Maybe I'm being daft, but why would a washer on the bottom stop it slipping? As I said I tried it with the larger thumb screws too. At the moment I do have... one... trick.
You don't have the original screw of the PS3600 or a different batch than I. I use a washer at the bottom for the reason that the flat part of the Chudeks lie flat on the arm -> more friction, so it move less. Simple? At the bottom I have on washer and my original screws from the PS3600 supports which look very very different from yours. I can tighten it by hand and get them very firm without any movement. Different female screws will do the trick for you.
I can try putting it flat. It didn't look like it'd like up well with the pulling mechanism flat as it's already lower than the original supports. I tried the thumb screws, but I might also try going nuts with a spanner.
We can distinguish two types of common side supports: "K" shape nad "V" shape. K shape side supports always has the same size. The bottom of the frame is always at the same height.The center of the racket (grommets) is variable. V shape- vice versa. The bottom is variable, the center is always constant. This is the reason for the confusion with the heights and washers. The regular side supports (for example for Premium Stringer or Eagnas/Pro's Pro)- K shape. For badminton, in my opinion, V shape is better. It provides a better access. This is the reason why I offer v shape. Before order I'm asking about the current height (the famous draw from conversations with me- with "pink" line- the distance between top of the turntable and center of the frame). Regarding the height. I have some washers- the same shape, with square holes. I can produce any height or make a longer thread or diamaters. I have a knowoledge about many stringing machines, but I don't know everything. The feedback, observations, measures are very important. I improve my products, but I know as much as you tell me.
If I understand correctly, that means the bolt is too long and/or the acorn/cap nut (in your picture has bottomed out). Try using a hex nut instead. Also if you need to adjust the height, use jam hex nuts.
Right, pull them tight with pump pliers/spanner. Did a cheap racket at 11.5/12 and it pulled away from the one of the top supports. Didn't look like the support had moved though. Do I need to put more pressure on the frame with these?
Absolutely, you need to tighten the side supports rather tightly, compressing the racket until it won't compress anymore (within reason). When you tension the racket, it's going to expand outwards and you want to minimize any movement.
Yeah, I think I misjudged it a bit. But that's why I strung a mostly unused Ashaway racket first rather than something expensive. I adjusted the angle of the top supports too. I had set them up to be at more of a slant to fit flush with the frame, but I've turned them to be more square on now.
I recently received my order of a set of the Chudek supports from @Michal for my superstringer s90. When I first contacted Michal, he wasn't familiar with the s90. After going through some measurements with him, he got to work on it right away, and he was keeping me updated every week on the progress. When he told me the set was ready to ship, I was so exciting. After receiving my payment, he shipped out the next day. 49USD with shipping included to USA, it was best 49 dollars I've spent this year. The reason for my change of side supports was because the original supports didn't give me working space to push strings through shared grommets efficiently, and also the V contact points were not to solid in my opinion. I began looking into changing them and I remembered @s_mair recommending Chudek support to me before, so I emailed Michal @ michal.chudek@gmail.com for an inquiry. Needless to say, great quality products. Upon receiving my set, I installed them to machine, and I tested them out with a racquet that needed new string. They provided a very solid hold, and with more real estate to access my shared grommets more easily. Thanks @s_mair for your recommendation! And thank you @Michal for your excellent products!
Gotta say, after much fiddling to get the Chudeks to sit perfectly to support the frame, they've improved work flow considerably. Easy to reach pretty much every hole. I sometimes had issues with the support catching the string when tensioning some holes, and that would move the support/twist it. The slimmer profile means that's never happening to me now. P.S those AEF bases/clamps?
Yea, the Chudek supports really helped me with better access to all the holes also, and I'm never looking back . Those are the original semi-auto bases and clamps of the superstringer machine, but I think AEF is the OEM.
There is a new and better model out, and I'm using the older model, and you are using a very current weight on a stick setup, so I think there's a clear disparity as well .
This is an actual picture of how my mind feels when using an older model of a high tech electronic tension head in a higher tech age when a new model is already out.
With jokes aside, the Wise is definitely a very worthy upgrade to any dropweight or crank machine. And with the 2018 model's new improvements, I'm sure it will be an even better machine.
