WellRC Racing WellCut lower cut line tool
The WellRC Racing WellCut on-road lower cut line tool makes quick work of marking accurate lower cut lines on the front and sides of on-road body shells. The 3-D-printed tool uses a standard, but not included Sharpie marker and positions in 6mm, 7mm, 8mm, and 9mm heights are clearly identified at the top of the gauge. To use the tool, insert the marker, select the desired height setting and run the marker along the lower cutting line of the mounted body. The cut line is now clearly marked and allows for the most accurate cutting.
