Get a Dremel tool. you will need it sooner or later. Get it sooner because it makes life easier. I am on my third in thirty years. I just wore them out.
Tubular Track cutting. I use a 1 inch diameter disk. Place the track with the cut slightly over the edge of the work bench. Clamp or weigh down the track so it doesn't move. Cut the track about 1/4 longer than needed with an angle cut. Then go back and cut the track again to the proper length with a vertical cut. When taking off only 1/4 inch, you can get the Dremel tool in the proper position for a vertical cut.
