Bicycle front fork tube cutting tutorial (2)

6. But if it is installed on a DIY car by yourself, and there is no original fork for comparison, please install the fork on the frame without cutting the pipe. Install the bottom stopper, headset, washer and stem (compact as much as possible to avoid frame or gaps in the headset), and re-measure the required front fork steerer length by adjusting the angle of use that suits you.

7. For playability and adjustable range, many riders can install one (or several) fork washers above the stem as a reference for cutting length. It should be noted that we need to mark the position of the top front fork washer of the interception tube, which is about two-thirds of the top front fork washer.

8. Then we can draw a mark on the steerer tube to facilitate accurate positioning when using the tube cutter

9. The front fork steerer tubes on the market are made of steel, aluminum alloy and carbon fiber. This professional front fork tube cutter is only suitable for intercepting steel and aluminum steerer tubes, while the carbon fiber steering tube fork Riders must use a dedicated carbon fiber hacksaw for cutting.

10. The first is the positioning of the tube cutter, because a mark has been drawn on the steerer tube before, so you are not confused when positioning, just use the blade of the tube cutter to align the mark and gently clamp it.

11. When cutting with the pipe cutter at the beginning, the pressure of the blade should not be too high. Use the blade pressure adjustment knob to gently press the steerer tube, and then start cutting in a circle.

12. Turn 5-6 times under the same pressure so that the blade can cut the steerer tube relatively easily, and then tighten the blade pressure and continue to rotate the tube cutter. After a few revolutions, continue to increase pressure on the blade until the steerer tube is cut. In the process, avoid applying excessive pressure to the blade and avoid damage to the blade and steerer tube. Everything must be done slowly. (Slow work leads to fine work)

13. Smooth interception, the cutting surface after normal interception is relatively neat and flat, but there are still some metal burrs that need to be polished
