    Thanks, but the writing in the pictures is missing some serious punctuation in step 2, the picture is tiny and all the text in the table is thus not readable. I think the info might be of useful value if it just was presented differently.

      The drawing seems to refer to five steps but only steps 2 and 3 are shown.

        Very nice to share the knowledge,
        but exercising an accomplished command of the English
        language helps to get your point across.

          Having written a detailed description of compound indexing and a program to do the calculations all I can say is,

          I hope you don't do presentations for the company for whom you work.

            Here all the step print in the book
            This is closer tolerance that a CNC indexer / dividing head
            The chart has ever division from 51 to 250

            Compound Indexing using the Smith Indexer

            Step 1 Find the divisions need on the chart in this case 77 Divisions
            Step 2 Install the dividing plate in this case it is B (2)
            Step 3 Set the Sector Arm at 9 holes
            Step 4 Find the second hole circle need.
            Step 5 Make mark on the Smith Indexer for the second hole circle for indexing in this case it is 3 holes to move forward in this case 3 holes.
            { note some division will need to go backward in this chart displayed in (-##)}
            { Note all indexing need the Sector Arm Spring/retaining clip this holes the sector arm for sliding. Replace if you missing this part a compression spring is not as good }
            .

                      From the finest schools in the USA my high school was in top 50 in the USA
                      Writing does not pay the bills what I found some the top writer in the word will never be English professes.
                      Some else can find tune there work.

                      Bottom line how to want to write a book on machine work, a English professes or journeyman machinist

                          There is lot thing out there name Smith you are first to note I use my last name. I had name it some so why not.

                            OK guys, give the man a break. I, personally think that a good command of the English or any other language is a necessity if you are going to express your ideas accurately. When you write about a subject and the grammar and spelling are not correct, then the meaning can be lost. So you fail to communicate and many will not even read to the end. BUT, he has made an effort to simplify a subject that can be confusing to many, even some of those of us that do have better writing skills.

                            His project could be better written. A good explanation of how compound indexing works would be nice. Some additional information about the fine points involved when moving using two hole circles to avoid backlash would be nice for beginners. And the illustrations lack the detail needed to be useful.

                            I haven't examined his procedure in detail, but it probably has merit.

                            Perhaps one of you with better writing skills could volunteer to help him with his project.

                              What is compound indexing?.

                              The three normal modes are "direct","Indirect" and "differential"

                              The picture seems to be showing an original Brown and Sharpe design indexer (as knocked off by Vertex etc) , using bog standard "indirect" indexing ... As shown and explained ad infinitum on web pages and indexer manuals eg..Elliott B&S etc.
