Mounting/Stringing Prince Extender Ripstick 800

[SpinRail]

Hi everyone, someone gave me a Prince Ripstick to string and I'm very concerned about safely mounting it on my machine, due to my 2-pt mount and the ripstick's more oval head shape making the throat. Pictures below. Is it safe to string this stick with the throat not buttressed fully? The top mount is normal, so no worries there. (My apologies if they're too large, I set them to the resolution mentioned in the forum rules thread but this is my first post, I may have missed something)

If you have the throat supported just like any open throated racket, you should be fine. When I used to play with the RipStick, I had to restring often. Lots of "hard" weaves. Nice playing frame though. Too long, eventually hurt my arm. When stringing, I'd recommend not using a poly unless that is what the owner specified.

I would say that you don't have sufficient support as yet.

Below is a picture of something I put together for stringing the Head Ti S7, another open throated racquet. I also use a machine with a 2 pt vise. I suggest you make something similar. I used an old metal shelf support for raw material and the plastic spacers that keep the metal piece from sliding up and down the shaft of the hold down clamp are 2 halves of a core from a Gamma Supreme overgrip. I have most of the metal covered with grip finishing tape to avoid nicking the string and the padding where the metal would meet the frame is a piece of replacement grip.

BTW, I have it facing backwards in the picture. Also, in terms of support, this piece is in addition to the retaining plugs on my machine. It is not the sole means of support at 6 o'clock.

PPS: My records show that I have only strung the Ripstick on an Ektelon H. Comes with a nice assortment of throat retainers.

Well he wanted the Prince Problend, around 57M/62C. Right in the recommended tension range. What exactly do you mean when you say supported? Because here there are two points of contact inside the head, but for normal racquets that leather pad is completely pressed against the frame, rather than just near the ends of the support. I strung a different racquet a while back where there was also a gap at the very bottom part, but it was a much smaller section of the pad that wasn't in contact. I don't know how much that gap changes the amount and distribution of stress placed on the frame.

@10shoe, unfortunately the photo isn't showing up for me but I'd love to see it. What kind of 2 pt vise? Mine is beefier than most I've seen, but I'll still never feel as confident with it as one of the commercial 6-pt mounts I learned on.

IMO, you will probably damage the racquet unless you can improve the support at 6 o'clock.

I string on a Toyo Zouki machine.

It's still not showing for me, but I'll come up with something based on t
he description. Seeing as it's not my racquet, I don't think I can string it in good conscience without additional support.
