Thanks for the explanation. I wasn't saying that the side of the lathe bed should be square. I knew it would not be. My concern is to make sure that the bracket mount and the pickup are parallel to each other which is why I was checking the angles. In a worst case scenario, if your lathe had greatly sloping sides to the bed, the bracket that connects to the carriage would have to compensate for the angle. On my mill I had a situation where I had to make a small block with an angled face to allow the scale pickup to be square to the body of the scale.
