Hey guys just wondering how hard it really is to string prestige cap grommets?
not really hard to string, but certainly not as easy as regular grommets. and like everything in life, practice makes perfect. the more CAPs you deal with the easier it gets.
yep. practice helps the most. the machine and string type affects it too
It is a little more difficult to remove the strings from cap grommets, often I cut one string close to the grommet and pull the other. Blocked holes can be a problem but not if you know a few tricks. Here is a video I made.
I would advise you to make sure you pull the string all the way through the cap, and not to leave anything on the edge of the cap, I recently strung a few prestiges and ended up snapping the crosses as I hadn't pulled the string through all the way. Make sure you hear a click or a snap when you pull it through the cap
Use an owl to make the space at the grommets bigger so you can insert the string easier.
Charge more, to encourage the guy to switch to racquets that don't have cap grommets.
I like to stick short pieces of stiff poly in skipped holes.
I always seem to have one spot where I can't get the string to pop into the slot. I have tried to use the handle of a screwdriver to push them in while tensioning, which sometimes works.
^That's a little unfair charging more for cap grommets don't you think?
Hardest thing for me is just seeing where the holes are. Once the string is in the hole, then its no big deal. But at a glance, its hard to see where the hole is. It might make it difficult, especially if you accidentally skip a hole that you shouldn't have skipped.
If you look at the grommets from the side the grommet holes are pretty well defined.
I wouldn't say CAPs are really hard to string at all... Blocked holes CAN be a pain, but like Irvin said, a little know-how goes a long way there. The only thing with CAPs grommets is that the popping/snapping sound the string makes when it slides under the slit the grommets make can be a little unnerving (to some). Other notable tips have already been stated, so I won't rehash them.
I like to hear the sound of the string snapping into the grommet. When I didn't hear it the first time (near the yoke on the outside grommets where it does not snap) I thought something was wrong.
J/k, we know what you mean. You have to be really careful when using an awl to clear the blocked hole because there's not a lot of room inside the CAP grommet so there's more risk of damaging the string you are trying to move.
In our pro shop, any requests for stringing nat gut in prestiges were refused.
Hey, it *is* unnerving when your Prestige is the third racquet you've ever strung and you haven't twigged what's making the sound!
The only issue I've ever had with CAPs was on a racquet that had four or five layers of lead under the bumper at 12. It meant the grommets didn't quite sit properly, and the gap closed tighter than it's supposed to.
That's a shame, because it plays lovely with a gut / poly hybrid.
Because of the number of strings or because of the CAP grommets? I'd string them all day long.
Seriously -- that sounds so much nicer than *Blade frames with full poly
Hand me those!
I agree with everyone else.
- Hearing the strings snapping into place through the CAP when pulling tension can be alarming if you aren't expecting it.
- Removing the string (especially thicker gauge string) is kind a pain.
- Blocked holes can be troublesome, but I've seen worse.
- Weaving poly crosses (prestige mid) isn't any fun because the pattern is so dense.
Probably a little of both? The rule was made up before I started working there. I'm sure if you really wanted gut in a prestige you could work something out under the table.
I guess stringing is so easy, even an owl can do it.
Maybe they will hire this one for the Wilson string team.
I recently got a Prestige MP grommet set and the holes are easily accessible compared the ones before that were practically closed like Irvin's photo.
sure, that's because they're not installed yet. take a pic after you've installed the grommets on the frame. then they'll look like the ones in irvin's photo.
I have been using a parakeet. No wonder I was having problems.
Using an awl to enlarge the holes (from the outside of the frame) is not a bad idea. I have done that as it makes it easier to see the hole and insert the string through it. I can also see that stringing with a super soft string like gut might be a pain in the butt. I hate stringing gut period but also don't like the way it feels, too springy for me.
I never noticed much, if any, significant difference myself between stringing CAPS and standard grommets. Except that it can be a biatch to install CAPS sometimes.
^^Where did you get the black cap grommets?
i just ordered some from TW, haven't seen them yet but they should be black and should be the same as L4L shows above.
Those grommets sure do look funny. Did they change to this type? It almost looks like you have to run the string through two holes now to close the 'cap' on the string.
The earliest CAPs I've had were from the Flexpoint, so one generation before those shown. The ones I've had have always been open like that. They close up as soon as you install them - you don't need to run the string through them before they look 'normal'.
I will admit that the first time I ordered some I phoned up the supplier and told them they'd sent the wrong ones. It soon because very obvious once I started installation.
If you look at the end of the the Cap Grommet, there will be a code usually starting with a TK???. That's the best way to make sure you have the right grommet.
I think MadDog1 is correct. I have not installed the grommet strip. I had bought the wrong grommet set for what I thought was an MP but it was actually for a Pro.
yea not putting gut in prestige is weird....
You're right, the gap closes fully once the string applies pressure. After the first install the gap stays closed.
PS I once had parrot but that guy was annoying. Owls are far more obedient and have a better work attitude. Stringing times were reduced by an average of 6.7 minutes.
I don't pre-weave much when I sting Prestige rackets. If I do I leave big loops. It's a PITA to pull a loop out. It's also a PITA to take out string on a Prestige.
Are you sure that the Microgel grommets shown are the same as the ones shown in the Prestige are the same as the cap grommets used on the YouTek Prestige which does have cap grommets?
You are all probably more knowledgable that I am, but I have one customer with a YT Prestige that unfortunately does use Natural Gut and wears thru grommets at about the same pace he does strings. I've replaced his grommets w/cap grommets twice, when I ordered most recently what arrive is the same appearance as shown on the grommet photo. When I questioned, was told that these are now the replacement.
Had one pack of each when I last strung and replaced the grommets, definately different in terms of the openings, but the grommet holes and posts aligned alike.
There have been changes in the past (notably the i.Prestige had a tapered end), but the mold itself hasn't changed over the years. Unless the customer is picky about the cosmetic (color/translucence) of the CAPs, there's no real reason not to use one version over the other. MHO.
Isn't the translucent CAP made out of teflon and the black from other material?
Not AFAIK. I wouldn't be surprised if they were from different base materials, but Teflon is pretty opaque. They may be teflon coated (they tried something similar a few years back), but I very strongly doubt they're using full on teflon bumpers. I could be mistaken, of course
I just strung my first prestige pro a few days ago, no problem at all! No snapping sound no problems with crossovers, it was great.
