Question about drilling

[kingmonkey]

Hello, my name is Mitchell and I'm new to this forum.

I'm going to start repairing windshields tomorrow actually. I've spent the last month or so working at home on practice shields and working with the guy that is training me. But after reading some post on this message board I'm starting to question his methods.

He drills every repair but from what I understand you don't need to do that, correct? All of his repairs look really good, all the legs are gone from star breaks, everything looks fine. So is there any real disadvantage to drilling over other methods? Or is it just an older technique that has gone out of style?

Thanks!

Welcome to the forum Mitchell!

I have seen some systems that are not capable of filling the break properly without drilling, so I think the decision to drill is partially determined by the type of equipment you use. Using a Delta Kits system and recommended methods it is rarely necessary to drill, and cosmetically there is no way to make a drill hole look as good a a pit that has not been drilled, so we never recommend drilling except when there is no surface chip (pit area) present, or at the end of a long crack.

Yep, I agree with Brent. If you take the time on pressure and vacume cycles he results can be amazing. With only minor imperfection left compared to a drill hole. I only use drilling as a last resort.

Excuse me, I mean Vacuum not vacume

I've got a cheap home-made bridge made out of thick Plexiglas right now. It does the job so long as I drill first. As soon as I get some money I'm going to buy two of the Delta Kits bridges and injectors. The guy that is training me uses some other brand, I can't remember which, but I didn't have the money for a new bridge so I built my own after looking at some designs online. Works good enough but I'll be getting some Delta Kits equipment soon!

In my sermons at the church of the holy WR I always preach
"Beware the call of the evil drill it will lure you and try to lead you away from the life of the pure repair! be strong drill not!"
That said I drill one in 20 its easy to drill each one the final repair just wont be as good
Feel free to send donations to the Church LOL

I use the drill on most repair's but not to drill into the damage. I use it as a powered scribe I find this more accurate and does a better job than the normal carbide tipped hand held scribe. I add again I do not actually drill into the damage unless required.

I try not to drill in most cases, as well. But that brings a question to mind.

Obviously, there is the very occasional break that needs the assistance of being drilled in order to fill.

However if you did not drill and the break is not filling properly even though you have tried every technique, isn't it now too late to drill?

Wouldn't drilling into an impact that you have already introduced resin to be a problem?

Amen brotha!

To drill or not to drill
That is your choice
