Short answer: don't break the tubes. Don't even take these things apart.
Long answer:
CRT recycling is regulated at the federal level and by many state governments.
In many states, dismantling CRTs for scrap is illegal unless you have a specially licensed facility. This is because of the hazards involved, mainly:
1) the risk of electric shock (capacitor discharge)
2) risk of the tube imploding
3) disposal of the glass tubes, which are hazardous waste
The glass in CRTs contains lead, and many computer monitor tubes also have barium in them. When one of these tubes breaks, it emits a cloud of contaminated glass dust into the air. This is not something you or anyone else should be breathing in.
While the front screen portion of a tube is very resistant to cracking, the rear portion normally housed inside the device is surprisingly fragile, and pulling or pushing on a component near the neck can suddenly pop the whole tube. Some televisions also have the yoke glued to the neck with epoxy, so they are impossible to remove safely without heat.
With all the ways to make money scrapping, I would recommend avoiding CRTs. When you factor in the regulations, hazards, labor, and small amount of metal produced versus the large amount of trash they are not worth it to the small time scrapper. Companies that make money recycling them legally are doing high volume and getting recycling credits from the manufacturers. The refurbish/resale market for most CRTs is nearly dead.
There have been several posts here regarding "tricks" for dealing with CRTs. One was to charge a small processing or recycling fee per unit to the customer and then take them to Best Buy for recycling, pay $10 each to recycle them and in return receive a $10 gift card.
