I have done the MS1 extension out of plumbing pipe and GS1000 pads and I really like it. Now I am making limba wood cups, including an extension, with the side wall 1-2mm thicker than the original.
I plan to take the driver out of the original and then install it in the wooden cups (oiled and sanded to a tight fit) the same distance from the outside "grid" as the original. I will use GS1000 pads.
Does anyone know if this is likely to result in a perceived improvement?
