Yusuki method on APDC

I’m new to stringing, only done 2 racquets so far. When I try and follow the Yusuki method and pulling both mains, I can’t get the clutch to release to release tension. Any suggestions? If this isn’t the best way for a beginner, please recommend what to do to start. I just followed Irvin’s yusuki method video and went from there.

I use the Yusuki method on every frame I string, including Aero Pro Drives.
There's no particular reason why it should pose any issue. The mains are started on an APD just like any other frame that has 6 holes in the throat bridge.

Just to be extra clear, you are using the starting clamp correctly, right?

Are you doing it like this?
See 6:55-8:45 and/or 11:53-13:55

Or 3:40-5:40 here...

Definitely using a starting clamp, but struggling to release the clutch, feels like it’s too tight. Any tutorial videos on apdc? I couldn’t find any when i looked through YouTube.

It actually seems no matter how I do it, I find the clutch too difficult to release.

You don't need a video for an APDC. Like I said, starting the mains on an APD is just like any other frame that has 6 holes in the throat bridge.

What may actually be helpful is something that will help you in regards to the operation of the clutch.
Different machines sometimes work differently from one another.

So, let's start with what actually matters here... exactly what stringing machine are you using?

I think the problem in our communication was with me using acronyms. I’m using the alpha pioneer dc plus and trying to string a pure storm tour gt.
I do agree the problem is with the operation of the linear gripper and clutch.

By “can’t get the clutch to release to release tension” do you mean that after you apply tension and clamp off, then release the tension from the drop weight, the linear gripper is still holding the string even though there is no tension applied? If so - then make sure when you are putting both strings in the gripper, that they are above and below each other and not crossing over each other. If you are doing that, then make sure gripper is clean (run a shoe lace with some rubbing alcohol on it through the gripper a couple of times). If problem still persists- see if light pressure on the gripper in the direction towards the rear of the machine helps release it.

I either find the linear gripper still holding the string, or in the other scenario, it takes way too much force to release the clutch in the beginning.

@Oldstorm,

Ok, now I'm on board. You were trying to convey Alpha Pioneer DC+, not Aero Pro Drive Cortex.

So, by chance, are you having this problem when using very elastic strings (say, perhaps a multifilament)?

Better yet, tell me exactly what string, what tension, and also exactly which racquet.

When you lift the bar you should release tension. If the string is not clamped near the tensioner and you have a string that stretches you will not be able to release tension. By string mains with a Yusuki method you're going to have one string that is not clamped holding tension on the gripper. I would use another method to start main

Run in the 4 center mains and hold the 2nd main inside the frame with something to protect the frame and a starting clamp. Tension the first main and clamp them your tension should release fine.

I feel like the problem is I’m pulling the string taut before putting the tensioner and it is then pulling to a higher tension than what I’ve set the drop weight to requiring a significantly greater force to just release the clutch so I can release.
This is just what I’m assuming after trial and error.
I tried this with hurricane tour at 57 lbs in the pure storm tour.

I’ll give this a try today and see where it gets me.
I’m appreciating all the help through this forum.

I used to use the Yusuki method. Now, I put a starting clamp outside the frame, say on R1 main (for example at the head), then pull tension on L1 main. I put a fixed clamp as far away as I can from R1 main (for example at the throat) then re-pull tension on the L1 main and clamp (for example at the head. Then I string two more mains on the left side and then equal things on the right side -- pull on the first right side and remove the starting clamp. If the mains start at the throat, you can put the starting clamp there. Easy peasy and it works.
