I am in the process of assembling the table. I am on the step where it says to "Square the Leg to the Upper End Support". Which I just can't seem to do. So I started looking and measuring and I noticed that the distance between the bolt holes where the supports attach to the table legs are different in the upper support vs. the lower support. I also downloaded the table plans and the plans confirm this (if I am reading them correctly). According to my measurements and those taken from the table plans for the PRTAlpha 96. It shows a distance of 58.5 inches from the middle of the end bolt holes in the upper support, and a distance of 59 inches from the middle of the end bolt holes in the lower support. So here is my question, with these two different distances, how can you square the table leg to the upper support when the lower support will be pushing out 0.25 inches on each side? This also will affect the rails too, and not make them perfectly vertical, right?
So I have come to two conclusions:
1. I have done something wrong in the assembly process, and there is a way to indeed get the table legs square to the supports.
2. This is meant to be, and the table legs (along with table sides, rails, etc) will pivot, or be on a slight angle to the inside since the lower support is pushing them out by 0.25 on each side.
Also, looking at the plans for the 120 and 144 inch tables, if I did my math correct, it looks like the distance is indeed equal on the upper and lower supports for these two tables. Which makes things really confusing and I start questioning my two conclusions above?
