Reusing old rubbers

[ZED]

So i have been gluing and cutting near 50 rubbers now, so i feel that i have some solid experience.

However, every time when i took a rubber off one bat and put it on another, it was dead.

I put a 729-FX on a gambler carbon about a year and a half ago, and it died (note there was a large amount of residue when left when it was glued, i barely knew how to glue at the time)

I put a 729-08 on a yinhe t-11+, and that died too. This time there was minimal glue residue and no splintering. I don't think the 729 rubber comes with its own glue layer. This time i have no explanation.

Now my gluing procedure starts by applying a very thin layer to both blade and rubber. I usually apply a bit more to rubber to let it soak. After about ten minutes, or after i can't see the white glue, I'll line it up and press it down. After i made sure there are no bubbles, i would place a heavy book on it. After 5 minutes, I'll take off the book and take a knife to the rubber. With both knife and scissors i can achieve a more or less machine cut, although i prefer knife.

It should be noted i use butterfly free chack.

I am soon gluing a tenergy 64 to a viscaria, so this is a kind of high stakes operation.

So,
Any tips on gluing used rubbers?

Get rid of all the glue that is on the sponge, often easier said than done. A very light coat of tuner oil often softens up the rubber cement glue so you can rub it off into a gooey mess.

Once sponge is free of glue, be sure to brush the glue into the sponge fully. Instead of making 1-2 passes, you need to push down on your brush some and work very rapidly with circles overlapping to make sure the stuff gets into the sponge pores. Failing to do that will get you inconsistent results. Of course one should get rid of build up on blade. Some blades are sealed to well or have a very smooth surface that makes it difficult for the rubber to adhere to the blade and that makes it easy for the sponge to break contact with the blade and a dead feel. The solution to that is judicial use of sandpaper to rough up the surface just enough, it takes judgment and touch, but so does playing TT so you will be fine.

Thanks for the advice,
When you talk about getting the glue off the sponge, do you mean those little balls of solidified chack, or do you mean any glue that settled in the pores?

And when you mean to brush the glue into the sponge fully, you mean to use the normal amount of glue right? Just checking.
