Problem Statement
Design and build a mill that will auto-matically cut junk slabs to standard firewood lengths.
![Page 3: Slab Mill Rollin Bicskei and Travis Haley. Problem Statement Design and build a mill that will auto- matically cut junk slabs to standard firewood lengths](https://reader036.vdocuments.site/reader036/viewer/2022062421/56649d365503460f94a0dbab/html5/thumbnails/3.jpg)
Background
• After the client is done processing logs in to lumber there are leftover slabs unfit for standard use.
• Instead of wasting the wood it can be processed in to firewood.

Specifications
• PTO shaft driven, 550rpm, 34hp• Hydraulically powered drive units• 12-24” cuts off of 16’ slabs• Maximum width of slabs 20”• Manually loaded slabs• Portable, most likely on a trailer
