A bike frame requires brawny steel tubing.
Provided you comparable choppers, you may carry consideration approximately building your own. Welding a bike frame is not rocket science, on the other hand it does wish the appropriate tools. You committal a Gauze metal arc welder or a Gauze tungsten arc welder, which creates a high-reaching flush of heat and a exact tight bond, and the genuine type of steel. Most motorcycle frames are built with DOM (stressed over mandrel) steel tubing, which is fixed Sufficiently to control the substantial engine and hire the physical stress of way drive.
Instructions
1. Figure a frame jig to the amount of your frame. Then section your steel pipes to the Correct length for the backside rails, steering yoke and centre brace. Reduce the two rear axle frames to length. Concession an additional Four to Five inches on Everyone frame quantity in condition you conceive a blunder on the weld; you can intersect the weld off and alpha over, instead of rebuilding the plentiful frame. When you constitution the allot for the rear axle, assemble trustworthy you report for the additional length that the axle holders Testament add. These you Testament compass to shop for separately.
2. Intersect the lower rails to the length of your representation and place them away. Attach the metal engine plates to these rails with a energetic weld. Be persuaded you keep measured your engine field true and allowed space for the seating bolts and other attachments your engine Testament want.
3. Weld the yoke decrease to the lower rails. This yoke comes together at the steering tube with room for the tube to be inset between the two pipes. Weld the two yoke sections together with a brace plate, then fit the steering tube to the yoke and weld this to the frame. Remember, the steering tube walls are usually 1/4-inch thick and much wider than your frame pipes. Your steering rod goes through this piece.
4. Cut and fit the center bar to the steering yoke, then measure the distance to your rear bars, where the rear axle will be held. These bars can be in any shape you want, but usually fall from the center bar in a straight diagonal line. Weld a center support brace to secure these two pipes together. Always measure twice to be sure the wheel you want to use fits between these bars, then weld a support brace connecting both rear bars to the center bar. You should also dry-fit your wheel and be sure it fits perfectly.
Weld on any extra fittings for the engine block, the seat and any wire harness hooks or bolt seats for the additional parts that you want on the bike, like the blinkers, gas tank and rear shocks. Hopefully, you have these all measured out on your plans.9. Fit your axle carriers and gaskets for the steering and forks, just to be sure they fit, and slide your steering pipe into the tube, if you have it already. It should fit cleanly; don't use grease. After everything is done and tested for stress, you are ready to paint your frame with a high-temperature, rust-proof primer and apply the final coat.
6. Weld your main support behind the engine plates to the lower rails and center rail. Now your frame is mostly complete. There are still a few more steps to take, like welding on the parts to hold the wheels and testing the overall strength of the frame.
7. Fit and weld the rear axle assemblies to the bike frame; carefully remeasure and dry-fit the rear wheel again before you complete the weld.
8.5. Cut and set a brace on top of both rear side tubes behind the engine block and weld it secure. Weld your cross braces to the two side tubes below the center bar near the back of the engine.
