I`ve been having trouble with my band saw of late,thought it was knackered,wouldn`t cut kept going slow,changed to a bigger blade yesterday to do straight line cutting,found the problem,I put the blunt blade back on instead of the new one last time,luckely still have the new one in the bag as hadn`t got round to dumping it yet,so for circles,still have a sharp smaller blade phew,cheers,
Eric.
