Okay, so I just acquired a 10" Covington trim/slab saw that is set up for gravity feed. I read on another post that the poster used a paint can on a string and just added or subtracted rocks as needed. I'm new to this, so bear with me if this is a stupid question, but how do you figure out how heavy the pull needs to be?
I get the gist, harder stuff = less weight and lighter stuff = heavier weight but how specific does this have to be? Like i said, I have not started cutting yet...but getting ready!
Thanks in advance, Ash

not that specific. no more so that push harder for soft stuff when hand feeding and push lighter for really hard stuff.
if the rock is not advancing an inch in 5-8 minutes, you need more weight

thanks About how much weight would you usually start with? ~5, 10, 15lbs? Less? or just throw some in that bucket and see how it goes?

I've got the same saw. I like to run lighter. On a 2 1/2" thick piece of jasper ( mohs 7) I want it to progress an inch every 12 - 15 minutes. Extends blade life. 2 pounds will give me this rate.

Although sometimes messy if not careful...........sand is easily transferable and you can dial in the weight better than odd size rocks, steel pieces etc.

I picked up some salt-water fishing weights (one and two pounds). They work quite well.
