since i was working with super glue it was hard to get any shots of putting the neoprene in place. the block helps out a lot for attaching any kind of scales with glue or epoxy that are pinless. i was gave the piece of plastic for spacer material and and found out it was resistant to any kind of glue so i never had to worry about the glued on handles sticking to it.
the tape makes it easy to get the sides even. i look down from the side and watch where the wheel is in relation to the tape so i can keep the line even.
since i clean up with the scotchbrite wheel i can be close to the tape line and not worry about the sides being uneven length. i sand the corners down on a roll sander before going to the scotchbrite wheels. they smooth the rubber nicely which makes it hard to tell any tiny difference
