Jerry H.,

I saw your post and I noticed that nobody replied.

I think that silicon coated rubber is one of the better belt materials.

The Japanese made Van deGraaff sold by NADA Scientific uses it:

The USA Representative for NADA Sci is Nouri Dassi:

Perhaps he can supply you with the belt material.

For tips about splicing and joining the belt there is a TPT article about
that by a guy you know:
