Making damage for practice.

Ok, I really hate to ask a stupid question but what are some of the techniques that you guys use to create different damage (cracks, stars, bulleyes) for practice. I tried a "BB" and a rubberband and shot the "BB" at the glass and that worked really well and creating a combo. Also, how much glass do you remove with the cribe. I practiced the other day on my old jeep cherokee and I scribbed a BIG ole pit in the glass as if I drilled with the dremel. Is that to much or is that right? The repair looks great on the out side (almost invisible except for the fact that I forgot to get the air bubble out of the pit filler when I applied it) but looks kinda bad from the inside. You can see a "ring" on the glass where the actual bullseye filled and can still see the many little legs that come off of it. Is this normal or a bad repair? I'm totally new and this was my second practice. Think I'm gonna start taking "Befor & After" pics of my practice repairs. Thanks to anyone that can help!!

Actualy I prefer the wrecking yard to making breaks in a practice glass. In the wrecking yard you see real world breaks and have to fix the as you would with the glass attached to a car. Just better practice if you ask me. There arnt many yards that would say no to you fixxin the windshields so they might be able to sell em ive never had one say no." Mr Wreckin yard dude may i practice on your glass I may be able to fix some well enough that they are useable for sale and the one I cant were already broken what do you have to lose?"plus ile fix any you have on your own car

A center punch works great for making star breaks.
The ring you see on the glass after your repair could be what I have heard of as the daisy affect. It happens when you apply too much pressure to a break.
If you want a piece of glass you can stick in your living room so you can practice while watching tv...that's what I do...just go to a replacement shop, ask them for a window they have already pulled. Go to a bigger place where they might have a few installs going at once. I can't imagine someone saying no. Ok, I guess I can imagine it, but I think most people will be nice.
Good luck!

Good advice on going to the junkyard, get yourself a damaged wind shield from a replacement shop and set it up at home. Use a spring loaded center punch and the bb breaker and go to it. You will make some tough breaks to fight your way through, If you can afford training by all means do it. I havent and learned on my own this is the hard road to take and you will need to give alot of time. Can be done if you are not in a hurry to start making money.

DO NOT listen to GlassStarz on using frozen chickens!! You must thaw it out first and toss it hard on your windshield. 
You sound like what i did on my repairs. I think you can drill the hole again and add the pit resin to get rid of the bubble. Correct me if I'm wrong veterans. As for the ring, I'm getting really frustrated on the rings myself but I'm still practicing some techniques to try to get rid of it. So far my rings are getting less by using little pressure, but when I used less pressure or cure without pressure, some of the resin would leave the bullseye and I could see air in it after curing.
As for creating the damages, I use the hook tool. Hit it hard, and it'll create a bullseye. Hit it a little harder and it'll create a combo. Hit it too hard and it'll create the most ugliest combo bullseye you'll ever see with legs running about 8" in all directions and cracks created on both the front and back glass (actually happened to me
).
If you need a practice glass, just go out and ask the glass shops. I told them I need a glass for a project and they gave me a nice 2x8 ft laminated glass for free.
