Common sense and experience has to come into play when you are building any type of fork system. Then there is the matter of fork offset.

Single-current-sensor-based active front-end-converter-fed four quadrants induction motor drive. It's looks complicated, and to a point it is as there are certain engineering and fabrications constraints that apply to any single arrangement.

Unfortunately Springers compared to other types of forks are somewhat material intensive so it is pretty hard to save a bunch of money on the raw materials.
Many pieces won't actually reach their final stage of shaping until after everything is assembled. For now this is just meant to illustrate the general methods that can be used.

- What we're using is the simplest method since this is supposed to be a low-buck straightforward project.
- Buying or building a Springer is just the first step in a long process of getting it fine-tuned to your particular bike if you want to optimize it's performance.
- One of the weak points in girder forks is the inability to adequately resist torsion forces that are applied in a line perpendicular to the steering stem axis.
Make sure that the borehole for the stem in relation to the centerline of the rear leg is accurate with respect to the offset for your finished trees. After welding and final grinding and sanding to get a perfectly smooth and seamless surface on the tree you can drill the boltholes in the plugs to the final dimensions for your cap screws.
