victor pre-stretch function
how do you use pre-stretch function on Victor machine? would you set that function once, before stringing or every time you pull the string and clamp? thanks for all advices.

Set the pre-stretch value before you start stringing.

As Kwun has mentioned in this thread and others, this Victor model is a dream machine for many. With it, there is no fretting about upgrading to different clamp systems, after market tension heads and other mods. Everything on it is already state of the art.
Is such a machine always bought by people in the badminton business or does an individual every now and then buy something like this? At $3,800 USD it's certainly hard for any individual to justify, but maybe there is at least one BC member who has indulged at this level just for personal use?

bsmith, I think Pete LSD might be the guy you're looking for, he purchased a C-7032 (I think so) which is almost the same machine but one generation older. It has hold down instead of suspension though.

Does the Victor C-7032 have the same problem as the Yonex ES5ProTech in that you cannot pull the first cross by itself without breaking it? People always say the top end machines are so strong, but really the problem seems to me that some of those machines pull too quickly up to the calibrated tension.
I haven't yet tried the ES5P, but from memory the old ES5 did pull very quick and hard (in those days I never used any high tensions, so I never had a problem); DinkALot tells my the ES5P is much the same.

When money is no object as it seems to be with the high end stringing machines like the ES5P, I have always believed that it is a "cop out" for Yonex to say, "Oh, this is not the machine's fault. It's just so powerful that it is a small thing you just have to work around." For that kind of money, there should be no work arounds required, especially when a much lower cost device like the Wise 2086 proves that the right controls can make pulling a high tension starting knot reasonably safe to do.

I think it's fair to say that pretty much any top-end machine, apart from the Victor C-Series, has to compromise when it comes to badminton. From experience, the Yonex ES5, Babolat Sensor/Star V et al are by default set up for tennis, and have to be modified to accomodate badminton (longer billiards, shoulder support over-riders etc). A tennis string can, compared to a badminton string, take staggering abuse, so it would be OK for the motors to pull in under two seconds, and the makers have aimed to increase productivity.
I agree that adding multiple speeds to the motor would cost next-to-nothing and would make a huge difference, especially when a <£400 WISE add-on can manage it...

Since the Victor C-7032 is badminton optimized, Victor really should have given more speed control (I am assuming they didn't) so that pulling on starting knots can have the best possible chance of success. Although, to be fair, I have read from others using the Wise that even when using the lowest speed (#1) on the Wise, pulling on starting knots at high tension is still quite dicey. In this thread http://www.badmintoncentral.com/forums/showthread.php/54622-VIDEO-Stringing-A-Racket-(2-Piece-Top-Down)?highlight= DinkAlot laments how many strings still break for him. Of course, DinkAlot tries a lot of 30 pound plus tension crosses. However, Taneepak describes how a 5 loop starting knot and the use of a starting clamp on the starting knot can make a high tension direct pull on a starting knot a minimal risk affair.
For my own rackets, I am going to use a two string top down approach and will try Taneepak's method.

The starting knot should be a) BIG and b) able to slide up and down the main (i.e. it should rely on the grommet for purchase, not the anchor main). And yes, holding the tail with a starting clamp is a good way to stop it falling into the frame.
I've developed my own starter that's held even Z62 up to 30, and it can be adapted for different string gauges so it's only as big as necessary - pic below shows a one-loop "Appleton Knot" on NBG95 @ 29 - tail lies flush on the frame instead of poking into the bed. I've been toying with doing a step-by-step guide for it, actually...

Now I know what the A stands for in Mark A, it's Appleton! I guess there are a lot of ways to make a knot big, but to also make it slide easily on the main string and have the tail lie flat on the frame are unique features. I have been searching and bookmarking different starting knots such as the so called "bulky knot" and I would definitely like to have the Appleton knot to try out. If you can find the time to explain and illustrate your starting knot, I bet there are a lot of other stringers interested as well.

I'm thinking of purchasing this machine victor c7032.I was also looking at the yonex es5 pro, so would you say tht the victor machine compares or bettered the yonex machine when just stringing badminton rackets?...Also I was wondering if any owners of the victor machine can post a picture with a tennis racket frame mounted......If anyone can suggest anywhere I can either buy machine an get it shipped to uk. Also if there is a specialist place to find used yonex machines...Thanks

I have tried the Yonex (and Babolat), but not the Victor, but I have seen the Victor's tension head on other machines. It tilts upwards when the pull begins, so that the string is pulled exactly horizontally, then drops down again after the pull so you can turn the racket 360 degrees. Very nice invention, IMO.
The Star 5 is definitely one of those machines that treats badminton as an afterthought -the towers are fixed (where they move in and out with the Yonex), and this is never a good sign if they are spaced for tennis.
If I were you, I'd get the Victor and have another, cheaper machine for tennis and squash - this arrangement will be cheaper than the Yonex machine by itself. I must admit, though, that the Yonex was an outstanding piece of technology.

the Yonex is really designed for beefiness in mind. you can probably drop it from the top of the house and then it will just turn on an keep going.
it is slightly over-engineered in some way but it is that way because it is designed for professionals in mind, professionals who cannot afford to be held down by machine issues like malfunction or breakage.
all the material used is very very solid. heavy and stiff material. i have used it a couple of times and i swear it can probably served as a chair if needed.
the starting (drive?) and control (servo?) mechanism are redundant, if one of them fails, the backup system will kick in.
for most of us, this is not critical, but for someone who is stringing for a big tournament with 40+ rackets lined up each day and their job depends on it, it is worth every penny.
and that explains why it is offered at a higher premium than other machines.
