Need a little info

[zlm_us]

Sorry for the double post.
I found me a practice shield and I have tried differant approaches with differant types of chips. I have a few questions if someone has the time to answer for me. Thanks in advance
1. What is the most common type of chip?
2. When I repair larger bullseyes and starbreaks (around a quarter or bigger) on my practice shield I notice that my chip always has small cracks toward the impact point no matter what I do they always exist. I am using GT Hot Shot. What would cause this? I have no problems with half moon, batwing, and small bullseye with no problems.

It is my experience that Stars and Bullseye's are the most common type of break that I run into in the field.

You said that you are wondering about the small cracks near the impact point in a bullseye or star break...

Basically, if the cracks (within the body of the break) does not fill, then it's going to look like an inferrior patch-job. You won't be happy with it, and your customer may not be happy with it.

You may need to open those cracks up so they will accept resin. One way is to drill and "pop a mini". This should open up the cracks within the body of the break so they can accept resin. It is actually a rare case when I need to go to that extreme, but it works.

Hope this helps.

(zlm us)my chip always has small cracks toward the impact point no matter what I do they always exist.


I have been doing alot of practice and Im using the rubber band with a weight in the middle. I think its from hitting it so hard the impact of weight is causing it to create the shatter toward the impact point. Now when I go to repair these all the legs are filling but you can still see them up close due to the hard impact which created the shatter effect, for me its like 15 small legs then i get larger ones that break out and sometimes a bullseye with it (i think), but they look like hairline cracks after i have filled and cured them instead of cracks which are not filled.

Like I said Im just getting started myself so if anyone has any more input to my post let us know.
Good luck

Actually I have experienced these types of breaks on practice windshields too.
Its difficult to get exactly the same type of break as you most often would run into out in the field.

In real-life, its typically a rock that causes the "rock-chip", not a piece of hardend steel from a tool.

Try using different materials to create a real-life break in the glass. Try holding the blade of a large screwdriver and striking the glass with the plastic end of the handle. You usually have to hit pretty darn hard to make a break. (Be sure to wear safety glasses or goggles).

When all else fails, grab a handfull of gravel and throw it hard at the glass. I haven't actually tried that, but hey, it might work???

If throwing the rocks doesn't work...try a sling-shot...lol

Zim, brad, It sound's like you are having a bull that is cracked on the inner side(pvb side) probably as a result of hitting the glass very hard and the dome of glass (bull) cracks inward.you need to expose any the crack's in order to fill them try as sneck said to drill and pop a mini on those.

Please tell us all where you were trained so that nobody else makes the same mistake.

[zlm_us]

not sure what you are talking about screenman, but I have not taken any training yet. I am scheduled for training this month. I believe the better I can do basic chips the more I can learn at training.

[screenman]

Great to hear you are getting training I would suggest that you wait for that day and practise afterwards so as not to pick up any bad habits before you start.

This business is full with badly trained people that call themselves experts, a lot of the kit suppliers offer very poor training ( not all ) Most of the trainers in the Uk do not even teach or talk about dryout thats how bad things are.

I just assumed because you had purchased a kit that you had already recieved some training.

Good luck for the future and become one of the good techs not one of the hackers.

Screenman I have found a new practice shield that had some actual rockchips and not made by me. I have two links below for pictures of the rockchips. Can you look at both pics and tell me how you would approach both chips. I am scheduled for training in Durango in two weeks, but I just cant quit practicing.
Thanks
