Motorized = cutter mounted on the motor axle. Belt drives supposedly are better
since they isolate the cutter fro motor vibration somewhat, thus increasing
I myself am mulling over jointer tradeoffs. I'm not sure but I can say the
Precision is the bottom line in a jointer. It exists for this reason. Otherwise
you could plane, belt sand, saw, etc. (and some of these options do pretty
well). So if it's not precise, the jointer is mostly worthless (though it is
*fast*). Unfortunately, accuracy is difficult to assess through casual
inspection. Even more difficult to assess is how well the unit *holds* its
accuracy over a period of time. One reason to buy Delta is the confidence their
reputation instills regarding these issues.
More specifically, I suspect the $1000 delta you mention has parallelogram
table supports, whereas the Griz probably has dovetailed ways with gibs.
In the former, each table is supported on the base by two arms. All four joints
