    Internal spline reverse engineering

    Thanks for your answer. This is a low volume operation. As mentioned before, my production costs are not the bottleneck. A gear company will measure the internal and external spline of the hub and supply me a dxf with the spline. So basically the only thing I need to know is the material and...

    Internal spline reverse engineering

    Thanks for your reaction. The costs for machining is not a real problem. I can use an EDM wire cutter and a conventional lathe. I was planning to do this in the following order: -Create a DXF -Pre-machine the new hub on lathe -Determine original hardness. Match material hardness. Perhaps the...

    Internal spline reverse engineering

    Haha, o.k. They charge €350,- to create a DXF for me, don't know if this is a reasonable price. Perhaps you can answer my other questions concerning the fabrication/ hardening of the splines. Am I correct that I have to measure the hardness of the stub axle and match this hardness with my...
