Air bubbles in drilled holes

[Garvey]

Hi guys,

I'm a newbie and I'm really struggling to get the bubbles out of my pit resin after I drill. Does anyone have any tips? Screenman did show me when he trained me but I seem to have forgot, sorry mate :eusa_shif

Never place the pit fill directly onto the hole.

From the top let it run into the whole then place your tab. But if you do notice an air bubble just use your probe to get rid of hit.

thanks dude, I just realised I never got back to you! I'll pm you when I get a minute :p

In addition try,

1. Sewing needle to wick the bubbles out
2. Drill a little shallower when possible
3. Store your resin upside down

Lower small probe slowly into hole through drop of pit filler, lift out to top of glass and move to side to drag bubble with it. Using really thick pit filler will make the problem more likely to happen.

Hello All,
When I store my pit filler upside down I end up wasting alot. as soon as you remove the cap the resin starts flowing out. There must be pressure that builds up in the bottle. This container should also be clear so you are able to see how much resin you have left.

Agree with SGT on the drilling depth. The deeper you drill, the harder it is to avoid the bubble. No need to drill to the laminate!

When applying the pit fill, I actually place the tip of the resin bottle below the pit. Once I get a small amount of resin on the glass, I use the tip to push it up and allow the resin to run over the edge and let it fill from the bottom up. When you first get the resin on the glass, you will be able to see if there are any bubbles and if so, do not push it in until it is clear. One other tip to avoid this is remove the cap and let any bubbles rise into the bottle before allowing pushing any resin out. (this only works if the resin bottles you are using are clear at the tip or you can't see)
If you just place resin over the pit or you do not get the resin to the bottom first, that is where the bubble is coming from. The thicker the pit resin the more trouble you will have.

I also always store my pit resin upside down.As far as it running out when you remove the cap..thats not a problem as I use the L.R. "super hard"which is a very thick product.Fishing out bubbles that always seem to head right for the drill hole seems to be part of the game however.

First if you avoid the drill you dont get these problems I know some drill everything myself i have the drill out rarely if you clean the break with an awl in most cases skip the drill
That said some cant kick the addiction of the evil drill and granted it sure makes things go quicker when i do have the drill out I let the break cure under pressure then when I remove the injector and put the cure tab on the remaining resin and skip the pit filler and cure since I started doing it this way have never had a bubble Im sure others will say "Always use pit filler" but hey it works for me and has eliminated any bubble problems ive had
