        Hi I have recently just started this hobby and a friend of mine gave me a set of BA taps his father had, he was happy to give them to me saying his dad would be happy they were being used.

        I think they are good quality, maker name is Lehmann, Archer and Lane Ltd, anyone know about them?? they are not marked HSS how can I tell??

          Jim,

          Unlikely to be HSS … but don't worry about it; they will almost certainly be very good!

            How can you tell if HSS or carbon.? Not just these taps but in general

                They were a good brand in their day, usually marked up LAL.

                Got quite a few old ones here but still good taps and dies.

                  I have a 1929 catalogue of Lehmann Archer products. In the preface there is an account of how the British Association Committee, in about 1881, decided on a screw thread system better suited than Whitworth (below 1/4&quot for instrument applications. This became our familiar BS system.

                  Mr Lehmann was approached by the Committee to produce the very first BA taps and dies in the range 0 – 16 BA. In order to do this Mr Lehmann had to "invent" machinery capable of generating the necessary, at that time, strange metric pitches.

                  The BA system came into general use in about 1887 after Her Majesty's Post Office Telegraph Department placed large orders for taps and screw plates.

                  So Jim you may have no fears about the ancestry of your Lehmann, Archer and Lane taps and dies.

                  By the way in 1929 a set of BA taps and dies 0 – 10 complete with tap wrench and dies stock contained in a wooden box coat 66 shillings = £3.30

                    I've got my grandfather's set of LAL BA taps and most of them are still usable.

                    'nuff said.

                      about 1 1/2 weeks wages in1929 for a skilled man, bit expensive in those days.

                        According to **LINK**

                        A craftsman's daily wage 1929 was 75p.. so a week's wages for that set of taps/dies.

                        …should have outsourced them to china…
