Is there a Flex Shaft accessory for Standard Routers?
mkochsch
on a standard router which will turn my router into a dremel-like tool with
a flex shaft?

None that I know of and if there is, I don't want to be near it. That shaft
would be turning at 24,000 rpm. Not a good idea for things of that size.
Can you imagine an abrasive wheel that it could turn with that power and
speed?

Dremel's are not 2 or 3HP though :)

But a Dremel does not have the power to sling an 8" grinding wheel. Look at
the RPM ratings on larger grinders, saw blades etc. The max will be 4 to
5,000 rpm.

20,000 rpm for the fastest Foredoms. Those are a properly mounted
motor too.
Dremels (puny little pieces of crap) only spin at 30,000 rpm when
they're spinning freely. They also only claim 20,000 for the
flex-shaft versions. If you actually try it, you're lucky to reach
15,000.
Most of the sub-Dremels with optional shafts recommend a maximum of
5,000 when using a flex shaft.
I'd use a router to drive a flex shaft (it's just a motor after all)
but I'd want some serious engineering of the shaft mount, and a
Foredom-like swivel to suspend the motor. Just shoving the inner core
into a collet and resting the motor on the bench is asking to get
hurt.
If you _really_ need an ultra high speed tool with a tiny handpiece,
buy some second-hand dentistry and get an air drill.

of ways for securing the motor that come to mind (side mounted router table
for instance). The HP and RPM's don't really play a factor, it's the
anchoring of the motor, I could make a lathe out of a PTO from a tractor if
I could hook it up easily. I figured I'd have to dial the router down to
lower RPM. I'm just amazed something like this isn't out there.

Many farm machines have a V-belt pulley driven from the PTO shaft. I
think a rotery mower might be the easiest to adapt.
Looking forward to seeing the pictures . . . ;-)

Let's not get too antsy. At one point, a good number of consumer radial arm
saws were available with a power take-off, and, IMS, several had flexible
shafts to fit. I never used one, but there we're also talking about 1-1/2 HP
(probably a lot closer to true HP than the so-called 3 HP routers we see
today), though shaft speed was MUCH slower.
Some attachments that allowed use of router bits were also available. A lot of
this stuff must still be around in varous places.

I'm certainly one to adapt things where possible, but using anything at router
speed that wan't specifically made for it is something I stay away from.
I was in a woodworking tool store once when a customer came in to complain
about the quality of their drum sanders. The small ones, with a 1/4" shaft and
maybe a 1.5" x 1.5" rubber drum, designed for use in a drill press.
You guessed it. Router. Bent the shank to 90 degrees, and how he managed to
hang on to the router I'll never know. It must have been bucking something
fierce. He never really did understand that he'd done something dangerous.
Actually, the Dremel probably does have the power to sling an 8" wheel. Might
take it a minute to get up to speed, though.

that the horsepower behind a router would make a flex shaft pretty
dangerous.

It's not the horse power that would bother me. We all know how these
horse power ratings go.
What would worry me is the spinning mass of the armature. That old
inertia thing. Get a half inch HoleShooter and drill a hole where the
bit binds. I'll bet this has broken more than one wrist. Get a similar
rated air drill, bind it's bit. By comparison it's a nuisance.
I could see a grinder on the end of router driven flex shaft binding,
the shaft pretzeling and getting shorter pulling drive and driven
closer, the router inertia trying to keep everything spinning, if the
motor slows the rotor making torque ..... Yee Haw. Your along for the ride.

Maybe a linear grinder?
(see:https://www.google.com/search?q=linear+grinder&oq=linear+grinde )
Or a trimmer (e.g. https://www.youtube.com/watch?v=nrS-uIZV9z8)?

The OP rigged up the flexible shaft from his Dremel so that he could use it with
his 3HP router. Things were going fine until the internal cable bound up, kinking
the casing and whipping the router up into the air and into the OP's head.
They say that he is doing OK, considering. He spends his days yelling at re-runs
of The New Yankee Workshop while the nurses wipe the spittle from his chin.
He gets especially worked up when Norm opens that drawer full of routers. Something
about "They are trying to kill you!" but it's kind of hard to understand him.
