pretty easy the yellow dewalt drill was only used to clean out the pellet maker, the pellets where made with a larger drill.
you have to add some oil to the grass to give it a some thing to bind with (like glue) i used left over kitchen fats. the pellets burned great but they did not stay together very well, after a week of dry time they got bridle but still burned great and a lot slower than wood. the temperatures compared with a the temperatures of a woodflame.
