How big of a sanding disc are you going to make?? Is this just for pens or othe things such as large bowls. ???

Do you have a faceplate. What I did was attach a piece of plexiglass to my faceplate with double sided carpet tape. I have since changed to a piece of sheet metal. I use it for sanding small items. It is a 6" faceplate.
I'm more worried about it coming off easily.

One approach might be to apply some type of surface treatment. If you try Corian, for example, and find it to be too "sticky", then a coat of wax may yield good results.

What did you attach the Corian to to attach to the headstock? Corian is pretty heavy material.
The lathe came with a super-cheap 3" faceplate so I used that. There's 4 #8x1" pan head screws attaching the faceplate to the corian. After turning it round, which was quite the adventure since I've been turning for all of a week now, it runs very, very smooth. The big shocker was how long it takes to come to a stop! There's a bit more rotational inertia now.

That's what I thought you did. Yeah, that extra weight will keep it spinning a little longer. I hope the Corian was at least sort of round before you started turning it. Turning off corners would not be fun.
Yeah, it wasn't out of round by more than 5mm anywhere after I finished with the bandsaw. I took it down to round with a spindle roughing gouge. I tried a spindle gouge too once it was pretty smooth but I couldn't make cut the corian, for some reason. The spindle roughing gouge initially made nice long ribbons that covered me head to toe more than 2" deep. I looked like one of those confections covered in shredded coconut! Before I got done, the gouge was dull enough it was making powder and I was about to go sharpen it but then I realized I only had a 10mm by 2mm spot that wasn't perfectly smooth so just stopped at that point.
