String Pattern

Hi:

With all the craziness going on I have been lucky enough to start a new project that will be fun!

Do any of you happen to have the string pattern for this?


Also, what do you recommend I put in it?

I have OGSM and Sensation which I suspect has been around a while but can shop for something else you recommend.

Thanks

@LOBALOT - when I get home from work, I'll look it up in the USRSA catalog and post it. If it's not in there, I'll pull one of my YFG50's and post it. They should be the same.

I would not string it with poly for sure. I'd probably opt for what you put in the OP, Gosen OGSM 17 gauge or even 18. TBH, the Sensation idea isn't a bad one either.

Thanks everyone! This one is really special to me as this was the racquet I grew up with. I haven't played with one since the summer after I graduated from high school when I broke one and have not played with one since. I really want my son to have the experience of trying it so I want to put string in it from close to that era when I hit with it.

Back in the day I strung it up very tight with a string with a hollow core and oil in it. I forgot what it was called.

-wow 18x18 pattern, haaa
-good point by @Irvin , shared holes with multis are a PITA!!
-you could still try multi mains/ syngut crosses,, to get best of both worlds
-as @Rabbit mentioned a 18g syngut cross (18g or 19g poly at low, low tension), would be my suggestion if available
-syngut is easier to thread through the shared holes, once the multis have been installed ??!!
-anyone know what the head size is on this raket??

I thought 100 but it sure looked smaller than that so last night I was thinking I would trace the inside with a pencil and try to figure out. It is fairly circular so could also just use the diameter along the width and calculate. It looks to me maybe 97.

It was called a "Midsize" back when I used it vs. the YFG-10 which was their standard sized frame.

I will measure tonight.

100? If that racket is 100 si it must be at least 3’ long. LOL

It has been hard to research. The nearest I have come to finding specs is it is 1.2 * the size of a YFG-30 which was 75 square inches which puts it at 90 but don't have anything else to go on other than measuring when I get home.

@LOBALOT
Please measure the frame's inner length and width, and use the elliptical area formula pi * L * W * 0.25 = 0.7854 * L * W as a serviceable approximation.
I can do that.

I also like the idea of putting the 16G Sensation in the mains and the 17G OGSM in the crosses not only will it be easier to string with the shared grommets but I might get a tad bit of spin out of it.

The things are heavy too. I will measure them on our kitchen scale.

I will also determine the balance. I recall they were headlight.

The racquets look awesome. I love the Black and Red with the white lettering! Very clean.

The bottom of the racquet face has kind of a step pattern where the string comes in and just before entering the grommet rests against it. On the outside of the throat there are 2 screws... can you believe it?? Philips screws... on the side holding a plate where the strings pass through and then back into the face.

I forgot all that until yesterday when I opened the box.

I had/have a one-handed backhand and I recall if I didn't catch the ball cleanly when hitting it with topspin I would catch the ball off the top of the face and shank the ball sky-high. With my eyes, they way I play today, etc... I bet that shank is a whiff!!!!

I guess I was off on the 100 in^2 :p See below link:


For head size using jwocky's calculation I get: 76.58 in^2.

The racquets are 26 3/8 in. long (Short by today's standards)

For weights and balances (measured from handle) I get:

Racquet 1: 380g, 12 1/8 in.
Racquet 2: 367g, 12 3/16 in.

@LOBALOT - sorry, the USRSA catalog I had didn't have any Yamaha frames in it. I did pull one of my YFG 50's and have pics to follow:

The pattern of the YFG 50 is a 16 X 18. Here is a closeup picture:



I hope this helps. I added a couple of other pictures just well because.

The USRSA has YFG 10 all the way to YFG 95, they have a great number of YFG racquets, but no YFG 20. Otherwise I would post the pattern for you.

YFG-10 was the smaller head size of the YFG-20. I wonder if that would work.

Thanks

Unless the racket in that picture I posted in an earlier post was strung wrong the I'd be cautious with that pattern (18x20.) That pattern will also give you 4 more shared holes. If it was me an my racket I would consider stringing that racket with a 16x18 / 16/17 ATW pattern.

NOTE FROM OLD STRINGERS DIGEST: Yamaha adaptrs (Load spreaders) for the YFG series are available free from Yahama (good luck with that.) These adaptors are necessary to prevent frame damage by providing proper support during stringing. Use the pronged (fingered) adapter at the head and flat 'yoke' piece at the throat.

Thank you for referencing that. Can you please describe what these are (if you know) so I can visualize this issue as I am not seeing anything in the shape of the racquet or string pattern which looks to me that would present a problem?

Were stringing machines different in the early 70s in how racquets were mounted which required these adapters but with a 6 point mount should no longer present an issue?

Thanks

I was thinking that as well. I don't recall it being that dense a string pattern but like my thoughts about the racquet being 100 in^2 40+ years is a long time. Let's see where this settles and then I will map out a plan.

The "load spreader" item also leads me to wonder if I want to put that many strings in the thing if I don't know why.

Yesterday I was researching Yamaha sports to search for an avenue. I was thinking that I would probably have to call Japan as I am sure stateside would just be musical instruments and motor vehicles (Jet Skis, Motorcycles, etc.).

By the way..... Is there an European/Asian or Australian version of this message board?

Maybe I can get an account there and post there for leads.

Just do a racket load spreader google search. They are use to spread an even pressure on the racket and not a single point of contact.

I googled and do have racquet spreaders that came with my stringing machine. I wonder if the staircase type pattern at the throat will give me problems though so that is a good point.

Can’t imagine how the staircase should cause a problem.

I'm sure most likely a decent load spreader would do the job. All they do is spread the forces out over a larger area. Most likely just spreading the forces some it will reduce the stress
