Hey all, good thread going. I will sticky it after we do a little work on it, as I tend to try to get rock solid info in stickies. There are a few things that I slightly disagree with, but it's all a matter of pickiness on my part:
1) There is a difference between electric machines and electronic machines, IMO. Electric machines are machines that utilize electricity in order to power the tensioners. This does NOT mean that a machine is a true constant pull (all electronic machines are electric machines, but not vice versa). Electronic machines use sophisticated electronics (typically printed circuit boards with load sensing/tension monitoring electronics). These machines are typically (very close) to true constant pull, and are the "expensive" electronics you speak of.
Lower end electric machines only have very rudimentary "electronics," and they typically work with the use of a preloaded spring, just like a crank. IMO, the ESII+ is right in between true CP and crank, it adjust far less than my Laserfibre MS200TT (and I've had about 2 years of high volume stringing on one). It adjusts, sure, but not to very minute differences. I remember reading Gamma Tech commenting on the amount of change required for the tensioner to re-activate. I remember it being a pretty decent number, but I can't recall it off the top of my head.
As far as flying clamps, they can actually be FASTER than fixed clamps. Another (not widely used) name for flying clamps are "speed clamps." When you get used to flying clamps, you can really speed along a frame. I think this is slightly off. Also, I would also say that the industry's finest floating clamps are the Laserfibre brand. I also found the SP flying clamps to be better than the Klippermate clamps, which have been known (in the past, not so much recently) to have a few quality control issues (sharp edges which would break strings repeatedly)
Mansewerz - "A linear gripper causes less damage to the string because you don't have to wrap the string around it which bends the string and causes kinks (sharp bends in the string). Also, the linear gripper is pretty simple to use. Just put it in, and tension."
Rotational grippers do not bend the string or cause kinks in the string.
The clamps on any stringing machine are more likely (than any gripper) to cause string damage if they aren't adjusted properly.
I have to agree with Bud here. A linear gripper in theory does not cause less damage to a string. The linear gripper relies strictly on the force of the gripper plates to smash the string and hold it in place (in more or less words). This is fine and dandy (since there is often a limiting screw on these plates), but a rotational gripper is often more gentle on the string due to friction as well as a tightening of the drum as necessary. I do agree that bends can occur, but any good rotational gripper should have a slight bevel to it, but this isn't always the case. It's all a sticky situation because there are well designed ANYTHINGs in the stringing machine world, and this is another one of those situatinos.
Put some poly into a rotational gripper and watch the string turn into a white color at the point that it is fed into the jaws after being wrapped and tell me that no bending is occuring there.
I rarely see polys change color due to bending, unless it's really bad...?
Also: Automatic dropweights: I'm not sure this category really requires it's own subcategory. I would put a note under regular dropweights, as the only machines that I am aware of that use this tensioning system are the LF machines and the SW machines. (Much overlap in this). Although honestly i don't think this needs to be changed, it's just a nitpick.
Mansewerz, I really like where this thread is going. Please shoot me an e-mail through the forum, or diredesire @ hotmail (they go to the same place).
I'd like to have a chat with you and see what I can do to clean this up and make it sticky worthy. I'm hoping some time this summer we can get a good S&S/SM forum stickies going, and there are a few good efforts going on right now. The only thing I am questioning at this point (in all the threads going) is the matter of opinion. If I put a sticky status for any threads I want the information to be less opinion, and more objective, as you stated in your first post. This effort is really looking pretty darn good, though.
