We moved up to a fillet on the new trusses for our Camera Slider and Skater Dollies. Until now, we were using a chamfering tool to mill a 15 to 25 mill chamfer on the outer edges but we decided to explore fillets which, needless to say, makes setting up and machining a little more complicated since both edges of the fillet need to line up perfectly with both flat surfaces in each side of the part. It took us some trial and error but we finally made it work. What a difference! It’s very subtle and might not be visible to the naked eyes unless you really look closely but to the touch and handling, it is quite striking! With contoured, round edges, it does not feel like corners against your hand. It is particularly noticeable with a heavier camera and head mounted on either our camera slider or Skater dolly and you lift the setup to change location.
Additionally long term, there is less wear and tear on the edges of parts with fillets since there are no sharp edges, unlike chamfers. There is also less anodizing wear and tear since the anodized surface wears faster and angled corners.
From engineering publication: a chamfer is a sloped or angled corner or edge, and a fillet is a rounded corner or edge. These edges can be located on either the interior or the exterior of a part.
Here are our new Level 5 trusses for our Camera Skater Dolly with fillets.
