Re: Mounting Cockpit Seats on a Floating Floor
Reply #5 –
Not sure I would bother to dowel the holes. Just use a sheet of aluminum larger than all of them underneath/top of wheel well and drill through it in the new bolt pattern for the new chairs. Seal with polysulfide around perimeter of the sheet.
To properly install a floating floor, find a thickness of plywood very slightly thicker than the flooring. Cut it 1" smaller in width and length than the seat pedestal. Install the seat on it. There is now a 1/2" opening under the seat mounting plywood all around. Install the floating floor with a 1/4" gap to the plywood. Visually you will not be able to tell, but the flooring will be able to move.
Same applies to any furniture sitting on the floor. You can make it appear that it is directly on the floor, but raises 1/16" or so above it (just enough to give the floating floor room to expand/contract) with the flooring going just under the furniture so it appears that the furniture is on the new floor.
Been there, done that!
