Just got a call from an acquaintance in the trade, and he asked me,
「How do you machine the shiitake mushroom-shaped spoke head
when making spare spokes for Roval?」
So I just made something up and said
「I put them on the railroad tracks at a crossing with the gates down and let a train run over them.」
Don't believe me.
If you actually did that, you'd get arrested.

The nearest rail line to that shop is the Sanyo Shinkansen overpass,
so there are no grade crossings,
and if he were going to do it, it would probably be at the crossing near Koshien-guchi Station.
Pretty impressive that he'd take on repairs without even carrying Specialized parts.
