| Line up the two holes in the loose half of the metal assembly with the two longer flat-head screws at one end of the bed, and pass the screws through the holes. Then shift the other part of the metal assembly until the third flat-head screw lines up with its hole. Check that all three screws are vertical and not tilted. (The shorter screw may not be long enough to reach the hole in the T-Plate, so just peer down the hole and look for the screw.) | Line up the two holes in the loose half of the metal assembly with the two longer flat-head screws at one end of the bed, and pass the screws through the holes.

| - | When everything lines up, apply just enough pressure to the flat metal piece to prevent it sliding over the straight pieces, and gently tighten the four loose screws, just until you feel some drag on the screws - you don't want to damage the bed when tightening the screws). Then carefully lift the metal assembly off the screws and move it to another flat surface, and tighten the screws the rest of the way. | + | When everything lines up, apply just enough pressure to the flat metal piece to prevent it sliding over the straight pieces, and gently tighten the four loose screws, just until you feel some drag on the screws - you don't want to press down on the bed so much that you damage it.

| - | Attach the bearing assemblies (insert a rod - carefully - before tightening the screws to ensure proper orientation of each pair of bearings) and the tensioner parts to the metal assembly as shown. The exact positioning of these tensioner parts will be determined later when assembling the [[jitsbuild-y-axis|Y axis]]. | + | Attach the bearing assemblies and the tensioner parts to the metal assembly as shown.

| + | Get out one of the precision steel rods and use it to make sure the linear bearings are straight before you tighten the screws on the bearing holders. Make sure you insert the nice end of the rod, and don't bang the end of the rod against the bearing balls inside. | ||
