Love that you've overcome the poor treadle design, one spins off the spindle wheel at an angle, and with the set up originally on it, you had to spin face on, I gave up because it wasn't working, too many body contortions. Sure would like to see plans, it's a very definite improvement.
Hi...I also liked the Dodec spinning wheel (where you got the idea) however I came across yours and like it also. I am wondering if your daughters liked them and how did they work for spinning yarn? I happen to have a bike tire and handy husband and would like to try this.
