Jig saw Sparks

[Drich]

I was watching a Video by The Wood Whisper and at time 6:30 I think its sparks are flying. What up with that?

Probably pushed the blade against the guide with too much lateral pressure.

The banned Netherlands video also had sparks, and some thermal imaging also showed that the blades can be at a high temp. But people still like the saw.

Well this is interesting. When I bought my Bosch 160 jigsaw I tried the Carvex too to decide which one I was going to buy. I could have sworn I saw a few sparks but the sales guy said it was just an optical illusion of the fancy pulsing light reflecting against the shiny new Bosch blade I took with me to do an apples to apples test.

Bring a CD with you next time:

It actually takes a brain and skill to setup the guides on a Festool jigsaw, that's how you achieve the accuracy of cut. Friction with metal against metal has the possibility of creating sparks.  Its the same thing that can and does happen when you setup a new bandsaw blade. That video that is referred too was the biggest laugh I had at the time and was made for the average intelligence of most nations, which I believe is that of a 12 year old. I place that video and videos of that moron that takes good tools apart and then criticizes them based on his limited understanding in the same category. Garbage for internet entertainment only.

As a side note to John's post. When I first started out as a Building Inspector I found out quite quickly that the any intercourse with the general public needs to be at a 3rd grade reading and understanding level.  None the less to say my first few correspondences when way over the heads of the recipients.

The blade is not sqaure to the base. Following a guide over a distance the blade slowly starts to drift causing it to push hard against the blade guides causing sparks. The blade will keep on drifting if you kept cutting and the blade starts to bend on the underside causing your face cut going out of sqaure.

Going free hand allows you to swing the jigsaw round as soon as you see it move from the line.

I dont think any jigsaw run well along a straight edge and wouldnt really recommend it for that type of work.  Many factors can cause the blade to drift. One being the base not sqaure to the blade.  Timber thickness and type and if you are going to cut with the grain.

Blade quality and blade wear. Thickness of blade.  If you use a blade you have already used for other jobs you could have made one edge slightly more blunt.

The saw in the vid is the Trion, not the Carvex.

I briefly had a Trion, was not impressed enough to swap it for the Metabo I already owned. Funny thing, selling the Metabo would have netted me €50 while I sold the Trion for 175, and I think my Metabo was slightly better.

As for straight cuts, I don't trust any jigsaw. All their blades wander.  Want it straight, get a plunge saw or a router.

Yeah, JMBfestool is correct.  A jigsaw should only be run against a straight edge in very thin material.

That woodwhisperer video show the wandering blade being forced up against the guide.

I've never seen a spark come from either my carvex, or my triton.
