Ever sinceI saw a hand crafted wood-framed glasses, I always wanted to own one myself. Instead, I decided to use this opportunity to make an enlarged, giant version of the wood framed glasses and use it as a shelf-object.
Above is the projected rendering of the finished shelf, however this prototype test only has lateral (?) bracing. I will be adding more braces on sides as well so the shelf can be rotated for horizontal use.
Using the Shotbot in 4-002, I started cutting the protype shapes on 30×40 MDF panel. There are three pieces, two end glasses frame with pockets to bracket the connecting braces, and one middle piece with cutouts to support the braces. However while I was putting together the three frames together, the center piece broke off, and it was also difficult to assemble. Also the middle frame seemed redundant. I decided to take out the middle frame.
Even with the pockets, because the pockets were along the curved edges of the frame, the connection detail didn’t turn out clean. For the final product, I will place the 1/4″ deep pockets along the center line of the face frame. Below is a view of the finished prototype (only showing uni-directional braces, this will be revised to include braces along the entire frame – multi direction).

Final production: A-Nader Shelf
Using Techno CNC at N-51, with 3/16″ bit and 4×8 plywood sheet
Close up detail of the joint (brace fits into 1/4″ deep pocket. ** Problem! I drew in the 1/4″ fillet in the cut file, however I over calculated the tolerance, and the pockets became too large. The picture below shows two different types of pockets (I forgot to delete the larger one), but even the small pocket turned out to be a bit large for the braces. I had to recut the bracing pieces. One problem with the Techno CNC was that when creating pockets, it did not cut to the true size; resulted smaller. So I had to create a profile first and then another pocket.
