Centre Finder

Beta This jig is in beta: the files are generated and checked, but the design may still change. Check the drawing against your instrument before you cut.

Centre finder

The body, both roller modules and the centre insert you choose, as printable files. Pick the span, the two rollers and the marker, and the bundle carries exactly those parts.

Widest workpiece The widest piece this tool must centre. The span is derived from it, and a narrower board is reached by laying the tool diagonally. 10.0 mm to 300.0 mm.

Typical widths

Thinnest workpiece The thinnest piece this tool must centre. Anything reaching below the beam further than the board is thick would leave the tool standing on it. 3.0 mm to 120.0 mm.

Pencil diameter The pencil this tool holds, measured across the flats if it is hexagonal. It passes right through the beam. 4.00 mm to 9.00 mm.
