My parents source of income is mainly cutting woods and lumbers. They own some kind of equipments to cut them and sometimes these equipments are a lot of a trouble instead of making money. Most of the times, the money they're earning went to the shop for the repairs and all that parts that they need in order to get the equipment running. I sometimes heard them discussing about band saw blades which back then i don't have a clue of what that is. So today i thought, the next time i talk to them, i might have ask them about the sizes of the blades they're needing so i can buy some of it to help them somehow.
