I use a Pelouze Model# PE5 digital postal scale I've had for many, many years. It is pretty beat up, but it keeps on working
I just weighed eleven pieces of CS hickory wood chunks. The weights were between 1.5 and 3.0 ounces.
Four pieces were between 1.5 and 1.9 oz, three pieces were between 2.0 and 2.5 oz, and the rest were between 2.6 and 3.0 oz.
Don't know if this helps you or not, but there you go.
Myself, I always weigh my wood when using my SM025. When using my other smoker (home made) I never weigh the wood I just know from experience how much is enough and how much is too much.
The CS makes such efficient use of wood smoke it really pays to weigh the wood. You could easily overdo the smoke, IMO.
