In that movie in the previous post, I forgot to mention that the steps are angled downward, to match the actuality. Most of the time steps are either level or from 1/8" to 3/8" over the length of the tread, angled downward. It is good to draw the steps to see exactly what it will look like before you cut up, bend up a lot of pipe, weld, file, sand, and coat the rails. About six times actually seeing the job before it was built, it has saved us from making mistakes.

The drawing program General Cadd supports environments, that you can set once and save. That particular environment stores a 4.25 inch, inside diameter radius, that matches the pipe bender die, I am going to use for that pipe. When I draw pipes for other people and their pipe benders, or for different diameter pipe or tubing. I save the environment for the future, so I do not have to reset the automatic fillet radius, you may have seen in action while I was using the multi-draw function. That draws the pipe. The measuring macro, or tool, uses the center line, to create the marks on a straight unbent pipe, so the bends I draw must be the exact radius I plan to bend. We then use a number just a little smaller then pi to create an exact measurement. Apparently the pipe stretches a little more then it crushes, and it seems to be accurate on a wide variety of common pipe bending equipment.

These are the rails after they are welded, and sanded. They will go to powder coat next. They came out very nice and very accurately, thanks to the drawing program and drawing tools. A fun spare time project.

I diamond cored those rails into the ground two weeks ago. They fit perfectly and gave that nautical look. The fellow who asked me to make them, is a ship captain. He was very pleased with the results.
