Here is a Beater I made today.
It’s made of UHMWPE. It has a 1/4" AL axle, a diameter of 53mm and weight a just under 50g.
The axle is press fitted, so there will be no glue failure (because there isn’t any).
And very nicely and is probably one of the smoothest fixed axle yoyos in existence.
$80 shipped to the US.
