Bullseye Bubble

[Anonymous]

Every now and then I come across a bullseye chip that as I try to fill there seems to be a bubble left that just won't come out. I use Delta Kits Equipment and whenever I apply pressure to the injector and resin the bubble shrinks but when I take pressure off the injector it grows back but is not evacuated, I have tried every thing I know of except for drilling into the bubble, but that dosn't solve the problem of a good cosmetic finish.
I have also tried curing the pit while I have pressure on it, but I don't like to do this if there is another way.

Anyone?

Thanks

We proabably all have this happen one time or another, and it is very frustrating. Bullseyes usually take less time to fill than other types of breaks, but sometimes we get a stubborn one. Here is what I suggest: Your first cycle on bullseyes should always be an extended vacuum cycle. Pull the strongest vacuum your equipment is capable of and leave it on vacuum for about 2 minutes. The more air you can extract on the first vacuum cycle, the less trouble you should have with bubbles. When you start applying pressure, dont go to maximum pressure on the first cycle. Do two or three cycles alternating maximum vacuum, but beginniing with half the pressure you expect to finish with, increasing the amount of pressure each cycle until you are satisfied with the results. Also be sure you have loaded enough resin to fill the bullseye. They are thirsty little devils.

OGR,

I have to agree with Grace.

I also use a DELTA KIT and draw an extra long vaccum the first time. I also use 3-4 alternating psi./vac. cycles per repair.

One thing though...Are you swiveling your bridge assy. to the side first before removing it from the glass. That air bubble might be trapped right by the injector seal and you cannot see it. Also did you try a needle to work the bubble to the surface.

Rember to keep you Pit Fill Resin upsidedown when stored as this will help prevent bubbles at this step.

Oh, are you removing your equipment when it is under pressure or vaccum?

Pay it foward,

sometimes the entry way of a break has a big piece of glass missing so use your pit filler and fill the pit first, cure it, and then drill it and fill the rest of the break as normal.

when I'm done with some breaks and I'm ready to cure there is a little bubble of air on the surface under the clear tab and thats usually what has happened, I add some more resin under the tab and smooth it till there is no more air bubble then cure the resin.
