Vibration or is it resonant frequency. I have used heavy 2x4's to remove that. Use long timbers like more than 2-3 feet long.

A while back a BP owner who probably was on his fourth one said that they are not very stable and vibrate with moderate to large depth of cut.
Then I asked him why he keeps coming back for more.

There is such a thing as TOO stable

Drill 1/8th in holes on a #2 Horizontal.. Or a #4 vertical...

Where did that feel go?????

Horizontal loves big cuts, big work..

BP never designed to be a chippie monster.

Was designed to do things, not easily done on Stable machines...

Well, as I wrote in post #12, the problem has gone away.....
All is good now.
No idea why, but I'm really please with new drive set-up.
