The dry run gave me confidence in the lines between the main riser block and the wood accent strip. But, after gluing it up it appears, before sanding away the excess, that the gap enlarged a bit. Did I slather on too much glue and it is holding the pieces apart ever so much?
A 36 grit sleeve was used to spindle sand the riser cuts. Maybe the grooves were so deep they held too much glue that the clamps couldn't squeeze out.?.
