this is true!! i cut my body out with a jigsaw, and it wasnt straight. its the internal curves that kill them. the blade binds on an internal curve, and heats up causing friction, then the blade becomes more susceptible to bending forces, and it tends to spiral inward. it didnt matter with my body, as there was sufficient wood to shape this out, it actually followed the shaping i wanted pretty well! use a coarser blade also, these cause less spiriling, since they can cut the wood easier. easier cutting means less friction = less heat = less spiriling.
D'oh... I wish I had read this the day before I cut my bodies yesterday. I used a jigsaw and I kept somewhat distance to the drawn body lines on the wood. But still, I noticed afterwards that several lines had been cut uneven - certainly not straight - and in some places I am not sure how to recover it.
Learning it the hard way I suppose
Do you guys think I can fix some of this up with woodfiller?
I'll keep at least 1/2" distance next time I jigsaw a body..

I haven't had any problems with using a jigsaw. You just have to get enough relief cuts in for the curves, really important around the horns.
