Hey guys, we've all been through it, you find a great blade only to find it's too heavy heavy due to the hollowed out handle. Was wondering, have anyone tried to un-WRB a blade? What did you fill it with...I read a while back that someone used hot glue...any other suggestions? ------------- (\__/) (='.'=) But there's no sense crying over every mistake, (")_(") You just keep on trying till you run out of cake. |

I turned my stiga offensive wrb into a sweet spot transformer, by putting a long bolt ~ 10cm long from the base of the blade and inserted 3 nuts in the hollow blade section. the nuts can be adjust up or down. It works Perfect for me.
(warning: drilling the hole from the base blade need to start with small drill bit first, otherwise, the blade will crack!) |

I've used Evostick Wood adhesive to fill in the hollow handle of a mark I Wavestone. The weight went up from 88 to 96 grams, however the blade is no longer head heavy and the benefits are : * A well balanced blade, that feels comfortable in the hand. * You are less aware of its weight. * It plays better in the short game and has more feeling. * It feels like you're playing with a much better blade. * My recovery time between shots is actually better. In my experience head heavy blades/bats have a slightly slower recovery time, than a balanced blade/ bat. ___________________________________________________________________ A WRB handle has a clear lens and it is possible to prise that out, which gives you the way in to fill the handle. The other route is to prise off one side of the handle, which is a bit harder than prising out the lens. Then fill in the handle/prised off handle piece and reattach the handle piece. |

Get lead tape and wrap it around the end of your handle. The adhesive backing will keep it in place. It also has the benefit of allowing you to undo the weighting if you dont like it.

I used to use silicon or wood glue, but it looks uglier than lead tape and is permanent.

hmm, interesting point. btw, for those who managed to fill in the hole...how did you get the plastic logo off?

The plastic logo is balanced on 2 small ridges at either end of the logo. Use a modelling knife to cut through one end and that should help you. I took the other approach taking of one side of the handle, which took longer. Another option is drillling a little hole in the lens and filling the handle that way. Evo wood adhesive is a glue that you use to glue two pieces of wood together and it provides a solid bond. You must have an equivalent in Australia, available from a DIY shop or a timber merchant. |

Perhaps you can use a hair blow dryer to heat up and loosen up the glue on the logo, it should help to get it off easier.

I actually held the blade by the rubbers and hit the handle on a wooden surface covered with cloth a couple of times and the plastic lenses came out, both of them (each when I hit on the corresponding side). No damage of course. My blade is an OC WRB and there are no hinges, just some very small remains of glue, almost nothing. It is though around 10 years old... :-) BTW, the idea to place a bolt and nuts that can move up and down is pretty clever!  ------------- Darker Tanpan, fh 729 higher 2.0mm, bh 729 geospin 2.0mm http://mytabletennis.net/Forum/forum_posts.asp?TID=28707 - My for sale thread |

Lead tape could be put on the very end of the handle (where the company badge normally is) to avoid exposure to your skin. You can probably find lead tape with an adhesive back anywhere they sell golf equipment, since many people use it to change the swing weight of their golf clubs. ------------- F3S | Tulpe T-7007 | F3S |

You can also find them in the tennis section of sport equipment stores such as Academy, Sport Authority.... There are two types, self-adhesive to stick on the tennis racket frame and none-adhesive to wrap in the handle. But lead is a health risk. Who knows, you may touch the lead, then pick up a piece of candy and give up to your kid or something. If it was me, I would just buy another blade. |

Ok thanks a lot guys! After several cuts and a burn, I've managed to fill my wavestone with hot glue. It went from 85grams to 90grams, CG shifted back towards the handle by 6mm.

WITH PAIN!!! not seriously, I grabbed a screwdriver and went to town on it...hence the cuts and the burn from the hot glue. I find it has the exact same vibrations before it gets to the un-WRB'ed part....ie, with a standard shakehand grip, you'll still feel the vibrations in your fingers (contact point), but the vibrations in you palm is GREATLY REDUCED! this is just excellent. ^_^ ------------- (\__/) (='.'=) But there's no sense crying over every mistake, (")_(") You just keep on trying till you run out of cake. |

You just pried the logo off with a screwdriver??? Didn't it break, or get scratched or something?
I like the idea of the vibrations being greatly reduced in the palm. I have an 81g K-6 that I may try this with. How much glue did you have to use? The K-6 seems to have a pretty big hollow spot, and I don't want to increase the weight by more than 5 grams. ------------- F3S | Tulpe T-7007 | F3S |

if you're afraid of adding too much weight, I'd recommend you skip the experiment, since if you don't add enough weight, the CG won't be shifted back far enough. I used a whole new hot glue stick.

