      The pipes are then silver soldered into the mounts.img_0030 (medium).jpg

                Time to make a stand for the engine.

                I wanted to make a carrier similar to the one used on full size engines so I

                thought I would put my new silver solder skills to use and solder some stainless

                pieces together.

                I made a simple jig to hold the pieces while I soldered.img_0035 (medium).jpg

                  After soldering the cradle it was put into a Citric acid bath for a few minutes then polished img_0036 (medium).jpg

                    Next I cut a couple of pieces of hard wood from some old door frame I saved.

                    The first piece I cleaned up into a rectangle and routed around the top , the second

                    piece I drew a rough outline of the shape I wanted and attacked it with a flap disc

                    on my grinder. It carved up much easier than I thought and just needed a quick sand

                    into the final shape before I varnish.img_0037 (medium).jpg

                      Quick test of the cradle to the rear of the engine.

                        I have given the stand a sanding and varnish , then mounted the engine.

                        You may notice the manifolds are now silver ,had some silvering powder

                        left over from a clock build so decided to use some on the copper manifolds.img_0044 (medium).jpg

                            Got a small propeller of EBay so had to make a prop washer for the crankshaft end.

                            Turned the profile from some alloy round barp1040908 (medium).jpg

                              Using a piece of tool steel ground with a chisel edge I cut the slot for the woodruff key p1040910 (medium).jpg

                                So the engine is now complete , unfortunately the carb I bought is not suitable so I need

                                to find a replacement. The carb I bought is a 'slide' carb and will not fit properly between

                                the cylinders so I need to buy a rotary versionimg_0065 (medium).jpg

                                    Excellent build log David, have just read all the way through with great interest and learned a lot from the work holding set-ups and the design, especially of the epicyclic geared cam drive and internal fan to stir the air in the crankcase.

                                    Many of the work holding set-up were especially interesting, this being an area where I have little experience – that proved invaluable.

                                    The standard of machining is excellent too, resulting in a lovely engine to be very justifiably proud of.

                                    Well done that man,

                                    Chris

                                      That was fantastic, have read from start to finish.
                                      Very impressed!
