Trion jigsaw blade deflection

James.

All above replies are correct; the guides are set too tight. Adjusting them properly as Tom mentioned with the Steve Bace technique is simple, quick and foolproof. Just to mention that technique is also important; use the correct blade and don't push the blade too fast.

Is the blade exhibiting any sort of physical deformation other than the bending?  I'm trying to figure out my blade deformation issue.

I'm not sure of the brand right now. I'll have to check. They don't get black but seem to leave a groove in the side of the blade but even if I loosen it more it doesn't help unless I loosen it a lot. I would only be cutting mdf or chipboard when I'm fitting shops, kitchens etc.

@galwaydude18
Just out of curiosity, are your carbide blade guides parallel, or is the guide on the scraped side at a slight (visible) angle when looking at the unit head on?  For example, in my setup the right guide is toe-in at the bottom, a la: ||/ .  I've just noticed my (new) unit starting to do this and am puzzled.

I'm pretty sure the above discoloration rings and black area are to what Shane is referring in an over-heated blade. :-(

How do I know if the carbide blade guides are parallel or toe in?

When I look at the front of my Trion (more easily visible without the blade), the left (looking head-on) guide appears almost nearly vertical, and the right guide appears closer at the bottom, like this: | /  .  So, when some side force is applied by hand or the blade attempting not to remain vertical/ straight, the right guide only supports the blade along its bottom edge (or a single point), instead of across its whole face.  Nigel made a good point about the whole guide assembly being centered, and I have tried to adjust this assembly, but I'm not sure I have made much progress, as the adjustable side of the guide is the one that opens up when making adjustments...resulting in a gap I can slide a piece of paper into one the blade freely slips in when doing the guide adjustment either way (blade starts in or outside the guide).  I tried to get a good picture, but the one below is the best I could do...it's not too clear, but does show the guides are not in-line vertically, either.

Incidentally, when I first received my Trion and was looking it over, I noticed the "non-parallelness" of the guide blocks and checked with Festool's support about it.  The gentleman said it would/ should be okay.  I have tried both guide adjustment methods and tested for a gap with a piece of paper, but with my third blade now shaved on one side, I am skeptical it does not need some attention beyond what I can provide.

Difficult to tell what's going on but looks like you might have to send it in to TTS.
