cut off saws/cutting bundled lumber to length

[woodduckhunter]

looking for ideas/ways to cut bundled lumber to length, cut off saws.  what do most people use?  Has anyone ever tried some sort of guide for a chainsaw?  what are some relatively reasonable saw/machine options out there for this?  thanks

The traditional way is the old double end trimmer. Some operators use a yard saw that is a chainsaw on wheels.
