On my LP12 I used the following approach to set-up a new set of springs. I placed the LP12 between two small coffee tables so I could go underneath like a mechanic under a car. I also used a 100 watt lamp to light up the bottom so I could see clearly. I next removed the old springs completely and this left the assembly sitting on the top plinth. Of course I also removed the inner platter and main platter.Next I used a pencil to marke some parallel lines on the bottom of the plinth. Using the rectangular bottom plate as the guide, I manually centered the whole assemly so that the screws were dead-center. I marked three lines using the edge of the metal plate as indicators for physical alignment of all screws dead center.
This way, when I put the new springs back on, I knew exactly where the bottom plate had to line-up so that each screw was physicaly centered without actualy having yo look inside the springs.
It took me about 45 minutes after this to re-tension and line-up the suspension and the release the tension on the rubber grommets after turning the screws to center the asembly. I repeated this until I got the suspension to be physically centered.
You need to look vertically up from the bottom along each of the bottom plate's edges to see when it each border lines-up with the straight pencil marks. The border of the bottom plate served as a straight-edge when pushing this up against the bottom of the plinth as I made the straight pencil lines to indicate dead-center physical alignment.
Also I made sure that the alignment of the arm-board was also correct before making the guide line marks.
I myself find it very difficult to see when the screws are centered, it's almost impossible to see-through the springs. This is why I opted to make some straight pencil marks to know where the bottom plate assembly would be physically lined-up to have all 3 screws dead center and the arm board properly aligned with the edges of the rectangular opening on the plinth.
You then need to make sure that you don't over tension the screws and springs while checking that the suspension has the correct play and can move about the vertical axis of each spring while centered.
You should not hear any noises or rubbing sounds. Also a good idea to connect the cable to the tonearm and also fasten this with the P-clip while making the final adjustments for proper freedom of movement.
Hope this helps.
