for that detail lindros. Does the stringer tension correctly? Also, is it really worth it to buy this stringer or should i either save up for a more expensive one?
Tension correctly, you ask? How do you want me to answer this question? I could give you my opinion, but are you looking for me to do a test of some sort? As far as I can tell, it seems to tension correctly and my results seem to be repeatable. I did actually buy a fish scale a few months ago with the idea that I'd hook it up to the machine, pull tension, and then see if the scale matches the digital readout that I set on the machine. But I haven't done it yet because of two reasons, I guess. 1) I remember reading that I'll need to check the calibration of the fish scale to make sure it is correct. For instance, I'd need to hang a 50 pound weight on it and see if it reads 50 pounds. Well I don't have any spare weights laying around - although I do have a couple of 15 pound or 20 pound dumpbells in my basement. Would they work/Are they necessary? I don't know. Also, when I hook up the scale, I will also be able to see if the tension drops and what the "trigger" is for my machine to "re-pull" since it supposedly has constant pull and I hear it clicking (repulling) every so often. Granted, I don't think the constant pull has as low a threshold for repulling than a linear electronic machine has, but I still feel as if I can get very repeatable results, (and IMO, more repeatable results than a crank machine since the initial pull will digitally always go to the set tension even if there is a little or a lot of slack in the line to start. But I have no experience whatsoever with crank machines, so I could be way off base on this). The second reason I haven't hooked up the scale is because I'm not sure exactly what to tie it to or if there's any other details I need to know. Granted, if I just started to tie a string to it, I'd probably see that it's not rocket science. But in any case, I've been lazy and haven't done it yet. Perhaps in my next spare time, I'll research some other threads where there are pictures of others that did it.
Sorry for the extremely long feedback on this issue, but basically I don't have firm data on the machine's accuracy other than "it seems to work great for me."
Next you ask, "is it really worth it to buy this stringer or should i either save up for a more expensive one?"
The over-riding theme that you'll see around these threads and in the stringing machine section is that you typically get better quality and features with the more money you are willing to put into your investment. Essentially, "you get what you pay for" when it comes to these machines. But then again, these machines are not extremely complex, and some people seem to say that you only need a machine to hold the racquet, pull tension, and clamp... Hopefully you can get more feedback from others with more expensive machines if this is a possibility for you.
