I installed a pedestal table last year with 1Ē long screws into my 3/4Ē plywood subfloor. I didnít get good results with that method as the screws had limited bite before they began to strip out.
I had a decent amount of wobble and the table never really felt securely screwed down. As a result, we traveled with the table pushed down in its lowest position.
Iíve just installed new flooring and have reinstalled my pedestal in a different manner. Iíve used toggle bolts from Toggler https://toggler.com/products/snaptog...steel-channels
and 5/16Ē bolts 2Ē long. This has removed a great deal of the wobble since Iím able to really tightened down the base without worrying about stripping out screws.
However there is still some table movement due to the flex of the pedestal tube. Iím installing this weekend marine wall and table brackets to give the table something else to support it when it is extended.
I bought Sea-Dog brand brackets from URL]https://www.go2marine.com/sea-dog-table-brackets-wall-mount-stainless [/URL] but I canít recommend them. The finish on them is horrible. Iíve ended up buying much nicer Perko brand brackets off of eBay.
The table bracket mounts on the underside of the table top and then rests into the wall bracket when the table is at itsí almost highest position. If I want to lower the top into the bed position, Iíll just raise it enough to come out of the wall bracket before we push the pedestal down.
First road trip next week to see how the new install does.
