Use to measure your yardage for weaving, spinning or knitting.
For warping with a sectional beam, place the counter on the tension box to measure the yardage of your warp; one revolution equals 1/10 yard (up to 999.9 yards).
Also useful when filling bobbins for warping (Winding the bobbins that go on to the bobbin rack using the tension box and counter to keep track of the yardage on the bobbin helps reduce warp waste.)
Support and pulley are made of maple.
