Did my first conversion way back in seventh or eighth grade.
Think it was a Taiwanese 80s boom bike my uncle gave me. He helped me strip and paint it but I did the rest myself with the guidance of some books on the subject. He also supplied the parts and tools.
My skill level was probably no greater’n what you describe yours as now.
Took a lot of time and work and it didn’t come out that great but it started the ball rolling.
