    Posted: 02/01/2011 at 11:47am
Hi all,
 
I want to reduce the speed of a blade without changing the rubber.
 
Has anybody tried this before?
 
Maybe gluing something like a cloth on the blade will help. Any ideas or experiences?

If its varnished, sand the varnish off.

Depends on the varnish. Andro seal would make the blade slower.

Don't you have to put a lot of it to have noticable change in speed?

I think that a professional UV light would do the trick.. Stiga's CR blades are partially UV treated and the UV-treated part of the wood is slower.. I believe that you could do this with any blade and it should work.

sand down the surface, lighter weight makes it slower.

If you ever want to switch to a slow rubber...  KKT 888, rubber should be ok and really cheap. http://www.tabletennisdb.com/rubber/kokutaku-explosion-blutenkirsche-868.html

Where would you glue the cloth at? If to the handle, it would dampen any vibration. If to the blade surface, it may work, assuming you could even get the blade to adhere to the cloth.

make use of ITTF regulation section 2.04.04 to reduce blade weight, by pasting rubbers higher. leaving about a finger size space uncovered.
2.04.04 The covering material shall extend up to but not beyond the limits of the blade, except that the part nearest the handle and gripped by the fingers may be left uncovered or covered with any material. 

it will reduce weight.. and hence reduce speed.   :)

I believe this is incorrect, at least how Stiga markets it.  Supposedly it dries the wood out and makes it harder, and therefore faster.  For example, the Clipper CR WRB is faster than the Clipper WRB.

I want to make one side of the blade slower. So changing the blade wouldn't help.

I use Tenergy 25 and don't want to change it. I fel that changing thickness of the sponge changes the playing characteristics of the rubber. Don't really want to do it either.
 
My idea is sticking something (cloth , paper, etc) on the surface of the blade, and then gluing rubber on it. Need to decide which material would be best and also the thickness of it.
 
Gluing will possible be a problem too. Anything stronger than a TT glue would have the risk of of damaging the blade when it comes to remove it.
 
I searched the internet on this but couldn't find anything. I think it is an interesting project and may be useful to many people. A few of my friends say they would prefer one side of their blade slower.

There are a few blades currently available in the market which have exactly what you're talking about. They are most preferred by the modern defender, as they are all wood on one side and have a layer of carbon or some other form of composite on the other. 729 and Nexy are the only two manufacturers that come to mind, but I know there are more who make such a blade.

Most of the 2 speed blades are for defensive players. I am not a defensive player. But 729 Dynasty seems interesting. The blade I want to modify is Timo Boll ZLC. If I slow down one side it'll be perfect  for my style.

The largest determinant of a blade's speed is its overall stiffness. It's not possible to get that much speed variance between one side and the other. You can get some, but not a lot.

Get a custom made ZLC style one from that one chinese company that does custom blades. I am sure someone here knows and will respond to you about that.

unless you are a professional craftsmen i don't suggest messing with the chemistry of your blade. sealing your blade or putting some kind of sheet on your blade will make a bigger change in the characteristics. the Tenergies 1.7 1.9 2.1 don't play much different, just more control as you go down. I bet you wouldn't be able to tell the difference.

I've bought a cheap paddle with sand paper instead of rubber, then I glued on a rubber right on top of the sandpaper, felt like a great carbon blade, except it is more balanced in hardness all around the surface.
And a friend of mine tried gluing one of those thicker transparent surface protector between the blade and the sponge of the rubber (just use a normal WBG(water based glue/or tear meander), and that seems to work in reducing the speed and increase the control of the blade. I don't think this would harm the blade or the sponge in anyway, but try at your own risk....

You are right.. I recalled incorrectly.. I thought that the CR (UV treated) was slower but it was actually faster but also had more control or something like that..

The most effective way -from my experience- is to use three Tibhar glue sheets stacked on top of each other (without protective paper, just the clear sheet in each layer) to attach the rubber.

Make sure each sheet is put on the blade perfectly flat without any air bubbles.  Another thing to watch for is if your rubber has maximum sponge, make sure the total thickness including glue sheets is less than 4mm.  After you attached the rubber this way, it will produce a nice dampening effect without changing the rubber's feel.

That is very clever, you can put something in the middle of the glue sheet too, that might help. But make sure it is not visible from the side, because that is illegal.. LOL

Also makes the balance of the blade shift to the top hence head heavy.

I've noticed that playing on a slower (non-slick) table makes a fast blade much more enjoyable.
