I'll bet that smoker didn't last more than a half hour. Also after you have it going real well, put your hand over it and see how hot the smoke is when you puff it. You will probably find that before long you are shooting sparks into your bees.
If you have pine trees, pick up a large double handful of them.
Take a small amount of the needles, roll them up and light the end. Use your hive tool to push them into your smoker, lightly. Puff it until it is shooting flames out of the top of the open smoker.
Take another larger handful of needles and roll them up real tight and push them in the smoker with your hive tool (HT). Then while puffing it push it down tight with your HT. Do this again to pack it real tight.
Keep puffing while packing. Fill it full and close the lid. It will last for about 3 hours or more. At about 3 hours you will need to pack it tight again.
If you do not have pine, take a pare of old jeans and cut them into 1 foot squares. Light the end of one and put it in the smoker, puffing to get it blazing real well. Add more squares and fill it. With jeans, you have to be careful not to seal the smoke from going up through the material.
Even a small amount will last for hours with out puffing.
I use jeans because the smoke is much nicer on me than pine.
