After seeing a build by Stefan Gotteswinter on his channel I blatantly stole some of his design and built a carbide hone.
Sorry no photos of the build, my camera phone died.
Recycled a small 1800 rpm motor from the tilting mechanism in a hospital bed. Cut away the gearbox and matted a pulley to the 1/4 gear it had for a shaft. The disk spins at 500 rpm, speed stollen from Accu-Finish.
The disks came from China via Aliexpress 800,1000 and 2000 grit at about $1.50 each plus shipping.
The aluminum backing plate has a centering hub, two drive pins and two magnets to secure the disks. Interestingly I epoxied the magnets in, the epoxy expanded as it cured, had to grind the magnets down to sit flush.
Leaves a near mirror like finish on carbide, photo doesn't show it on the old insert I tired.

Free advice is worth exactly what you payed for it.
