      Hi

      As you have found, they are close, but there is enough meat in the taper for them. It needs carefully measuments when turning the boss, I nearly made them too small and had the same problem.

      Fortunatly the tapered wedges cover any viewing.

        Yes they certainly are close but as you say due to the taper there is plenty of meat for the screws to hold them in.

              Managed to get the Fly wheel locking collars completed and could not resist a part dry fit with they in place.

              I have been putting off cutting a test tube to complete the oiler for the engine. So I tried to use a glass tube cutter which failed, and it shattered, so a good clean up and vacuum got rid of the broken bits. Next I wrapped the tube in some masking tape (I have about ten tubes as that was the minimum I could get at the time) this was gently gripped in the lathe yet strong enough not to slip, a Dremel was used with a small diamond disk and a short section soon parted ways from the tube. This section was rubbed on some very fine wet and dry paper to get rid of any sharp edges (With the tablets I am on if a cut myself it takes forever to stop)

              As most of the parts were already made from brass, the only other part was the control needle, which is from silver steel (tool steel depends on where you are in the world). This needed a point on one end and then cut to length and fixed into the top adjustment piece.

              The complete oiler ready for the engine once completed as there are still bits that need making. Without measuring it I would say between 1 1/4″ to 1 1/2″ tall.

              A question about the oiler if you make your own what do you use to seal the glass tube to prevent oil leaks

                A couple of models I have made supplied cork “washers” about 1/32″ thick. But gasket paper would probably do as would liquid gasket, you can get a clear one.

                      Glad you are enjoying this build. Things have slowed a little as one part I am remaking for the third time down to my silver soldering I have followed numerous people and still managed to stuff it up, I will get there in the end.

                        After two failed attempts at the governor assembly, I manage to silver solder the two arms on and now happy with the outcome.

                        Now onto some other small parts and a base for it to sit on so that I can attach the flywheels.

                          After making some pins I am able to do a test fit of the governor assembly hopefully this makes a little sense where thing go
