Pop a Bull\'s eye

[GlasWeldTech]

If they didn't teach you how to pop a bulls eye-You need to go back and get your money back. Never heard of 6 hours of training? If you can't pop a bulls eye do not repair any cracks. I had 3 days of training and then after that I practised on practice glass for a couple of months before going out and repairing friends glass. Screenman is giving you and others some good advice here. It is like asking someone if they like ford or chevy if you drive a ford and they say chevy-you didn't like his answer. They should have shown you how to make bulls eyes and stars and also cracks so you could practise. What did they use to train you on-repairs already made? In my training we broke glass and then we repaired it.

Like I said before, I was shown how to repair a bullseye, combo star and cracks. I took the training in April and have practiced on an old windshield in my garage for a couple months. I have only repaired two paying customer's windshields so far. It's a far cry from making a repair on a windshield in my garage to repairing a paying customer's windshield.

Yumsbpa,
If you look at espritws.com on their technical support site concerning long crack repairs. There is some good advice(with pictures) on "popping a bullseye". Hope it helps you.

Please for the sake of anyone wanting to get into screen repair tell us who trained you so that everyone can stay away from them.

The ability to drill and pop a bullseye is very important in this trade, although there is no need to do so on a bullseye.

Try tapping the centre of your partly filled repair it might give way and let you fill from the centre again. Personaly I would more than likely burn it out, but would not recommend this to a newbie. Drill and pop edge as a last resort. Hope this was on a practise screen and not a customers.

Question :
Would you please go into detail how you burn it out , thanks Ed

Screenman,

I would like to learn this technique you post of for previously repaired chips "Burning it out". I always have room for more techniques. Would you please share. Thanks.

YUMSBPA ... I do understand your query ... like you ... I was trained by GT too in Durango ... they NEVER taught me how to "pop a bullseye"!

I personally learned it from this forum, thanks to all that contributed. Stick around here long enough and try going through as many old threads as you can, its worth your time! .... you'll learn a lot more than the training that you've had. Cheers!

The frase ,popping a bullseye means drill a hole in the first layer of glass 1/2 way insert your scribe ,tap it softly,the bullseye will popup . This is done a little further than where the crack ends.
Fill it with resin after you placed the bridge and due to the pressure the crack will creep up to the created bullseye.Or push with your thumb on the inside of the windshield to make it run.
No aggravation would have been on this tread, if the question was answered correctly. Lets stay gentlemen !

Cazador, you will notice on my second post on this subject I described how to pop a bullseye, in the first post I suggested how I would carry out the repair. Please for my education let me know how I should have replied. As for burning out I just clean out the old pit fill with my drill and hit the centre spot hard with my blow torch. Without practise I would suggest nobody uses this method, or at least tell the customer what could happen etc. The only time I redo damage other people have repaired is for dealer's who's only other option would be to replace the screen I do not do them for retail. Hoefuuly one day training standards will be such that there will not be jobs to redo. Although I doubt it.

When your applying pressure to take the crack into the bullseye, make sure you are pressing behind the lead point of the crack ( usually about 1/2 inch ). By this I mean, point of pressure - lead point of crack - bullseye. Before you drill the pilot hole for the bullseye. look very closely at exactly where the crack has reached. Sometimes the last portion of the crack is virtually invisible and you will only find this out when you commence drilling and the crack runs straight past it. Gentle flexing of the crack from the inside of the glass should show the end of it, and I mean VERY GENTLE.
