The final step in securing the concrete tabletop to the contract base is to glue the shock mounts in place.
Here I’m using smooth-on metalset A4 epoxy, and tinting it black with dry pigment.
First the base is centered on the tabletop by measuring from each leg to the outside edge. The base isn’t perfect, and there was some variation in the length of the four ‘arms’. After getting it roughly in place, make some marks with a pencil and attach the shock mounts, then draw circles around them and make crosshairs so you’re still able to see where they should be when the glue squeezes out. I also labeled position 1 with leg 1 on the base so it didn’t get mixed up.
Squeeze out the epoxy, add in a little bit of black pigment, and mix until it’s a uniform color. Then glob some on where the mounts should be on the concrete, and put some on the bottom of each shock mount. Place the base back in place and wait a few minutes, then unscrew the bace and let the epoxy cure for a day.
This was only my second time gluing mounts in place, so they aren’t pretty, but they lined up to the base just fine.
Place the tabletop on the base and screw the mounts in place. Erase the pencil marks and that’s it.
The tabletop is secured to the base. The only thing missing are the table-base levelers, which I’ll make next. The blue chairs look pretty nice with the orange top. I’m happy with the color and it should hold up just fine outdoors.
