Finally, here it is: our photo tutorial on how to create your own dumpster chute. We did this last week; those of you coming over on Saturday will get to see it -- and fling things down it -- in person!
First things first: you've got to take out a window. This is the window at the top of our stairs; we built a scaffolding so that it can be accessed a little less precariously (pictures of the scaffolding are here and here).
Next, install a pulley above the window. If you don't know the physics of pulley-installation, I can't really help you. I was an English major. You'll note that we bolted a spare piece of lumber above the window for the pulley to be attached to so it would be even with the window.
Lean out the window to take pictures of the happenings below; get yelled at for endangering both expensive camera and self.
Buy approximately a metric buttload of sturdy trash cans (we cleaned out the supply at both Home Depot and Wal-Mart, which is why there are two different colors). Using a reciprocating saw or other useful implement of destruction, cut out the bottoms of all of the cans. (I had high hopes, but alas the bottoms do not work well as frisbees.)
Stack all your bottom-free cans together, and thread chain through the handles (one roll of chain per side turned out to be exactly enough). Make sure you've bought chain that is strong enough to handle the load; ours is rated for 300 pounds.
Make sure you've got a length of chain at the top of the cans to hang the whole shebang from; Don and his dad counted 60 links back and then looped the chain around the handles of the top can, using a bolt with washers and nut to secure it.
Tie or otherwise secure the other end of the pulley to the midpoint of your hanging-chains; make sure to leave the top section dangling free, as you'll bolt this to the window frame later.
Using the pulleys and some brute strength, maneuver the stack of cans upright.
Hoist the first can to your desired height; the bottom should overlap into the next can so nothing will fall out of the chute. Designate that useless person standing around taking pictures to hold the rope in place while you loop chain around the next set of handles and secure with bolts.
Do it again.
And again and again and again and again and again.
Once the top of your chute has reached the windowsill, run upstairs and bolt those chains into place so whoever your poor rope-holder is can let go. Then come back down and heave the end of the chute into the dumpster. We bolted the last few cans together still stacked, to provide a little stability and weight to keep the end securely in the dumpster.
Take a spare can and create a hood for the top of the chute. When you're not using it, you can just take the hood out and tarp over the window.
There are a few extra pictures in the set here.
