When using the Underscribe Router both pieces of laminate are glued in place with one over-lapping the
other. The Underscribe guides off the bottom piece and cuts the over-lapping piece for a perfect fit.
When using the Seaming Router both pieces of laminate cannot be glued in place, one piece may be
glued and the other clamped, or both pieces are clamped in place with one piece over-lapping the other.
The Seaming Router cuts both pieces of laminate at the same time, leaving an 1/8” gap between the
pieces after cutting so one piece must be re-positioned.
One sheet is placed down and fastened firmly. Then align the other sheet, lapping from 1/8" to 7/8".
One sheet may be glued down, but the top sheet must move 1/8".
Clamps can be used, but rubber coated vise grips are much faster.
On joints over 25" place clamps on all four corners.
Edge of bottom sheet must be reasonably straight.
