Thanks for the picture. I suppose I'll have to GOOGLE tipping wheel as I'm not familiar with that terminology. In the picture of the tipping wheel you shared the key it appears would be the rigidity (or lack of flex) both where that arm is bolted to the vertical RAS piece and the connection between the horizontal head piece and the vertical stand of the RAS. Jeezzzz...I hope I'm making myself clear here. I haven't studied the RAS enough to know...is the connection between the horizontal head piece and the vertical stand really flex free?
