Hi Paul,
One thing you will see is the main table is higher than the frame that the clamps fit to, either shim to low area up or extend the clamp arms or heaven forbid tilt the blade to compensate. dont rely on the angle scale if you want precise cuts, precise in engineering terms is less than a third of a degree for open limit work but this saw for the money will do that if you take the time to tweak it in. BTW did you get a new blade with the C grade saw, if you did all I got for the extra cost was a big cardboard box haha, mind youif the gin palace sinks I can always sleep in it
regards
John
