1) Center a leg mount/floor flange over each leg mount center marked on the table bottom.
2) Each leg should line up with an angle bi-secting centerline with the leg pointing outward away from the center of the table. The figure at the left shows what it would look like with the legs installed - leave the legs off till the mounts are screwed in place.
3) Clamp the leg mounts in place.
4) Using the leg mounts as guides, drill small pilot holes in the table bottom for the screws.
