Hey, I have a very interesting story for you guys.
Early on in my woodworking journeys, I done something really stupid that relates to this thread.
I had these drum sanding doo hickeys that were meant for the drill press.
One of them had a quarter inch shaft.
I had a quarter inch router in a router table.
The drill press at top speed done a pretty good job but I wanted to sand faster.
So I decided what could I hurt by putting the quarter inch drum sanding accessory into the router?

Let me stop right there and explain that somehow it did not occur to me that these drum sanding things were not exactly balanced and that this cheap router had on one speed, 30,000 RPMs.

It ran great for maybe half a second.
Then the top part of the unbalanced drum sanding thing started swinging further and further away from center.
By this time, the whole table and all was bucking too bad for me to catch the power switch.
I headed for the cord.
It was too late.
Parts of sandpaper had started flying off at shrappnel speed.
At this point all I could do was dive under a nearby table for safety and wait for the events to unfold.
The table (this was a HEAVY weighted table) started doing more than bucking. It was more like a jackhammer at this point.
Then it started whirling around about two inches off the floor like it was caught up in a tornado.
It would slam the floor every few seconds.
Th whole drum sander assembly broke off (later I learned it broke even with the chuck that holds the bit)
The router table was still violently dancing though.
Then something else broke off and flew the opposite direction (I later found out this was all of the router shaft that sticks out of the router housing)
The router then sounded like it sped up to about 100,000 RPMs.
Then the lights when out (later found out this was because the router motor housing had cracked open and shorted something out.)

So, ummmmmm, NO.
Never put a drum sanding attachment into a router.
I tested that theory and it doesn’t work out very well.
I ruined the router, the router table, the drum sanding attachment, the door that the drum sanding attachment flew through, and I swear I took at least two years off of my projected life span from the fear.
