I am trying to make a trangular tube on the table saw. I tried to cut a 30 degree angle so that when I joined the two sides I would have a 60 degree angle which is 1/3 of the 180 degrees for a triangle. This strategy created 1/2 of a hexagon. If I am thinking about this correctly I would need to cut a 60 degree angle on each side. I cannot figure out how to do this on the tablesaw. Does anyone have ideas on how to make these triangular tubes on the tablesaw?
thanks

If you can safely support the stock vertically along the fence, you would rip a 60 degree along the lower edge. This is usually not a safe process, unless the pieces are wide and long and you can use finger boards. In my shop, I usually perform this on a jointer, to which I have added a 45 degree, pie shaped filler to the fence and lay the fence over 15 degrees (left tilt, capturing the piece between it and the table), letting the depth down to make the cut in one pass. I usually strive to leave a narrow, say 1/16" flat on the corner, as otherwise it's prone to splinter or cut you.
Be especially careful.

I assume you are saying you want to rip the pieces w/ a 60 degree bevel along the length?
Off the top of my head, what about making a sled that carries the piece at the angle? Use toggle clamps or double-sided tape to hold the piece while ripping.
To make the sled you could cut a couple wedges at 15 degrees that would incline the face of the sled and angle the blade at 45 degrees. Combined you get a total 60 degree bevel.
Let me know if you can't envision what I am saying and I'll make a basic drawing.

If you need to miter the corners, you need half the angle, but if you offset them, the angle you cut will work.
