In this post, the panel above shows my cafe chair in its cafe environment. I have chosen the Brother Baba Budan which is a small cafe shop located in the CBD of Melbourne. The first thing that strikes you when you, walk into Brother Baba Budan, is the unusual decor. If you have not been there before, you cannot help but be struck by the image of tens of chairs suspended high from the ceiling. The environment of this cafe is one of a kind and it's design in a way has a similar feel to my cafe chair as well.
The above shows the finishing method which I used. The very first was sanding down the chair by using an electric sanding machine to clear off all the rough and sharp edges. The following is by spraying primer to the wood to avoid the wood from absorbing the paint spray. Finally once the primer is all dry, the final step is spraying the paint. This has to be down a few times to give the chair the proper finishing. In between the sprays, the chair is sanded to give the final outcome a smooth finishing.
This sketch was an early fast sketch/render to give me a feel of how the chair would look like before I proceeded to my next step. As shown, I have taken out the plywood seat and changed it into a more interesting design by usingthe 4 mm wire. By doing so, it makes the design of the chair more interesting.
In this post, I'll be showing the kinds of locking system that I thought of to lock the 6 sides of my chair together. I played around with the thickness of the plywood and 4mm wire mixing and matching to come up with a suitable locking system and came to a conclusion that the best way to go about my chair is to have 3 pieces of 5mm plywood stick together to give my chair the proper strength so that it would not break.
In this post, I would be showing a JPEG image of the AutoCAD file which I handed in for laser cutting. In the picture you would be able to see 4 different line colours (black, blue and red, purple). The black represents the outline of the chair parts which would be cut through and the red would have a 2mm recess. As for the other two colours, blue is for the 'through all' cuts within the wood and the purple would be a recess of 4mm.Each part of the design contains 6 similar shapes. Every 3 pieces would be sticked together accordingly to increase the thickness of the material and would have a mirror image of the other 3 pieces making the design symetrical when assembled together.
Following up in this post is concerning with the seat of the cafe chair which I am modeling up. The material and design of the seat would be changed to make the design different from the usual cafe chair. The seat would be made using 4mm thick steel wire in the shape of a spide web. The jointing of each part would be welded to each other. The outer most layer of the web would have double the thickness to enable it to be slotted in a 4mm groove/recess which would laser cut into the plywood.
This is the updated version of the previous chair which has its high backrest chopped off. This design is lighter than the previous design in terms of the amount of material used and is more suitable as a cafe chair. There are going to be some slight changes with the final design which includes some modification to be done with the locking system. With this design, the locking system could be seen from the outside but as for the new design, the locking system would be hidden in between the three layers of wood which I would be using. This gives the cafe chair a more simplified and cleaner look.
