OBV Swivel Seat Mod (Very Popular Lately)
I took a similar approach to the others with a few changes.
Parts:
(2) 9" X 13" X 1/4" Aluminum Plates
(1) Swivel
(4) 1/4" - 20 X 3/4" Bolts
(16) 1/4" Washers
(Eight) 1/4" Locknuts
(Eight) 5/16" - 18 X 1" Bolts
(2) 5/16" - 18 X 2 1/2" Bolts
(4) Factory Flange Nuts (Originally held seat to rails)
(12) 5/16" Washers
(4) 5/16" Nuts
(2) 3/8" Nuts
(2) 3/4" X 1 5/8 Aluminum Spacers
My factry seat did not have holes in the center to attach the swivel to, so I mounted one of the plates to the bottom of the seat using 5/16" -18 X 1" bolts, washers, and factory flange nuts.

I then drilled thru the plate into the seat. The seat was hollow in that area, so I drilled the top out to 3/4" so that a socket would fit in to hold the nut.

I set the other plate on top of the rails and shimmed up to make the plate even with the floor. The angle worked out to be 6 degrees.

I set my adjustable square to 6 degrees and mounted it to my surface grinder.

Yes, the seat is more upright. I made the swivel flat with the floor, and that was the result. If I didn't, it would lean way forward when facing backward. I plan to try it out this weekend. If I don't like it, I am going to raise the front of the seat above the swivel. That way the swivel will stay flat and the seat will be tilted back like the stock position no matter which way it is facing.
