Not sure how additional illustrations would help unless you mean to include specific example numbers. All content in the video created by UHP - not borrowed from a book.

If you have a question or if something is unclear, let me know how I can help.

The steps on how u started that

Since your request wasn't more specific and constructing the lines and arc are easy enough, I'll assume you are wondering how the 57.3 radius was determined. A circle has a circumference = 2*PI*Radius and 1/4 of a circle equals 90 degree so > 90 degrees = (2*PI*Radius)/4 and solving for the Radius we get R=(90*4)/(2*PI) which equals 57.3 inches. Does That clear things up for you?

To be correct, I wanted the arc to be 1" for each degree such that 90 degrees would equal 90 inches along the circumference.

The calculation shown (where the run and set are equal ) only applies to a 45 degree offset -for other offset angles, the run and set are not equal. You can calculate travel factors or use a table of tangents for other offset angles.

The same procedure can be used. The travel in each case (with all SET values being equal) will be the same. We are still using a 45° fitting to start the offset. The difference will be the pipe cut length between the fittings which is dependent on the takeout of both fittings. TL = CL + (F1TO + F2TO) WHERE: TL = TRAVEL LENGTH CL = CUT LENGTH F1TO = FITTING 1 TAKEOUT (45 elbow) F2TO = FITTING 2 TAKEOUT (90 elbow or TEE)

There are many ways to layout a rolling offset, but the video was made to show a method using only 3 simple tools - a square, a pencil, and a tape measure. If you know a different or better method to accomplish the task USING THE SAME SIMPLE TOOLS, show your method. I am always open to learning something new.

Yes - instead of 1 inch = 1 degree at a 57.3 inch radius, you can use a radius of 28.65 inches and have 1/2 inch = 1 degree or a radius of 14.325 inches for 1/4 inch = 1 degree. A folding ruler works very well for this.; Simply drill a small hole at the 1 inch mark which, another at (14.325 + 1inch), another at (28.65 + 1 inch) and the last at (57.3 + 1 inch) this gives you three options - just be sure you use the correct measurements along the arch when converting to degrees. You could use a permanent marker to write the inch/degree value on the folding ruler near the hole...... Hold a nail in the hole placed at 1 inch ( the center of the circle) and a pencil in one of the other holes to draw the arc. Then measure along the arc as shown in the video - the folding rule will bend along the 57.3 inch radius but not the smaller radius values.

Glad you liked it!

Please provide a reason to consider your request.

I would be interested in seeing a video of your method for determining the travel length of a rolling offset given only a vertical and a horizontal distance between two pipes. Please remember that only simple tools are to be used - a square, a pencil, and a tape measure - NO calculators or cellphone apps.

@@uhpprocesspipinginc5973 I don’t need to make a video. I was joking because most employers won’t let you take time to go through long processes. I’ve been bending pipe for about 25 years, and I went through pipe bending classes. I’ve taught apprentice and even journeyman to bend conduit on all types of benders. I was trying to find a simple video to show to a guy that doesn’t know how to bend rolling offsets, but his English is limited so this wouldn’t help him. Unfortunately I can’t go show him because I’m in quarantine right now. Don’t get so mad this ain’t no competition.

@@victhelion72 The response was not made in anger. The purpose of the video was to show a quick field method where a user only needs simple tools and doesn’t need to remember the Pythagorean Theorem. There are much better videos which show conduit bending procedures once the travel dimension has been determined. Google “Polly Friendshuh” - she has a series of conduit bending videos which might be of interest to you.

It is the same for both imperial or metric systems since the relationship between sides of the triangle are presented as a ratio (unitless)
