I have a niece that for her 2nd Birthday her mother wanted me to design and build her and Eiffel tower with shelves so we put our heads together and she wanted it to be 6-1/2' tall and 30" wide and the depth of 26" so I drew up the plans and the materials are of a 4x8x3/4" sheet of melamine (MDF) and the cutouts were from 1/2 popular, carpenters glue, super glue extra strength to glue the cut out on 1-1/4" and 4 inch screws. All total they are 264 pieces in this project. Tools used 18v Ryobi Drill, 18v Jig Saw, Ryobi Bench top belt dis sander and Ryobi Scroll saw. This project from drawing design to completion took a total of 125 hours, lots of time and patience. I have built two and no more they are way too time consuming but both ladies where very pleased for their children to have these and hopefully will pass them on to ther children someday.
