(August 26, 2021)
Ushiba-san showed us how to apply First Contact.
First of all, we removed the FC, that applied on August 25, with Top gun.
And we practiced applying First Contact vertically on the side of the dummy mass.
Our practice sessions are saved in the following link.

We continued to practice of FC work.
First of all, we peeled off the FC, applied yesterday.
And then, we set the dummy mass vertically with jig like this(please see photo).
We applied FC on this mass, recorded with Miyoki-san's video camera, and confirmed them repeatedly.
We practiced applying FC on the dummy mass vertically, without the jig.
And we checked the recorded video whether a brush touch the surface of the mass or not.
I measured the time it took for the FC solution to reach a easy handling state.
The solution seemed to be easier to handle 20 minutes after transferring it to the cup, I felt.
I will apply the FC on this plate tomorrow.
We tried applying First Contact on the glass plate.
I tend to let the FC solution drip to the bottom side...
| I applied the First Contact on the full glass plate with jig. It takes about 2 hours to applied the first layer, today. |
The draft chamber has been repaired ( Takase-san intermediated this work ).
I trained to apply the First Contact especially on the edge site of the plate,
but some FC solution drip reached to the jig.
I trained to apply the First Contact on the glass plate.
When I had impatience, greed and exhaustion, the FC solution dripped down to the jig.
| Yesterday, Aso-san showed me the SR2 and SR3 mirror. So I trained to apply the First Contact on the glass plate in a situation that mimics the SR2 AR side, using some obstacles. |
I trained to apply the First Contact, especially the first layer, on the glass plate.
I had training to apply the First Contact on the glass plate with the jig for BS so that I could train to apply the FC widely.
I applied the edge of the circle first, then applied from top down.
It took about two hours to apply one coat today, but I think it'll take more longer out of the draft.
I practiced applying the First Contact on the glass plate.
And I also tried to put a tab for peeling.
I continued with the practice of applying First Contact and putting a peeling tab.
I practiced applying the First Contact on the glass plate.
Recent FC couldn't peel off properly because a peeling tab didn't adhere to the edge.
So today, I carefully applied a layer of FC over the peeling tab.
The previous FC was successfully peeled off with a peeling tab.
Today I practiced applying the First Contact from a distance.
