      I have a bought a partly built Quorn. I also bought the book to help me with the construction. The casting for the rotating base was missing so I decided to make it from mild steel. I am near to completing it and have just noticed at the beginning of the book there is a note to say that the design of the base had been changed because of the difficulty some people were finding in machining the casting. Were these changes detailed in ME? If so can anybody tell me which in issue it is featured or can anybody give me the details of the changes?

      Thanks, Norman

          If you built it from the book it presumably incorporates the changes…

            That's the point. They are not in the book.

            Why would I be asking if it was there?

              Might try 3813 as that says its about alternative machining methods

                Try 5 Sep 86 (3784) page 272 , and 20 Nov 87 (3813) page 610, for alternate ways of making the rotating base.

                  Thank you Jason and John P, that is exactly what I was looking for.

                    Some people have made the base in two halves, top and bottom, it makes machining the circular t-groove into something mere mortals can achieve.

                      This is how the rotaing base is fabricated for the Bonelle T & C grinder

                        Funnily enough I found that cutting the tee slot was relatively simple. I just followed the instructions and ensured that the tools were set up precisely. Making the cutters was complicated by the fact that I don't have a tool and cutter grinder! I just used my angle grinder very carefully.

                          When I made mine (From the Book) I did it in two parts similar to that shown by Ian J. I have not had chance to refer to the book before writing this but could it be that the design in the book is the modified version. The only other change I can remember is the variation on the stops around the perimeter where instead of T slots there are a series of tapped holes. The stops themselves are made with adjustment slots to cover the range between the tapped holes.

                          regards Martin
