I am starting this discussion for those who wish to share ideas with those who have built or operated the 3″ Allchin. I am part of a group of 5 chaps in South Australia who cooperating as we each build a 3″ Allchin. We are using a steel boiler with an OD of 220mm which makes it slightly larger than a double scale Hughes model. Otherwise it is twice the size of the Hughes 1 1/2 inch model.

We have built most of the major components and are now working on the “fiddly” bits. I would like to make contact with other 3″ Allchin enthusiasts, and in particular at this point of time, anyone who has a good design for the safety valve

to give a crisp “pop off”

Ralph post this on Traction Talk Forum (Model Engines section) at least one of the regular posters has a 3″ Alchin and another a 5″. There are also a few members from your part of the world
