| 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. | |

| 2018-01-12 | 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). | |

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 3 with ~5 mm displacement out of 34 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.
