I was working on a very narrow radiused hollow form that had some cracks filled with epoxy and metal. I attempted to use some 1" HL sanding disks which separated immediately. My 2" diameter disks with soft backing are too wide to get this job done. So should I go to pressure-sensitive backing or try again with hook and loop? If so, what brand and type works well at this 1" size. I want to stick to 1/4" shaft and stay away from the Dremel like 1/8" size. Any positive feedback on the type and manufacturer that is durable at this small size would be helpful.

1" sanding disks: Hook and Loop? or PSA

Well, most common reasons for the discs failing/coming off is too fast rpms with the drill, and too much pressure which equals more heat and the loop part comes off. PSA discs would react the same way. If you have some 1 inch inside diameter pipe, sharpen to a 30 to 45 degree bevel, and small inside bevel, and punch out the centers of some old discs. I am too frugal to buy them...

Here is picture of what robo uses only 2".
Also here is picture of disk holders that I made. Cut with a 2 " hole saw with pressed in hex drive bits. If you don't have quick connector for hex bits, HF has QC bit extensions. The pad is cut from a kneeling pad purchased at HD. Use Velcro heavy duty at hd also. If you over heat as robo said the glue will loosen.
You could use this same method to make "neater looking " 1" holder.
