I’ve used the “poor man’s Lieberman” a WLT bag from a lb of tobacco, duct taped on the back of one of my rolling boards. It works ok, but can cause clogs if using straight short filler or scrap filler from other blends. It definitely helps with shaping a cigar, but have found more enjoyment out of rolling filler entubado style and using a mold or paper strips to help form the initial body of the cigar. Air flow with the entubado style greatly helps with the airflow and burn, as long as you don’t cinch or bend the entubado filler tubes as you bind them up. If it was me in your position I would spend the money on extra leaf to blend with. That way he can learn rolling a way that works for him. Going through WLT and getting at least 1 lb in a vacuum seal bag and using that bag as a “poor man’s Lieberman machine” by duct tapping one on me to the back of a cutting board does the same thing as a Lieberman. Working the tobacco in your hands before trying out other methods, greatly increased my knowledge in creating more enjoyable cigars with good airflow, over trying to go straight to the Lieberman. Just my 2 cents worth. There’s no quick shortcuts with rolling “good” cigars. Please no matter what, tell him about this forum and all of us here will help him along the way.
