Coffee tables are fun projects to build. They aren’t very big, easy to manage alone, fairly cheap to build and a good platform for your imagination.
This time I have decided to go for that industrial look with big heavy hardwood railway sleepers and a custom made polished concrete top with a wrought iron edge.

After cutting them to length, I arranged the sleepers in a way that shows off the beautiful ageing and patina they have. The packers are there while I screw them from the back. The finished look will be one of them floating.
Next was the concrete top. Well after some trial and error i have decided against concrete all together and am now going to use structural non-shrink grout. It is a shitload harder and finer. There will be no sand in it so the finish will come out more like highly polished concrete or that of polished stone. The difference the way i will be pouring this slab is i am doing it upside down. As in once its dry, the bottom molded side will be the top. In this picture the mold i have made from 18mm MDF whiteboard. The stuff your kitchen cupboards are made of. Its only temporary as long as its smooth. Remember, the inside size of the mold will be the outside of the shape you want. The depth of the mold will be the finished height of the slab.
Here is the sheet of 18mm form ply I will be using as a sub-straight under the slab. this will stop any distortion causing the slab to crack. Notice I am using a product called Hexa Birch ply. Expensive shit but it has that hexagon pattern which will help bond the two surfaces.
Ok, the steel frame has since been powder coated clear (to stop it rusting and also so it feels smooth and you cant get dirty fingers by touching it.) As you can see, i had to route out the bottom of the form ply by 2mm so the top edge of the steel is flush with the top of cement top. A small miscalculation, easily fixed.
