See nothing in Spruce catalogue regarding 6261 or EN19 !! The reason I ask is that for my "soft drive" prototype on my corvair I will have to machine the housing from 6261 since we can not get 2024 or 6061 here. Also, the prop hub/spline shaft will have to be machined from EN19 and not 4130 or 4140 since we do not get these two grades here. Once I am happy with what I have, I will import some 2024 or 6061 as well as 4140 for the hub/spline shaft. I just need to know if the ally will be up to the task. I am not too worried about the steel as I know of a few planes flying here with EN19 hubs on VW motors with many hours on them (Hi Serge). Mine will not fly in prototype form though untill proper materials are used for all parts.
