Roller Weights for Daytona Variator

[sfc]

I noticed that tygerfifteen has had success with the 5s & 7s giving an average of 6, but I ask is it the same to have all 6s?

I imagine that the lighter weights will move to the outside sooner than the heavier weights and so would cause a different expansion of the variator when compared to a setup with all equal weights.

Your thoughts?

putting all weight the same is the best option, we just opt for three weights as a money saving option

So I think Dan told me that I need to get it to 6 grams average or more in order to get it into the highest gear. Does that sound right? Remember I do not have the stock variator.

Thanks

6g is a good option. Some people have gone lighter and said it works fine but with a 6g average you'll get to top gear for sure which means no loss on the top end. The stock and Daytona variators seem to both require the same amount of weight. The actual stroke (how much the variator closes in) is basically the same and the RPMs are the same so the weights should be very similar.

About the 5 and 7's. You said:

This will not happen. All of the weights will all be evenly extended outwards. It's just that the 7g weighs would be doing more of the work. The centrifical force will keep all the weights all the way out and pushing on the ramps to open the variator it's just that the lighter ones have less mass and do a bit less work. Because of this they might wear a wee bit faster but not a big deal.

You wouldn't notice any difference with a 5/7g mix vs all 6g's. It's nice to have them in 3's instead of 6's because if you wanna try something lighter you could go with 3, 5.5g and keep you 3 7g but if you wanted them all the same you'd need to buy 6. It's really not a big deal but mixing is slightly cheaper. The only negative effects I can think of are:
Little bit faster wear on the heavier weights (maybe)
Some of the ramps are taking a wee bit more stress but it's all balanced and the ramps are plenty strong enough so not a biggie.

You could actually buy 12g weights and only use 3 in the variator if you wanted. 6 weights does give more contact points so the force is a bit more spread and perhaps would drop vibration a bit.

;D ;D Great post DD, supposedly having 6 weight of the same weight will make them wear evenly and last longer, the stagger style will make the heavier weight take more abuse, however the difference should not be that significant, so playing with sets of three makes sense
