Steam Turbine Model - Low Pressure Rotor V2

thingiverse

This is a beautifully detailed Low Pressure Steam Turbine Rotor. The STL files are in 1:18 scale and includes as much detail found on a real machine as possible. This model is designed to be assembled with glue. All parts except LP_bore_plug, 20T_blade, and 20G_blade should be glued together. Superglue + clamping for 10 minutes worked well for me. LP_bore_plug is designed to be removable with a slight friction fit. 20T and G blades are secured in place with a T-slot groove. The assembly was designed to fit 58 blades but I was only able to insert 55. Don't glue these in place because you may need to replace broken blades at some point in the future. See http://www.thingiverse.com/thing:1676760 for the rotor stand. See http://www.thingiverse.com/thing:1666208 for the lifting beam. This is V2 of the low pressure steam turbine rotor. Parts are generally comparable with Version 1. V1 is here- http://www.thingiverse.com/thing:1616343 Pros compared to V1: Greatly reduced part count Reduced printing time Reduced assembly time Reduced sanding time Reduced plastic volume Interfaces between sections are better hidden Cons compared to V1: Some realism is lost. The radii between stages have been changed to 45° chamfers. The chamfers have been kept unrealistically small in order to be printable without supports. For most people, this is not noticeable. Update 2017/04/23 Corrected scaling of 19T. Fixed 16G/16T to be mirror blade orientations.
