One of the things that an amateur turbopump builder will need is a gas generator. This has a lot in common with a rocket engine igniter, which is one of the reasons I'm currently building one (igniter, not GG) in collaboration with some of the other folks on Arocket. Once we have a working design I think a gas generator should be relatively straightforward. Alternatively, if HTP is one of the propellants the GG is pretty simple.
I just checked the aRocket archives and I see you've posted to the list, so no doubt some of this is old hat. Anyway, I think the place to start is with a proven gas turbine design and modify that into what will probably be a very poorly performing turbopump. Once you've learned a bit from the modified turbine you'll have a solid basis to build a higher performance turbopump. If you can build a turbopump you will have little difficulty in finding collaborators to work on engines, airframe, guidance, structure, etc.

Just got to wonder... lots of talk about how difficult it is to built reliable and efficient turbo pumps... lots of good intentions to experiment...
But has anyone ever succeeded in building a small-scale pump suitable for
amateur use, and who would be willing to share anything from a rough sketch
to a detailed blue-print?
