I was watching the show tonight and was wondering where I can find the chainsaw sharpener that Tim showed Roger how to use.
A jig or sharpener does make it easier, but all you really need to sharpen a chainsaw is a chainsaw file (cheap!) that's the right size, a steady hand, and a little bit of instruction. I'm sure there are plenty of YouTube videos on the subject.
(I don't have a TV, so I didn't watch the episode.)
A chainsaw (or chain saw) is a portable mechanical saw, *****ed by electricity, compressed air, hydraulic *****, or most commonly a two-stroke engine. It is used in activities such as tree felling, limbing, bucking, pruning, by tree surgeons to fell trees and remove branches and foliage, to fell snags and assist in cutting firebreaks in wildland fire suppression, and to harvest firewood. Chainsaws with specially designed bar and chain combinations have been developed as tools for use in chainsaw art. Spe******t chainsaws are used for cutting concrete.
