Blade mounted in the Tri Scribe marking gauge shown here fixed to a standard
tri square. The Tri Blade cutting gauge provides high tolerance precision
woodwork marking and is ideal for hyper-fine marking, especially cross
The blade is very sharp and fine and is removable to allow replacement
sections to be added. The Tri Blade's sharpness and flat lying stability
mean there is a high degree of precision. Very light cuts or heavier cuts
(as shown here) are possible depending on the desired result.
The Tri Blade addresses certain associated factors of woodworking scribing
and marking out:
- Tear out - thicker or blunt blades can cause the wood to be torn
rather than cut - Tri Blades use very sharp high tolerance removable
blades and presents the blade's cutting tip to the wood at optimum
- Wobble - traditional cutting gauges lack stability - Tri Blade cutting
gauge is mounted on either a tri square or combination square which
provides a greater stock fence contact area and length to depth ratio.
The judder and bobble that can occur as the cutting blade traverses
rough grain is greatly reduced by having a flat lying unit with a
low centre of gravity.
- Precision - a finer blade means greater precision, and a removable
blade means it can be replaced with a fresh section when required.
Greater stability means consistent results, and consistency means
- Range - standard cutting gauges have an 8" beam. That means when
the blade position is taken into account you only have an effective
depth range of 6". By mounting the Tri Scribe unit on a tri square
or combination square the Tri Blade cutting gauge range is only limited
by the length of their blade - That means your 12" tri square becomes
a very effective and accurate deep range cutting gauge.
