How to create a Crack with Wings and Repair it!

[robert n]

Does anyone know how I can create a windshield chip to look like a 1/2" crack with 2 wings...Small impact point, with no bullseye....you see these with the little wings when you view it at different angles and the 2 legs tapers to a tight cracks. I need to create these on my practice windshield and practice, practice, practice.

As for the repair. Should I drill at the impact point and pop a bullseye to open up the chip? or should I drill next to the impact point and then pop a bullseye to connect the new bullseye to the center of the wings?

I find a carbon tipped scribe or a tile cutter held against the glass and tapped with a small hammer will create this style of break, try with and without drilling and if you do drill the because they are small through the impact point works.

Screenman, can you please clarify..I don't understand

When filling try with and without drilling and if you do drill the because they are small through the impact point works.

Is that better?

When filling the crack with wings (batwing); first, try to fill it without drilling.
If it doesn't fill; then drill at the point of impact and pop a bullseye to open it up.

I would say after you have done a lot of batwing type repairs you will know which one's need drilling first, so I disagree slightly with Mr Bill, however if you do go down his path make sure you use a new bur when drilling after resin has been introduced, it is a fantastic lubricant. Also make sure no UV can get to the partly filled damage whilst you are drilling and popping, I know it only take a a minute or so but this can set the resin going off.
