Prince ports

Is floating clamps required for 50 - 50 to ensure equal pressure from the top and bottom while stringing the crosses? (03, exo3 ports)

Or... Prince racquets are strong enough? Haha

Just string it like a normal racquet and you don't have any issue. I've never strung one starting from the middle of the crosses, but I strung one normal just earlier today.

Does not matter if you use floating or fixed clamps with the 50/50 methods and ports. You would start the crosses just like you would the mains. If your machine has a table brake, then you do not have to do 50/50, maybe. What this method does is assure that the cross go towards the correct side of port. With a brake, you can prevent this. You can also use the Prince Boomerangs, a wooden dowel, wooden clothespin, a hip, whatever. I have a table brake, so don't care. What I do not like about Princce frames are that many of them can ONLY BE STRUNG ONE WAY. You have to pay attention to which side is the Short Side or where the Starting Knot is posted.

Some you can do 1 piece; others require 2 pieces if using the same string, i.e. full bed ALU. However, if you prefer to do 1 piece and the mains end at the bottom, then your other option is an ATW. That means you must plan to have the long side on the other side of the side labelled with a Starting Knot or with Short Side. That normally means the frame can only be strung one way whether you use 1 or 2 piece and the same holes are always used to tie off. Hate this because tie off holes' grommets get wrecked after a few dozen stringing unless you are careful.

I've strung my own O-port frames for many years. Unfortunately, my old Gamma brake is not strong enough so I've been using the 50/50 method on the crosses for many years. It works just fine with fixed clamps but I've never used floating clamps.

Not mandantory but it helps. When stringing O-Ports with the 2 piece 50/50 method you should string 2 crosses above then 2 crosses below center. Repeat 2 aqbouve and 2 below until you finish the racket. Can't do that with fixed clamps dedicated to one side. Glide bar machines that have a long bar for the crosses work great.

EDIT: When I used a 2 piece 50/50 on my fixed clamp machine I use both machine clamps and 1 flying clamp.

I have the latest Wise and was told by the vendor that it's safe to use the brake for this. But I still don't use it. I feel it still stresses the gripper and could cause problems. What stringer do you use? I heard from here that even with higher-end machines they are not good long term.

EDIT: But I guess it's not an issue on manual machines with brakes.

I strung my exo racquets for a long time with the 50/50 method. Strung the top half first then the bottom half. Did not use the brake. I never had any issues.

That is certainly the ideal way to string a frame, just like you would do for the mains. I've ignored that advice for many years because I'm stringing only my own frames. I paid for them so I can do what I want! No issues with the frames that I can tell.

I doubt it is ideal I'd rather go top down. I now use a clothespin to string O-Port rackets. The ones I use are round
Craft cloth spins. If you use a round object like a sharpie cap it will slide against the outer main when tension is applied. If you place the sloth in the clothespin against the 2 cross strings it does not slide and you can clamp close to the frame. I alway start pre weaving my crosses from the right side in the cross hole above the first O.Port.

I'm more worried about my frames being broken by throwing them on the court versus stringing them lol.

I've used various methods to string them, but I kind of got to the point where I pretty much gave up on all of them. The tool is not too bad if you can find them, but now I just have learned to strategically position my body in some way against the racquet handle or the machine turn table. I would never recommend my method as it's kind of hackish and sometimes a little painful, but I really despise stringing some of those o-port frames and like to get done with them as quick as possible. Some are worse than others too. I didn't really think hitting with those frames was all that special either. Luckily I don't know anyone that still hits with them that ever uses me to string. I had several buddies that liked the black frame and it was probably the best one I hit with as well, but they kept breaking them so they moved on to new frames. Some problem with the layup in that particular frame series I think.