Some people have filled the handle with insulation foam that comes in the spray can. It has that plastic straw that's nice and thin. Easy to insert. It works well to stop the rattle from the trasformer blades. If weight was an issue you could put something in there and then foam around it. ------------- Wavestone St with Illumina 1.9r, defender1.7b Please let me know if I can be of assistance. |

The expanding foam idea sounds interesting. I'm not as interested in shifting the CG as I am in deadening the vibration. But I'm still a bit worried about screwing up the handle or the plastic logo getting the logo off. ------------- F3S | Tulpe T-7007 | F3S |

OK, I figured out a minimally destructive way to get the logo off. Get the smallest jeweler's screwdriver you can find. I have one that has a blade that is very thin and only about 1.5 mm wide. As mentioned by someone earlier, the plastic logos seem to sit on little ledges supporting the ends of the logo. There doesn't seem to be a ledge in the middle. Just carefully insert the tip of the jeweler's screwdriver in between the edge of the middle of the logo and the wood of the handle surrounding it and gently push in and pry up. Pops right out. Or at least the one on my old Stiga premade wrb did (didn't want to try this experiment on my $50 K-6 until I confirmed it worked well). Causes a very small blemish to the handle, but nothing you would even feel once you pop the logo back in. ------------- F3S | Tulpe T-7007 | F3S |

For minimizing the vibration without increasing the weight or damaging the handle from the foam expansion, couldn't fitting it with cottonballs or something similar work? Actually I think I will try that and see how it changes the blade... :)

the cotton balls may become dislodged when you play,expanding foam is sticky(carefull not to get on hands)and won`t dislodge,it won`t damage the handle if you overdo it with the foam it just keeps coming out of the end of the handle ,you can sand it nice and flat when it settles------------- Black Balsa 3.0 fh/tenergy 05 1.9 388d ox |

Firetack, you did this with a Donic blade that has an open end. With my blade, I will have to "cap" back up the handle with the logo, which would mean having to sand it round and lower than the rest of the handle if I get to much in it.
Hmmm.... nothing seems perfect yet. ------------- F3S | Tulpe T-7007 | F3S |

Well, I did it to my K-6. Prying off the logo was a little bit harder than it was with my Stiga premade, so the blemish is a bit bigger. The logo didn't go back in perfectly flat either, so there is a little bit of a ridge around one end of the logo where the plastic logo is a little bit lower than the wood. But it's nothing that bad, and I took the plastic logo of the backhand side of, so the forehand side of the handle where your fingers go is still nice and smooth.
I used Dow "Great Stuff" for gaps and cracks.
 It does continue to expand after you put it in, so you need to be careful how much you put in. I actually overdid it just a bit, so it kept expanding up through the spot where I pried the logo off, but it wasn't that big a deal.
The foam only added about 1.5 grams to the weight of the blade. It went from 81.1 to 82.6 grams. I think this is considerably less additional weight than using hot glue would have added. I weighed the 2" hot glue sticks and they are 2.2 grams each. I think it would have taken at least two and maybe three of them to fill in the K-6's hollow spot.
The test will come tomorrow when I play again and see if the foam cuts down on the vibrations of the K-6. I'll post again after I play with the results. ------------- F3S | Tulpe T-7007 | F3S |

Well, I would say the experiment was a success as far as reducing vibrations goes. The K-6 feels much more solid now, with greatly reduced vibrations.
However, the logo not being in completely even and flat bothered me a bit more than I expected, even with it being on the palm side of the handle. I may try to take it back out and see if I can get it back in straight and flat.
Overall, definitely worth doing if you want to reduce vibrations and get a more solid feel to your wrb blade! ------------- F3S | Tulpe T-7007 | F3S |

good to hear it worked for you,regarding the plastic logo you could turn your blade and rubbers round if resticking plastic logo fails,or add grip which will reduce vibrations even more ------------- Black Balsa 3.0 fh/tenergy 05 1.9 388d ox |

Thks guy ! I've also "un-WRB" a Clipper Cr WRB. Orig weight was 82g. Took of the plastic logo, fill it in with expanding foam. Did the same mistake as brainstorm, put too much...Not big deal, just take off the extra-foam during the expansion. Aim wasn't really the reduce vibes, because vibes weren't really noticable but preferably to make balance better. It was too head heavy to my taste. So during the foam drying process, I was balancing the blade from the center in order to bring it to 4cm to the handle (that's my best comfort). The foam was too light to do the job so I added one metal mini-disc (2g) in the foam. Once dried, it doesn't move. Re-sticked the plastic logo, sanded the handle, put a grip and....was exactly 4cm balanced ! Blade's weight went to 86g but it feels lighter in my hand due to the better balance. Vibes (which were almost unnoticeable) had totally vanished. Sticked two new sheets on it and went to play. Hmmmmm, juicy ! Fantastic blade. Altogether, this process made me change my mind about WRB. It is finally very usefull for players, such as me, who know exactly where is there best balance distance from the handle and can therefore "customize" their blades accordingly. ------------- Joola Wyzaryz Freeze Vega pro 2.0mm Vega intro 2.0mm Blade collection : https://photos.app.goo.gl/PrgCu5ib5RnhVXTn9" rel="nofollow - https://photos.app.goo.gl/PrgCu5ib5RnhVXTn9 |
