I have the Emerson BS1400 and also had vibrtion that I though was excessive. I now have a machine that will pass the nickle test from startup through shutdown.
1. Throw away the junk blade. Usually bad welds
2. Link belt, Link belt, Link belt. Best $21 I ever spent.
3. Use a quick clamp reversed to push the motor away from the saw. Learned that little trick from UO_Woody and gives you the exact tension you want.
4. This is something I tried and like. Got a extra stall mat for the horse trailer. We use them at work in the gym under the free weights. I cut a piece the size of the motor base and put holes in the appropriate places. I hate those little rubber gromets they provide. It makes it easier to bolt the motor down easily and does not slip at all.
I came...<br /><br />I saw...<br /><br />I changed the plans.
