Hmm, I’m curious about this. I’m sure someone has had to have tried this? But I can’t think of what the disadvantage or problem would be with something like this. Having two weights connected to the bottom with pulleys in the bottom corners and then going up to near the motor and back down to suspend the weight. Obviously would have to have enough length between the top and the weight to be able to extend to the far opposite upper corner, but would this not help maintain downward and sideways tension?
So here is a quick and dirty picture, although while drawing it out I thought of a couple of things that would have to be different. I didn’t draw in the current chains, everyone knows where they are I think
So, one thing that would need to be different is the pulleys at the top would have to be higher than the motors most likely in order for there to be enough length of cord to make it to the far corner. My rough estimation is it would need at least 10 or maybe a little more feet ~9 just to go from one corner of a 4 x 8 to the other, plus a little extra because you’d want to space such a thing off to the side a bit to make sure it adds some side tension as well. That is problem 1 because most machines aren’t that tall and like in my case I only have 8’ 6" to my ceiling anyway. Someone better with simple machine design than me might be able to come up with a solution to that?
Second thing is, I think it would need a second ring system on the bottom side of the sled for this as well. Fixing it on one point would be counteractive to the top rings design I believe. If it’s doing what I think it’s doing (this is just guessing since I haven’t actually built my Maslow yet).
However, it seems like if tension could be added at these points in some way, it would solve a lot of the lower corner issues as I understand them (but probably create new issues that I’m not seeing immediately).
So I just noticed that these forums apparently don’t load older posts by default unless you scroll up to get them to load. Looks like @yaddatrance Had a similar design above, but with using elasticord for tension I believe? Seems like the problem with that though would be the same as has been said for the elasticord as it is used now, not enough tension where it’s needed, and a lot where it’s not?
