Thank you for viewing! This is a jig set for a single-axis rear backslide anchor skid roller. See the first image. The second image shows everything included. Compatible chassis are VZ, S2, FMA, AR, MS, and MA. If you cut the jig in the third image using the shorter side as a guide, it will fit the above chassis, but chassis with tapered bottoms like AR and MA need to be flattened. *Be sure to cut with the shorter side. The fourth and fifth images show the completed image. The sixth image shows the amount of backslide. The seventh image shows the return. The eighth image shows the parts used for the shaft. The mushroom is pierced, and a 3mm brass rod is inserted. The countersink of the anchor is cut, but a 45° chamfer cutter is recommended. The ninth image shows the parts used for the skid roller. The shaft is the short one included in the MS multi-brake set. Next is a bearing washer, 830 bearing, bearing washer, 1.5mm spacer, 12mm spacer, 6mm in the middle, and the same on the other side.
