It is done by using a dressing wheel to create a radius to the face of a grinding wheel. This is a common method of creating a “Fish-mouth” in the ends of tubing used in aircraft construction.
An effective method of preparing these tube ends for the joint is by forming them on a bench grinder. This is due to the limited travel distance of the hole saw. Step 6: Most hole saw tools will not make long, shallow cuts like the ones at the ends of part number WP-908-3. Step 5: Similar to the above steps, make the necessary bends to create part number WP-098-3. Step 4: Cut the length of tubing for part number WP-908-3. Make sure the “frame bottom” lays flat on the work surface before and after it is welded. This should be a flat weld bead all the way around the tube. Step 3: Weld the ends of the tube rectangle together. Make sure the tube ends are within a 1/16” from each other and facing each other in the middle of one of the shorter legs of the rectangle, as noted on the drawing. This will be the bottom of the go kart frame.Īfter all bends are made, this part will be a rectangle. Step 2: Using a tube bender with a ¾” X 4” bending die, make the bends in the tube to create part number WP-908-2 as shown on the drawing. Step 1: Referring to the cut list on page one of the drawing, cut a length of ¾” X.

This can be accomplished by adjusting the height of a take-up table or surface to correspond to the bottom of the tube. Otherwise, the tube form may become unusable. Whenever you make more than one bend in a tube form that must remain flat, pay particular attention to the plane of the tube prior to each bend.However, if either TIG or the Oxy processes are used, the weld joints need to be particularly tight. This project is intended to be completed using either MIG, TIG, or Oxy-Acetylene weld processes.
