OT:tempered glass vs 12 gauge/ 9mm..

All,

I have a basketball backboard with a rotten frame, rotten pole, but good tempered glass. So far I've recycled what I can, but the backboard is too large to fit in the recycle bin.

This is not a professional backboard, just a youngster type board you could buy anywhere, but cannot give it away.

Here' my thinking, encase it in two large yard waste plastic bags, put a few round through it to make it into tiny pieces.

So, let's hear it, slug, or cartridge?

Saw on TV the other day (so it has to be true!) that throwing a broken spark plug insulator at tempered glass will shatter it!

Be interesting to see if it worked...
 
pointier the better. I've got spring loaded awl for the electric car windows. Just in case I drive into a lake.
 
im going with the 12ga and a deer slug. if yer gonna break it, may as well have some adventure!!
 
Markct,

I tried the hammer before on a double paned sidelight window. I was surprised that I nor a friend could break it with a hammer. We had a three pound sledge, with the window lying flat on a concrete floor.

Perhaps he and I should attend the gym more often?!

Your problem was you had it flat on the floor. If you had it up on a 2X4 or other such thing it would have been likely to shatter
 
Needs a point, corner of a claw hammer, point of chipping hammer etc and a light tap will pop it, oven a swiftly swung ice pick
 
Mythbusters put it plainly . They used an automatic centre punch , the spring loaded type to shatter car windows .
I followed their example to break some tempered glass kitchen splash backs that were too long to carry . Wrapped in an old sheet to collect the debris and shattered with one flick of the punch . This turned four lengths of glass into a shopping bag full of shrapnel .
 
Steve,

I've got plenty of old sparkplugs. I'll try to get a part of the ceramic and try to bust his pane.

I am doubtful. Hammers and energy had little effect. What's so special of spark plug ceramic?

Evidently it's harder than the glass... Think it would also depend on how it strikes the glass, it needs to hit with a broken edge to concentrate the energy in one spot.

Interesting to see if it works!
 
I worked for Chevy back in the 70's and would scrap the warranty windows. You could not break them with a direct blow of a hammer, but just a light tap on the edge and they would go off like a bomb. GM made sure we destroyed every part that they covered under warranty. Made for a change of pace to spend hours smashing up almost new parts.
 
The scum bag I caught inside my truck had a pocket full of broken spark plug porcelain, lucky for me I left the door unlocked since he was ready to break glass. I've heard of people using an automatic center punch or steel ball bearings too. Thieves like tinted windows, makes less noise and little mess, they can just fold or roll the broken glass out of the way.

Anyway, use something sharp and hard, if you want to stay back or have low noise try a bb or pellet gun. Run a couple strips of tape across the span of glass to keep it mostly intact for less mess.
 
U missed out on all the fun destroying stuff at the stealership before the airbag era!

Why not? How many of you have a Potassium Nitrate fertilizer and diesel fuel?
 

I made nitro glycerin as a 16 year old , [u:f24a24db15]worked a little too well [/u:f24a24db15] . Nothing on earth would make me repeat that boyhood folly !
 
Hitting it in the middle won't break it. Hit it near the edge with center punch or hammer and screw driver, it break into small pieces. Won't work on the windshield because it is laminated not tempered.
 
If it's just tempered glass that would work. I bet it's laminated too so the glass and shape of the thing would stay there. You wouldn't have to waste a round to find out, a hammer would do just as well.
 
I can vouch for how easy it can break from the edge. I was removing the hitch cover from a nearly new 86 series tractor. I had not open the read window and when the gasket came loose the popped up and the cherry picker arm hit the edge of the glass. It just exploded with tiny pieces going everywhere.
