When I placed the steel ruler of the machinest square in the slot width wise. As if I was ripping the ruler on the TS but had it stood up on end. One end of the ruler fit in the slot perfectly and I could not twist the ruler at all, it was locked in, the only thing I could do was pull it up out of the slot. But when I put the other end of the ruler in the miter slot at the same spot the fit was loose. I could spin the ruler in the slot. I hope I explained this well if not I will try again.
Is this a reasonable amount of imperfection in a $60 machinest square? I am guessing it is only difference of less than 1/32 of an inch but I am not sure. Any advice would be much apprecaited.
