Thanks for the question and thanks for the idea that I should assemble a quick and dirty publication describing common Wood Product Logging Terms!
Bolt - any short-length log; usually less than 8-ft in length.
Tie log: logs that meet the minimum criteria for crossties, switch ties, or bridge ties; generally lower quality logs, yet all tie logs must be sound.
Pallet log: low quality logs that generally would not yield a significant proportion of grade lumber.
Stave: narrow sections of wood used to manufacture barrels or casks.
Stave logs: logs, typically white oak species, that meet desired specification for the manufacture of tight cooperage for use in the wine and spirits industry; used to manufacture stave bolts.
