I really didn't need the drop leaf table in my saloon. We prefer to eat in the cockpit, we can eat hold our plates if it's raining out and taking the table out really opened up the interior. Plus w/ numerous sails that I'm still sorting out...
Anyway taking out the table left four bolts sticking out of the sole. Even w/ the acorn nuts on they still posed a threat to bare toes and to klutzes that aren't observant of things.
I decided to put blocks of wood over the bolts to protect them and our feet.
Some years ago I scored some huge cutoffs of hardwood at the landfill in a dumpster! Mahogany and oak, 18x20x2"
I cut blocks of mahogany to match the footprint of the table, drilled holes for the bolts and then used a forstner bit to drill a hole for the washers and to recess the acorn nuts.
As an added feature I decided to cut a slot in the bottom between the holes to take a strap so I can tie stuff down in between the blocks; sail bags, plastic bins, etc. Just need to get a soft rug to lay on the sole so it doesn't scratch.
Of course you have to stain and varnish appropriately!
Total cost. $0. I had the wood, stain and varnish on hand.
