Since the last post I have been trying to source parts and get the layout sorted in my head. Unfortunately my son is revising for his exams and he is hogging the laptop, so not had the time I need to work in CAD.
Oilite bushes purchased they will work fine.
I bought a 25H chain seems a perfect fit for the existing MY1016 sprockets. But I am out of my depth when it comes to the names and codes for sprockets and chains. I was looking on Gears and Sprockets for a suitable one to mount on my wheels. I thought I may find a cheap one on eBay but the mini dirt bike and mini atv ones look too big. The outer diameter of the wheel is around 150mm and I would like something nearer 90mm. This may limit the ratio I can achieve without more complexity than I want, >5:1 would be nice. 2750 -> 550 would still be very fast. Would need to configure the controller for logarithmic to make it controllable at low speed.
Is 04B compatible with 25H or do I need to look elsewhere? Suggestions appreciated
I'll need an idler sprocket on a slide too, or at least i think i will so I can adjust the tension/allow easy removal replacement.
Cheers
