Recently bought a Garelick flush mount unit and thought I could use a different pedestal which I had original to the boat as well as the table top . I used 5" bolts with washers and a 3/4" back plate . I need to buy the correct Garelick pedestal to fit properly into the plate but my question is with the table top . I would like to make one out of cherry in an oval measuring 32" x 16" . Has anyone done this before, is what I have done up to this step correct ? Do all pedestal tables give a little ?
