my new Gamma 6004 6pt SC Stringing Machine.

to be honest though, the idea and design of the clamping mechanism is really good. but for some reason the design or the machining of the T-piece, or the design of the "track" is lacking. the track is really just part of the extruded Aluminum turntable, with some sort of hardened surface. that surface just don't slide very well against the annodize base of the clampbase. either that, or they need to rethink the geometry. maybe raise the track a little.

I've always thought the cone (and the bit that contacts it) could have done with some vertical machining marks - this way they'd still be easy to engage, but the machining marks would add some sideways friction to stop the base turning under lock.

It'd be almost impossible to convert the locking type to the spring type - the lock type has a lever that engages directly with the brake pad underneath, while the spring type engages the pad via a cam shaft and a cam follower.

the issue with having any mark is that it will make rotating the clamp base less smooth.

i am surprised by the holding strength of the base. with the adjustment at pretty low setting, which means the lever action is still pretty light, it was strong enough to hold 46 lbs at the position that produce the highest rotational force on the clamp. (ie. perpendicular)

Depends whether or not the parts touch each other when the base is unlocked and free to rotate. For the record, I think they do off-the-shelf, but in your "hummingbird's wing" setting, there might be a gap.

@Biggy
Yea i also saw the 4 bolts n nuts and would be great if you can measure them at your convenience. If best you can try to interchange them and let us know
I m hoping i can buy a Gamma turntable to upgrade my spare Eagnas

i tried it yesterday and "mine" does fit .. however i had to remove the brake mechanism on the gamma turntable cuz the bearing of the eagnas was a tad wider.

i'll post some pic of the measurement over the weekend when i get a chance.

I had time to go to my friend's store and look at his ES5 the old and the new .. the yonex has some sort of railling where the clampbase rest on... anyone have an idea what it is(what kind of material)? if we can reto fit it then we can just get yonex clamp and base lol... just an idea..

Okay i just milled and machined my very own adaptor to be used on my Gamma 5003 machine's connection with the Wise, it will be less than an inch shorter than the current wise/gamma adaptor, which should give me 360 rotation for the racket. I hope it will work.

Can you post some pic when you have a chance... i have a friend that had a machine shop and i went and got a 1"x4"x 12" piece of aluminum which i was thinking of doing the same thing ... the 1/4" seems to skinny and flimsy... so i wanted to fill the whole rail on the bottom of the wise .. and drill and thread some whole ... make is a bit fuller and sturdier... what do you think?

Sure I can take some pics after I mount it and make sure it fits. I will post some pics of it this weekend I hope.

Basically it is very similar to the current adaptor, I just shaved it off by less than an inch or so from the overall length. The three drilled holes is at 10degree slant for those that are interested in knowing the drilled holes slant. Other than that...lets see, i measured the current side bar to be near 5/8 inch so I used a bigger block of aluminum that I can find and milled it down so it can adapt to the sidebar and then to the WISE rail as well. Anyways, ill try to take pics and post it soon...

with that kind of shine, it gotta be some steel, probably stainless. the other part is the texture, it has a very fine grain texture.

1" !!

how come i don't have a friend who has a machine shop.

I just received the aluminium bar (I ordered yesterday and they said 6 days shipping... heh). Will try to adapt it tonight or this weekend, I'll post here if anything goes wrong :P hehe

let me see if i can fabricate one that would fit then i can make more for those who want 1 ..

[redskins009]

As promised pictures...

Not the best quality as it was taken by my very old cellie. Ill try to get better pictures on my DSLR if you guys need it.

[kwun]

that looks better than the one Herb sells!!!

Well took me a while to re-design it and then to fabricate it using an old piece of aluminum. It wasnt hard to make, the hardest part is just to do all the drawings and measurements, but it was pretty fast to make and an improvement over the current system. if i have time ill take it apart and do a side by side comparison from the one that WISE sell and the one I have right now.

[yan.v]

Damn nicely done!

If you end up making more, I'd probably end up buying one from you! However it'd need to be like 1 - 1.5mm lower for larger grips :P

It all depends on the result of my alu bar later today :P
