use thinner axlesI'm using CD's as wheels, but when I did my calculations, I got the result that my bar would need to be around 60 cm long to travel all 14ish meters. Am I doing something wrong, or do I actually need that long of a bar?
wouldn't that still be loose even with a straw? how does that get me a consistent wind every time?I put this little circular thing in on the base in front of the axle so that it would wind straight. You could use a piece of a straw but the string would probably cut through it.
