    Too good to be true?

    No, those seem to be popular. It's not the quality of a Walter or other high end, though I'm sure as good as any old clapped-out Ellis.

        There is a high probability that one will be entirely satisfactory.

            I have a Vertex version and it's fine, works well without any problems, not as good quality as a western world product but very good for the price.

                You have to be careful.
                The add states you can divide to any number. This is false, as there are a lot of prime numbers that can't be reached with the plates supplied.
                If you don't try it, you will never know if you can do it !!

                  One can always carefully make other plates.

                    True but John [ Blogwich ] was just pointing out the flaw in the advertising.

                      I know, I was making an attempt at humor.

                        It is not funny, you CAN make plates with any number of holes using the head itself. I have posted on this process several times and a search of the archives will reveal that explanation. These shop made plates will essentially be as accurate as the head you make them with.

                          There are several alternatives to dividing numbers by the "supplied plates":

                          - make a plate to suit ( good digital calculator will output the result in Degrees: Minutes: Seconds - so use the hand-wheel vernier.

                          - forget the plate/s and use a calculators as previously;

                          - use/borrow/buy a DivisionMaster and forget the plates and calculator all together.

                          DivisionMaster works in Decimal degrees and so you can use the values "as is" from your calculator without having to convert to DMS as you would have to if you were using a rotary table (which is calibrated/indexed in D:M:S).

                          John Stevenson is the "Wizz", "Go to guy", Guru and "Subject Matter Expert" on installing and using the "DivisionMaster (all, so far as I am concerned and in my case is very true) and its quite often using John's posts and methods that got me - in large part - to be as happy as I am with my DivisionMaster.

                          Thanks John.
