Doweler Alignment Gauges
MasterGage tools help verify the setup references behind dependable dowel-hole placement. Check machine or jig position fence reference depth setting and workpiece registration before drilling a production run.
Machine Set Up
Doweling accuracy relies on consistent workpiece registration fence position hole depth and machine or jig alignment. Use MasterGage tools to establish and verify the relevant references before drilling parts. Make a sample joint first then adjust according to the tool manufacturer’s instructions.
