            Thank you Julian. It takes a big man to apologise.

              Whilst waiting for the storm to abate (referring to the weather) I was musing about a discussion which took place elsewhere regarding model loco building. A man was asking what is took to construct a model loco. Another contributor answered that all he had to do was to get hold of the works drawings, find a CAD technician and a 3D printer and hey presto he could then trot off to the foundry and get castings made! If only life was that simple. It helps if a knowledge of how foundries operate. A case to illustrate this if this motion bracket casting:

              The CAD model took quite a bit of figuring out.

              The pattern and core box for a combined left and right hand casting

              The casting straight from the foundry.

                Hi Ennech

                Are you still building the SAR 15F model?

                If you do can you please post again.

                  It's been quite some time since Eric's original development of these castings. I am, as far as I know, the only person so far to have built a model using some of these castings, so out of interest I thought I'd post an update.

                  I can't remember exactly when I took delivery of the castings but I think it was around 2016, but in fact it's been about 3 years building as it was shelved for various reasons for about a year.

                  Around the same time as I restarted the project, I learned CAD design and so for the remainder of the build I often didn't use the castings as it was easier to fabricate to ensure good fits and more detail. The wheel castings and cylinders were in the end the only ones to be used, with some modifications made to the cylinders to improve faithfulness to the prototype.

                  Only the pipework remains to allow it to steam. It runs smoothly on compressed air. Some photos attached and hopefully the short video uploads, let's see.

                    I would use the word impressive but that's not a a big enough word

                    holy smoke

                    Are you going to run this thing too?? edit yes he is

                    edit: I got the full set from the original website when it was shutting down because I thought the resource might disappear into a private hands black hole. It's all high end originals in dire need of updating into cad apart from a couple that were already done at the time

                    Great to see that this very advanced part of the ME community is still being continued

                      Thanks, yes I got the same Cd rom, really an incredible deal as that amount of drawings would be astronomically expensive from any other source. Amazingly enough though, it is still going and they are all still downloadable.

                        Good to see this amazing loco being built with such perfection, I remember them all to well waking me up at 3:30am charging past my military base in Kimberley.

                          As a final update, she's in steam and running nicely, looking forward to some public running in the summer.

                            Good day Andy

                            Can you please point me in the direction were I can purchase these loco drawings and if available in CAD format, so mush better.

                                How mush does the casting weigh about.

                                  The completed locomotive, although if you like detail, there is almost no end to the project. There is a lost wax casting in bronze of the vacuum ejector so if that can be made to work, all the linkages are there to the vacuum cylinders, which are also now fitted.

                                          Looks totally amazing, what an achievement

                                          Can you post any video links in this thread please

                                          one question

                                          How do you get it into the back of the mini metro and over to the running track?
