The LM12 is designed for using 8mm metric bars, which is very convenient for people who cannot obtain the originals or when the 12mm bars are not found. To do this: Instructions you should reduce a little the LM12 so they can enter with ease, you can use fine sandpaper to smooth out a bit the surface and edges. You have to enlarge slightly the hole where the 8 mm rod passes through, you can use an 8mm drill or a 5/16-inch twist drill and it will be very well done. It is recommended to use a bench drill
