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 in the product. 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 made flat. *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 through, and a 3mm brass rod is inserted. The countersink of the anchor is cut, and 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, and 6mm in the middle, the same on the other side. Please check the images for details. We also sell various other jigs, so please take a look if you like. We offer a 100 yen discount for each additional item when combined. If you have any questions, please feel free to contact us.
