The windscreen arms are not sand cast. The process is too slow and labor intensive. From a cost stand point if the part was produced by this method, they would easily run away from that type of prodution method. No doubt, like the high quality billet windscreen arm produced in Austrailia, the best arm can be machined from billet. Less labor, with a tradeoff of time on the machining center.
Recently, I noticed another brand of windscreen arms. For some reason this latest entry costs 30% more than the Australian version and omits the details of the hexagon shaped bore to match and properly support the arm onto the torsion shaft.
Ironically, I have read many times the cause for failure is the arm is not capable to have the windscreen positioned in the full up or full down position. Myself, this concept of failure does not seem viable, however, I would consider that front tire vibration is absorbed into the arm causing the failure.
.........If they aren't SAND CAST .... then I'm interested in how you think they are made ??? ...................Thanks ...... Mike :thumbup:
