@theluthier @thecabbagedetective Thanks, my goal here was to do modifier heavy work to get used to them see the changes and see how far could go with them in 2.8 at the moment.
Sadly no spiral curve atm and could not convert a spiral I did to curve for the handrail so could not use that, the model there with mods was specially good to set up the volumes I was going to use and the position, and then worked o nthe detail, going to update the first post with the current update
