Hi,
I seem to have a great many problems trying to cut a straight line with a jigsaw. It always wants to veer off line, the blade seems to bow. I find myself lifting the jigsaw's base off the timber to force it to cut along the pencil line but this doesn't give a satisfactory cut. It usually also ends up cutting on a downward angle that isn't at a right angle. I don't know if I need a higher end machine, because this has happended with 2 different jigsaws. Also I'm lefthanded and maybe jigsaws are designed to be cut by right hand (like most things in this world!!) Any tips welcome, cheers
