Drill Holes

[mobilerockchiprepair]

I think I might not be letting it cure long enough. Because when I shave the pit resin and polish, the polish goes in the drill hole like I never put anything in it. Almost seems like the pit resin is too thick for the hole and when the injector is lifted off it is taking some of the resin with it. I am going to try curing under pressure a few times and see what happens.

Is there other techniques to try and remove the small black rings (trapped air) without having to drill? Whenever I do not drill its usually a choice between leaving these ugly black rings or the tiny drill hole. Also what is a good polish to help clear the drill hole?

mobilerockchiprepair,

To drill or not to drill! Well, we always try not to drill to provide the best cosmetic outcome in my opinion. We have found that by taking the time to do a few extra cycles(vaccum/pressure) in combination with a little massaging that most breaks will fill. You just have to be patient. There are some situations that do require drilling though...such as a star break with a disconnected leg. I feel in the end the most important aspect from a technicians point of view is structual and second would be cosmetic. With that said do what you feel most comfortable with to provide the best structural outcome. Hope this helps.

Pay it forward,

I use the drill on most repairs some to just clean the pit others to drill and pop. The one thing I make sure I do if drilling deeper is to make sure the opening of the hole is angled upwards from the bottom, you will struggle to pit fill it properly or with ease if the hole is horizontal or the opening is below the bottom. I have noticed many techs I have trained do not focus on the angle of the drill when using it. This is even more of a problem when working on flat screens or reaching upwards.

Wheather to drill or not should depend on the type of break you are repairing. I think a few techs are a little hesitant of drilling because of not being comfortable with this procedure. The more you do drill the easier it becomes. The purpose of drilling and tapping is to create more area for the resin to fill the break completely.Be sure to cure under pressure before you tab and cure the impact point. When you remove your injector to tab and cure make sure you have sufficient resin over the drill hole and try to ease your tab over the hole to prevent the tab from pulling resin out of the drill hole and creating a bubble. If you notice a small bubble remove your tab before you start to cure, take a sewing needel and work the bubble out, use a drop of resin and retab.

Question...

If the damage will accept resin why would you want to remove more material by drilling?

If time is the reason, then I would agree. It is easier to fill a break and quicker if you drill. I am still not sure on the appearance side of this though.

What our your thoughts?

Pay it forward,

oh no not the drill thingy again

When you guys say drill and tap, does that mean that you never drill all the way through the first layer of glass? I try not to drill but the times I have drilled through the first layer of glass the repair is much more visible. Lately if I have to drill I will drill 2/3 into the first layer of glass then tap my probe and create a small bullseye. The repair seems to come out cleaner than drilling all the way through the first layer of glass. Also, sometimes at different angles I can still see darker shades in the cracks. Is there anything I am doing wrong or is tht just the way some repairs turn out?

I went back to some of the earlier posts on drilling. Everyone says never drill all the way through the first layer of glass. So I get out my Delta training dvd and watch it again. The guy on the dvd drills all the way through the first layer. Whats up with that?

You should never have to drill that deep. So a demo show's it done that way, Don't do it just drill and pop the rest of the way and your results will be improved and the lami will remain intact!!!
