Base for a grizzly 6" jointer
 

The base on my 6" grizzly jointer is too flimsy for my tastes. It
vibrates even though I've carefully adjusted the motor and cutterhead
pulleys to be on the same plane, and I've even gone as far as putting a
thin layer of hard rubber tape between joints the sheetmetal to reduce
vibration and noise, but it's just not enough. What I would like to do
is build a solid base out of 3/4" MDF. The heft and rigidity of the new
case would be an order of magnitude better than the flimsy sheet metal
case. Has anyone done this before? If so, how did you handle the motor
mount? I intend to mount the motor with the mounting plate facing down
instead of that bizarre angle Grizzly uses (because the motor is mounted
to the exterior of the dust chute). I'm planning to secure the motor by
bolting it to a solid 1 1/2" platform mounted perpendicular to the
interior walls of the MDF case (a side view of this would look like an
"H" with the motor sitting in on the crossmember between the verticals).
This would give me a nice clearance for a 4" elbow for chip collection.
If anyone had a drawing or photo of your version of this idea I'd be
grateful. If not, I suppose I'll post my final result if anyone wants to
see it.

Had the same up at school, though the base was the least of its problems.
Screw a fitted 2x2 in the four corners and it'll quiet a bunch. Won't flex
as much, either.

Other than that, mount the motor to a piece of 3/4 ply and hinge it for
adjustment. Long bolt will keep tension where you want it.

Have you thought of leaving the metal frame in place and wrapping it in MDF
or plywood? Just screw panels to the outside of the existing frame. It
will add mass and stability.
