There is described a light, portable thicknessing machine for wood, which comprises a base part including a bed (1) over which wood to be thicknessed passes, and an upper housing (9) in which are mounted a cutter and feed rollers to advance the wood, the upper housing being slidingly supported on a number of pillars (4) extending upwardly from the base part (2). At least two oppositely disposed pillars (4) have mounted coaxially therein threaded shafts which engage with lugs fixed to upper housing (9), the lugs passing through longitudinal slots in the pillars (4). The threaded shafts are interconnected so that they rotate together, by means of sprockets at their lower ends engaging an endless chain (6) rotation of the shafts thus effecting vertical movement of the upper housing (9) to adjust the height of the cutter above the bed.
