Purchased this for my son-in-law's birthday. I realise it's not an expensive unit but there were assembly issues. The removable belt table is held to the machine by 1/2 inch piece of round bar and locking grub screws - this bar has two flats to line up with the grub screws, the flats should be 180' opposite each other or the table isn't straight when tightened - we had to mill this bar to align the table. Also, be careful with the spring loaded knob which you would think adjusts the belt tension - this actually adjusts how true the belt runs on the machine and is quite sensitive - adjusted incorrectly and the belt runs off the side and will damage the steel guide.
Anyway, it's all working now just needed TLC.
