View Full Version : Trouble starting mains using Yusuki method

Iím having problems using the Yusuki method to start mains on an Alpha Pioneer drop weight machine. As per Irwinís instructions, I string three mains on the ďnon starting clampĒ side, then tension the string held by the original fixed clamp and the starting clamp. When I achieve reference tension on that string (the one with the starting clamp), I of course release the fixed clamp and prepare to reposition it. The trouble is, before I can reposition the fixed clamp, the drop weight falls way below parallel. Am I doing something wrong here? I should probably point out that the string Iím using is a multi-filament thatís of course very elastic.

I don't think you do anything wrong. When the arm drops below 3 o'clock, hold the tension head and lift the arm up again to 2 o'clock and continue till arm stops at 3 o'clock and then clamp off.

But since the fixed clamp has been un-clamped for repositioning, the string will simply go slack, right? Or am I missing something here?

When you pulled tension on the first of three strings and clamped it off it started to lose tension then you tensioned the second then the third. All the time that first string was losing tension. When you remove the clamp on the string that had the starting clamp it pull some of the slack out of the other main.

Thanks, Irwin. I'm assuming the best way to remedy that situation is to pull tension on that first string (the one with the fixed clamp) as soon as possible, rather than stringing 3 mains on the other side before returning to that string?

That's what I've been doing, saw it in one of Irvin's other videos.
I go back to the starting clamp string right after I tension the first main.

That should help but what are going gaining? The problem is still there if you think about it. If it were me I would increase the time allowed for the drop weight to tension the each string a little longer to get most of the stretch out. By doing that you end up with the same tension but longer string so you effectively have a tighter string bed so I would lower the tension by two pounds to account for it.

Thanks, Irwin. When stringing a multi-filament that's exactly what I'll do.
