Mine arrived today - no damage - phew! Started assembling it, OK until adding the plate extension. Wouldn't slide on. So took faceplate off saw and tried again. One one side there is a little, less than an inch, piece of track held by 2 screws. This was fouling the runner. Took it off and now extension slides on correctly. Very awkward refitting the table. I'm leaving it now till the morning. I'll try again then with a less frustrated head.
