There are curved blades on the top two floors of the building which create the staggered effect with the glazing. I opted to make these initially on the CNC machine, however it was proving too busy at that point to get on the machine as it was being used. I decided to look at alternative methods of making the blades.
Initially I opted to use chemiwood which I would then chamfer on the circular saw and then cut into 12mm strips. However this was proving difficult to cut into the 2mm thickness that I needed the strips to be.
The next option I looked at was to use 2mm thick acrylic, this would remove the need for me to accurately cut the material to the correct thickness, all I had to do was to cut it to 12mm wide and then put the chamfer on the material to create the diamond shape. It was the chamfering of the material which proved to be difficult, I was intially chamfering strips of material 600mm long, due to the changes in material thickness over this length and having to stick it to a piece of MDF which I could then run along the fence of the circular saw, I was getting various results for the chamfer as well as chipping at the point as can be seen in the picture below-
I then decided to cut the strips down to 85mm long which was the length I required and then chamfer the material by angling the circular saw blade and using double sided tape sticking the strips to a piece of MDF, this was a time consuming process, however I was getting much more consistant results.
