Handy chopper

Portable power sawmills with small
engines have been developed by an
Australian company. The sawmill,
weighing 325 kg, takes only five
minutes to reset and can be dismantled into five pieces and carried in
the rear of a small vehicle. Made of
high tensile steel and galvanised
components, the sawmill can work
on felled timber right on the spot
where it falls, thereby saving time,
energy and humanpower required
to haul the timber to the sawmill
site. The sawmill can cut through
logs of 6.2 m length and 1.5 m diameter into 40-cm-wide boards with
the help of a circular blade, which
can rotate through 180 degrees.
