Which chimney?

[PotsieWeber]

I thought about making one, but didn't because I picked up some Weber ones free, while acquiring grills.  Before that, I had a cheap one that was annoying me. 

Here is one version https://www.youtube.com/watch?v=YsthDqIXcwM

Place it on the grill grate when lighting & you'll get plenty of air.

As @YardBurner's  post suggested, you could just cut the top & bottom out.  Just put newspapers (or whatever) in the bottom and coals on that, tilt the can slightly to light the newspapers & eventually lift the can straight (maybe using some pliers, oven mitts, whatever).  You could even get somewhat fancy & make a handle or just drill a couple holes near the top you could temporarily hook)such as with a coat hanger & lift).
