1975 Harley-Davidson FX - Weld-On Hard Tail - STC -Tech

Part of the alignment process is to check the side-to-side alignment of the rear section. To that end they have used a piece of square stock to create a centerline; the stock is resting on a length of tape stretched across the frame near the axle plates.

With the lower sections of the frame clamped together, the final alignment was triple-checked from every direction.

The lower section is tack-welded on either side of the frame. After checking all of the dimensions again, the frame is welded together, doing a small amount on one side then moving to the other side to prevent the frame from warping.

Here's the underside of the top frame tubes. All welds were full penetration for maximum strength, with frequent checking on dimensions.

The finished job-so far. The Shovelhead has a completely different stance. The bike is still a '75 Harley-Davidson motorcycle, but it has a more, dare we say, chopped look? Stay tuned for more modifications and the finished bike.
