We might not use them.
