I found that Butcher and Packer company sells hickory sawdust for 5.25 for 5 pounds plus shipping. I ordered the 5 pounds and when I received it, took it and ran it through an old blender on the chop and or blend cycle to get the right powder like consistency to burn in my amazn sawdust smoker.It took me about an hour to chop/blend through the 5 pounds. I think you can find old blenders at any resale shop these days. The sawdust that you get from butcher and packer is not as fine as the sawdust that amazn smoker company sells, but will work when chopped/blend in the blender.I also found that by using a combination of 1/3 cup wood pellets
or less ( too much smoke), with your choice of wood chips, that my smoker will smoke like crazy and maintain a 165 degree temp. for smoking for about 1.5-2hrs. I did get the retrofit chip tray from
masterbuilt, which is larger and sits lower on the heating element.........this took care of the non-smoking issues that my smoker previously had. I am not recommending that you or anyone reading this post use wood pellets in your
masterbuilt smoker or use a blender on sawdust, just something that I do at my own risk. If you do not have the retrofit chip tray, call
masterbuilt, you will not regret it.
