Not a runner... but a skipper

I can write the whole lead in story if it will help, but what

When you pop a bull you are terminating the end of the crack. It is tricky and takes practice to know where the crack really ends.

If the crack continues to grow on you when you try to pop a bullseye then you didn't drill the whole deep enough.

or maybe, not drilling to the correct end of the crack.

Ditto what Coister has said.....

Yeah... drilling too shallow is probably the reason

I learnt a hard lesson once and ensure that it does not happen again. Part of my learning experience i guess. This particular vehicle had a 14 inch crack. Evaluated the crack, drilled a hole at the end of the crack and tapped the needle for a mini bullseye. I freaked when the crack extended by another 2 - 3 inches. Relooked at the crack area again and discovered that it wasn't on the outer but the inner area of the windshield. I always ensured after that to identify where the crack is rightfully located.

Hope that this may be helpful to some on the forum here.

Coitser is right--- typically when a crack just keeps on trucking, it means the hole was not deep enough.

Although, last month, I encountered a crack that would completely dissappear unless I heated it. Always make sure the crack you're about to repair is up to a warm temperature.

Giving a good 1/4 inch lead on the crack's head is a good idea, too. Not all cracks come to an end where they appear to--- and aside from using physical pressure (bad idea) to flex the crack's tip, it's hard to know just where it ends.

I use the Dremmite drill along with the longer carbide burrs supplied by Deltakits for all my drill-stops. You should always drill up to at least the middle of the burr (sometimes just a little longer, depending on the length of the crack) to ensure proper depth. You'll typically feel a change in the vibrations just before you break through to the laminate. After that, I just leave the drill in the hole and give it a light tap with my hand for the perfect mini-bullseye every time.



Just be SURE to pull the drill straight out, and carefully. Otherwise you might end up with a broken bit inside the glass.

Nice illustrattion, something most trainers could probaly use. A you one anyway?

I agree w/ the Coitster, but for some reason Ford pickups were the only make/model that tried running past the bullseye.
