UPDATE...
Ran to HD and grabbed a u-bolt, attached it to one end of the 6" tube, used my Victorio grinder to break up the pellets (had to loosen it up a bit, but I finally found the sweet spot), tapped the end of the tube on the table after every hand-full of dust, lit it up...PERFECT!
After the "coal" got going good and stabilized, the smoke produced was no where NEARLY as thick and white as before and the 6" tube lasted in the neighborhood of 3.5 - 4 hours (closer to 3.5 IIRC) without ever having gone out.
Happy camper here! Just though I'd let you know.
THANK YOU ALL!!!
Excellent!
Now to start experimenting with different flavors and brands of pellets.
