Difficult U1 type THM

I couldn't judge the difference between U1 and B5 for a moment even by looking at the CCD.

(It's flat, isn't it? It slips out.)

Rather, I couldn't control my senses (sweat), starting from what I thought was B5.

Therefore, the spring part of the tip jig is curved, so I decided to use the second one that was originally processed.

(I still don't know how it bent so much. It shouldn't be necessary, but it's not good to use too much force.)

30 minutes to do this and that. .. .. ..

"Gacha"

"Oh, it's open!"

I was able to update my "sense" by seeing the images at the subsequent reflection meeting.

It was a day that made me wonder if the feelings of U1 (emphasis on operability) and B5 (emphasis on crime prevention) are so different.
