Pulley system

[Trevor Hale]

thanks guys.

I just niticed that the pulleys on the buttom of my columns don't turn while they are under tension. I will work on that.

Hey Mr. Radar,

Glad to see you back. I have been wondering where you got off too. Did you have a good summer?

Take note that when you turn left and right on one yoke there is a great deal of tension as your top pulley tries to pull the wire in either direction and move the other yoke.

So you need a nice solid setup with the largest pulley you can fit in the column at the top of each column. so it can easily drive the whole mechanism. I used 3mm stainless steel braided wire and found this to work best. Tried the plastic coated 2mm wire but couldn't get it working smoothly with it.

We spent so many hours trying to get it to work right that I lost count at 40. Helps when you don't have the right tools

We also used 2 tensioners rather than one. Much easier to configure the whole setup. I think Westozy used one tensioner from what I can see in his pics but he is the man when it comes to this sort of stuff.

I can second this notion, I thought that bigger wire and coated would be good. It wasnt. When I build the next set, I have much better ideas of what NOT to do this time, plus Im looking into bevel gears for the system too.

Hey Trevor. Had a great summer at the cottage.

Thanks for all the help guys. I think my problem was with my bottom pulleys not turning. I will work on that.

I used pulleys from some old gym equipment found on the roadside, when we have curbside rubbish collections I think half of the crap piled up is old fitness equipment. It says something about us Aussies!!! The nylon pulleys are great for this job.

PS, Cheers Marius!

I have news for you Gwyn, We seem to have a lot of exercise stuff on the side of the road on garbage collection day as well!! So it is not just you folks!

Something is going around. I haven't worked out since weekend because I have been too lazy. I better get into it soon as I am not turning mine into another set of flight yokes

[Radar]

Man oh man!!
This is really starting to P me off!
I have it set up like Westozys' pic. When I turn 1 yoke all the way from right to left the other yoke hardly moves? It moves the right way but just inches. I tried with the tension to max , med and loose.

Should I be using a wirer like they have on a 10 speed bikes. The gear changer wirer?

The wirer I;m using is a little less then .50 cm wide. Maybe to big?


I will keep trying.


Thanks Yall

If the other yoke moves less then you need to step back and think where your mechanism is not doing its job.

Is it slipping on the pulley you are turning? Are the pulleys the same size on the top of each column?

Told you its a ball breaker
