Angle Cutting

There are concrete columns which run vertically through the floor slabs, these columns protrude out from the building at an angle of 35.5°. The thickness of the columns equates to 5mm on my model which means I can accommodate their thickness by using 5mm thick acrylic sheet. To cut the angle accurately I used an inclinometer rather than using the angle guide built into the circular saw which I found to be slightly out.

To create the columns I used the thickness of material closest to the thickness which the actual column scales down to.


Again I used the inclinometer to make sure the circular saw blade was set to the correct angle before I started cutting.



The image below shows the circular saw guide when the inclinometer is set at 36°. Unfortunately it's almost half a degree out, out as can be seen, over the size of the column on the model this would be far too much to accommodate.




If the 8mm material was laid flat on the bed, the blade of the circular saw doesn't tilt over enough to create the correct angle. The best way around this was to cut a strip of material to the correct width, turn it on its end and then using double sided tape stick it to a piece of MDF which can then be run along the fence.
