My guess is that Festool would/could probably introduce this technology
to their Kapex, maybe their planers... I doubt that they would want to
start making a Festool TS with this feature since they now own a company
that does make TS's. Festool seems, at least here, to focus on the
portable power tools. The TS is less portable with the exception of the
job site contractors saw.
I guess Festool could share technologies and maybe offer a better fence
other than the Beis clone. Something like the old Delta Unifence comes
to mind. Maybe not a wobble but perhaps an oscillating blade option for
dados.

I can't see much need at all on planer unless you're thinking of
handheld jobbers (which I guess is all Festool would have, anyway) so
maybe.

Yeah, the Festool hand held planer.



I think the biggest safety spot albeit not so much in use any more w/
the advent of the larger router is the spindle shaper (or the router
mounted as a shaper). There's a chunk of spinning steel that can do
some major damage in a hurry. I doubt it could meet the proposed CPSC
spec, but it could minimize the trauma otherwise.

I wonder if the shapers, and mostly because they spin at a relative low
RPM compared to a TS blade, if they could make an electromagnetic brake
much like cordless drills use.


Festool'll have to stay out of the equation on the TS from the EU
regulation standpoint or there will be no dado head of any type; EU
reg's prohibit them and I think enforce user compliance by not allowing
an arbor shaft long enough to mount one...

Yeah there is that. And I wonder what the issue with a dado blade is
with the EU regulation. But with that knowledge I think it is more
about stacking blades than cutting dado's. If the arbor oscillated like
a spindle sander does a single blade could be used.
As for as the EU is concerned I do not think a dado blade is the issue
as you can get dado blades that are fixed width. I really think it is
about the multiple stacked blades that is the issue. I think with so
many surfaces touching each other extra pressure is needed to prevent
the mass from coming loose on the arbor. More than a simple single
blade. I witnessed this once on my saw, I did not properly tighten the
dado set and it had enough mass and momentum that the stack continued to
spin well after the arbor stopped spinning. And on my right tilt saw it
could have loosened the nut enough to fall off.

Check out this Felder dado blade. Actually stacked but only two really
wide dado blades that engage on the arbor and two dowels that lock the
blades to prevent slipping between each blade.
