My wife has a 'shred bucket' ( a tall kitchen garbage can) that she throws receipts and such into. It's tucked out of sight so I never see it. I happened across it last week and saw it was full.
After 30 minutes, the shredder dies. It's over heated and the thermal protection circuit has tripped. I had to fasten computer case fans to the vents to air cool it, and take a 10 minute break after filling each 5 gallon plastic bag.
To make long story short... 3 hours to shred almost 3 years of reciepts, credit card solicitations and other such crap.
11 bags later....
By coincidence, our garbage company delivered a nice new 40 gallon recycling bin this week.
Thanks to this thread, that's where the last 4 bags will go, after transferring to paper bags.
