I have had great success with the foam blocks
and have always used them, but If you don't like the foam blocks you can
always make foam cones out of the sanding blocks.
I removed the sanding surface
and cut the pad in half
I glued the two halves together with 3M super 77
adhesive spray.
I cut the foam into two 1 1/2" x 1 1/2" blocks.
I used a flat washer with screw and nut, also used some double sided
foam tape to secure the foam block to the flat washer.
I used my drill press and 60 grit sandpaper to
slowly form the foam block into a cone shape. You may want to wear
breathing protection. The process does make some dust. It probably took
me about five minutes to do.
The double sided tape becomes less sticky, so use new tape for each cone
you do.
