우선 하판을 들어내면 나사에 접착제가 있을거에요 핀셋같은걸로 충분히 제거하고나서 나사를 푸시는게좋을듯

First of all. I really respect the guys who finished alone. I've got a few questions.

1. It could be a stupid question. should i really need soldering iron?

2. I don't know if it's worth buying a new one because of this ten-year-old thing that doesn't have one at home.

3. Is there an explanation not in the text? Please let me know if there's anything else I need to be careful about.
