you will need:
a band saw
and some fire wood
if you like my instructable vote for it in the contests!
of you have any other instructable ideas you would like to see i will do my best!
first joint your fire wood so it has 2 flat sides that are at a 90 degree angle.
make sure your band saw has a nice long fence and set your saw to your desired measurement plus some extra. this will give you something to plane off for a smooth surface. a deep/wide blade is recommended.
take your time and keep your wood square and flush to your bed and fence.
then cut off the unwanted bark portion.
you can also do this on a table saw if available.
now run it through your planer on each side and you'll have a beautiful piece of usable wood for your projects!
