Good luck with your modem.

The wheel is a interesting concept.
Do you have any experience in practice?

Sorry to say not from me at the moment.

I need a clear run on this one of a couple of days to weld up pieces etc etc
Cannot do that at the moment as shooting off here and there doing stuff.

When back in a routine will crack on and have a go.

If only you could get paid for playing with this stuff, would make life and time more easy, but got to put food in the mouths other ways hehe

Cheers

Sean.

I have noticed one thing with a lot of these Gravity Wheel designs... The parts that do the pushing, nearly always seem to be near the outer edge, or or somewhere between the halfway and outer edge.

It is harder to stop a wheel from turning if you try to grab it at the axle, and that is why I have been trying to conceptualise a design that has all of the pushing parts, as near to the axle as I can get.

Keep up the good work guys.  ;)

@Bulbz

 You need leverage to get your power to the axle and in a gravity wheel, the further the weight is from the axle the more power at the axle their will be.

I think you misunderstood my point...

I don't mean put the weights in the centre. What I mean is have the cam and followers (or whatever method of actuation you intend on using) in the centre, and have cables or rods connecting the followers to the weights on the outer edge.

 Yes I do believe I miss understood what you meant.

But lets look at the wheels. I you want CF support for quick movements you will need it inline with the axle but out to the edge to get full effect for you shifts. But If you want little CF you will want it closer to the center. You have to understand how fast the shifts will have to be in a wheel doing just 60 RPM this means you if you have 6 weight shifts per turn you will have to make your shift in 1/6th of a second.
