I use a 3/4" paddle bit in my drill and drill into the end of a split of whatever wood you want to have sawdust from.
Give it a whirl Mate, the sieve cost me a couple of quid!
To light it, I just hold it over a tealight candle for a minute or so then remove the tealight and let it smoulder.
I have found that draft is a big factor in using it....with the lower vents on the Excel20 open but the access doors shut I get ~5.5hrs out of it, with one of the access doors open I get about 3-4hrs (but it has been windy here).
Although in the summer I have seen it get up to 40 degrees celsius here! And it was about 95% humidity too. But that's a daily thing in the summer here in the south. Rough stuff, but I love it.
