You need something to cut blanks from delrin rods (mitre/chop saw, Bandsaw, etc.), a lathe, and forstner bits for initial hollowing.
A metal lathe would probably be most consistent, but I use a wood lathe with chisels.
If you don’t have experience turning, it will take a lot of practice to make these well. If you already have experience with a lathe, I’d say it’s worth a try! I highly recommend starting with wood if you never turned yoyos before.
As you can see it scratched up the half that was facing the concrete as the car rolled over it. It also pushed the axle right in almost completely together.
I widened up the gap again by jamming playing cards in gap to what it was before:
It actually plays perfectly well with no sign of the axle being bent or the halves braking whatsoever. In fact, this one was a b grade and it now plays even smoother now having run over it. Lol!
This treatment would totally obliterate any wooden yoyo. This one is just fine. The Survivalist is a very tough yoyo indeed.
