No, there are some Babolat rackets (and a few others also) which have only 20 mains instead of 22.
Second reason: if you string Yonex Badminton rackets, two piece is a must to keep the warranty. If you send a racket with just two knots to them, they refuse it. Also with two piece you have less...
I have two adapters. Don't know if one of them is an original.
The left one is relatively easy to build yourself. Just use a aluminum flat bar with around 5 mm (5,20 mm) thickness. The pins have a diameter of 2.95 mm and are 20,85 mm apart.
I love such "trying things". That means, that some people think about the process itself. And not just doing what others say.
What @Goat Stringer uses is the pulley principle (https://en.wikipedia.org/wiki/Pulley). Great idea!
My concerns are:
Your fix point must be higher, because the Wise...
Actually I'm thinking about to put the rackets in a box with a ozone generator. Removes the bad smeel from the grips and normally the viruses and bacteria too. But don't know how the ozone will react with the materials of the rackets especially the grips.
I string 2/3 badminton rackets. For me is 0,6 kg more on crosses the standard, not 10 %. Sometimes (and especially for my own rackets) i use 0,8 kg (~2 lbs) more. And as @Andl said, it depends on the 22x22 string pattern. I've noticed, if i strung mains=crosses, that the racket gets rounder and...
Full ack... Especially every string have a different elongation. Also some holds the tension better, some will stretch easier, some are stiffer, etc...
Here is an extreme example -> put 25 kg on a thin 1,25 mm steel rod. Now i will see the result of the SM.
I don't like the tools as an ERT or...
Hmm it seems that the factor is around 0.1579 -> 100-(mm/0.1579)=RA Value
Unfortunately i sold my RDC, so i cannot check this.
To "rebuild" the RDC, the distance from hook to the fix point in the middle is important.
The clamps are very good. Normally they fit really close to the frame and holds the string very good.
The clamp base and rails are very smooth (not so smooth as tecnifibre!). Very easy to handle them.
The tension unit is very solid, easy to hande and also have a lot of settings.
Also you can...
