Best Practices for ripping random width lumber and creating a good glue joint
Ripping of random width lumber to create part blanks and stave material for wood products has for many years been accomplished using straight-line (single blade) rip saws.
When production demands outgrow the capabilities of a single straight-line rip saw, manufacturers have two options: they can add more straight-line rip saws, with additional labor required, or upgrade to a gang rip saw.
Regardless of the type of saw, it is critical that the gang rip saw be in good condition and adjusted properly for successful glue joint production. Feed works must have a flat and true surface and the means for captivation - friction, spikes and knurling - must be suitable for proper material containment.
