So I am trying to fabricate my own extension for a pole saw. I was planning to use a shaft and spline from an old straight shaft stihl, but the spline from the Stihl is square, and the spline I need requires a 9 tooth 26mm spline...Does anyone know if any particular brand of string trimmer uses a spline like this? Or possibly is there an adapter I can use on the square shaft spine I already have. Let me know!
