How would YOU fix this?

[GLASSTIME]

Wont let me go back and edit.

DryStar, this was your comment "If I find one where a leg is expanding and flexes open, I'll try to stop it."

[kingmonkey]

Why would you ever drill the centre of a bullseye, it is just a solid piece of cone shaped glass. Also why does it make any difference if the leg is sub or or not when doing a drill stop.

For me drill and stop the running leg at the end and fill from there, accept the blemish in the bullseye. This would only be for a low end vehicle or truck windshield. I would suggest the repair failed due to moisture or air being left in at the first attempt.

I know it wasn't moisture because I checked for moisture and found none, and dried it out anyway just to be sure. That's my standard practice. I "dry out" everything. I believe it was air left in the break. My concern was with the crack. I terminated the crack by popping a bullseye and filled from there. I couldn't really see what else I could do with bullseye, I just wanted to stop that crack. We'll see if it works. I told the guy that if that didn't get it I'd give him his money back. We'll see.

[screenman]

In that case you did the same as i would have done.

To explain why we would never drill a bullseye I would need to explain how the glass is displaced when it breaks. I would struggle to do this without drawing it, so I hope that in training everybody had this explained to them.

I agree with what I posted on the previous post, however I doubt you will find any where that I advocate drilling into the centre of a bullseye, I just asked for your reasoning behind this. Whilst I agree the forum is for helping out I feel it is important to give our reasons for doing a certain thing, often in our trade there is no reasoning behind why somebody does things a certain way other that they were shown it that way, what happens if they were shown by somebody who had also been shown the wrong way.

So the question I asked and will ask again for the benefit of the OP why drill the centre of a bullseye and why does it matter when drilling and popping if a leg is surface or subsurface.

For me the leg part makes no difference if the leg is long and running drill and pop it.

As for the bullseye the centre of the damage is only connected at the top or surface of the glass with the surrounding damage so drilling and popping will not give you any more access.

I apologise if my style of writing causes offense it is not meant to do any more than get further explanations.

I think it might be instructive to recognize when it's more appropriate to offer "opinion" and when it's more appropriate to offer "advice based on experience". Obviously the lines blur somewhat just as there are an infinite number of shades of gray between black and white. However, my perspective is that it is more appropriate to provide opinion when the topic is conceptual, theoretical or philosophical, and more appropriate to offer experienced-based advice when the topic is of a technical or procedural nature. As an example I would never reply to a post about networks, Safelite, or insurance companies since I have no experience with any of these. Any response I would post would be more conjecture (or opinion) than experience - and I would surely end up with a lot of egg on my tie, so to speak.

I assume that Kingmonkey was seeking experience-based advice. While it's certainly true that we all put our pants on one leg at a time, it's also true that opinions are like rear ends - everybody has one. What everybody doesn't have is the breadth and depth of experience requisite to dispense advice. To that end I have to agree with the advice offered by Frank EU, Screenman, and Drystar. I concur as well that drilling the center of a bullseye is a techique that should have been warned against in WSR school and taken to heart by the student.

Kingmonkey,

Sounds like you did everything right. My only other opinion which has been expressed by Screenman many times before is when you dry out a repair with heat, you'll find at times a leg or part of a bullseye will be stuck closed for whatever reason.(sometimes for 10 minutes or more) I've found this to occur in the past. Not sure if you use a Delta heat sink but it may help in the future to speed up the cooling process. If I know a leg was there and didn't reappear after heating many times I will flex it back open with my probe. Hope this makes sense to you and others.

WOW!

puka pau, Wouldn't it had been easier and less work on your fingers to just say all of that in 5 words or less?

Hmmmm. WHich I would say that is your "Opinon"


I don't claim to know everything there is to know about WSR. THus that being said I do however like to shed light on something if I too have been faced with the same. As to Why Drill the Centre of a Bullseye, well the only logical reason "I" would drill in this circumstance if I were to re-repair someone elses poor repair. You know, it's been cured, there is cured waxy resin there. In order to inject new resin and maybe get a little more air out. You would first have to open or attempt to open the cured repair opened.

I never asked nor made it known that no one on this forum follow my advice! And yes I have had the experiance and yes in my opinon that is what I would do. It's a choice, like the choice to hop on here and type your text. Screenman, your posts have never offended me in fact I find your posts very informational. I have to say this is got to be the first time I feel attacked here on the forum! (SEEMS ALOT OF THIS IS HAPPENING ALOT MORE FREQUENT)Makes you feel like a "Gold Medal" all I simply done was voiced my opinon in my own experiance.

I concur as well that drilling the center of a bullseye is a techique that should have been warned against in WSR school and taken to heart by the student.

I'd really appreciate it if you wouldn't talk down on my teachings that I received from Delta. I am factory trained and certifed! I don't take that lightly!

Have a wonderful day!
God Bless!

[screenman]

Did Delta teach you to drill the center of a bullseye, if they did I am sure they might have been trying to explain something different. Have a look at my other post about a bullseye and you will see why this is not required.

[screenman]

Do not worry about being attacked I have had it a lot of times, just goes with posting our thoughts on the net. I used to get worried about it now, well I suppose I still do, just got to keep smiling.

Glasstime,

I really don't believe anybody is talking down to you. You have to understand that your training with Delta is under perfect conditions and is provided in a controlled environment.(it's the basics where you start and then expand your technical knowledge) When you get out in the field things change and you'll have to adapt to that for your area of service. Your doing everything right so far, it just takes some time to make it better.

God Bless you too!

Kingmonkey;

At the risk of beating a dead horse, let me say just one more thing before this thread is hopefully euthanized:

You should stop that crack from spreading. Drill and pop the tip and fill it. Depending on the quality (surfaced or not) of the crack you may have to use more than one vacuum/pressure cycle to evacuate all the air. If you want the previously repaired damage to look pretty, drill into the void and fill it. If in fact you did properly dry out the original damage the void is likely just an air pocket. From your drawing, the drill hole should be one percent or way less of the total surface area of the void.

And Glasstime;

In five words or less: Don't drill bullseye centers

Cheers;

Puka Pau
