Thanks for the replies.
I have some very coarse Redgum sawdust that I am trying to use in an Amaze-N Smoker. I can get it lit quite easily with a strong, burning ember at one end, but keeping it smouldering continuously....doesn't happen.
At the moment I have a pile of it spread out on a tray in the oven on a very low setting with the fan on, so I'm hoping that will help. In regards to newspaper not being suitable - my regular butcher uses shredded and scrunched up pieces of newspaper, mixed with coarse Redgum sawdust in his smokehouse to make ham and bacon. Has done for years. And it tastes delicious. As I said, I can get this sawdust well lit with a butane torch, but it will only continue smouldering for a while before it goes out. I'm thinking the main problem is the sawdust isn't dry enough. The newspaper pellets I am referring to are completely chemical and additive free, biodegradable, and environmentally friendly, so I was thinking they mustn't be any different to regular newspaper when burnt, which doesn't cause a problem.
If there are any suggestions people can make, in regards to using this sawdust with an Amaze-N smoker, I'm all ears.
