I'm not an experienced machinist.(But I learn quickly!) I'd appreciate input re: a good lathe for home DIY'ers like me. I'd like to be able to turn aluminum,brass,mild steel and 3-4 inch maximum diameters. I want to be able to make threaded adapters for telescope equipment(standard and metric). I'd appreciate input re: tools and add-ons that would be useful. I've been to the library and researched the topic already, so please don't refer me there. I'd like the advise of others who actually USE(and not just write books about...) metal lathes. Oh yeah, this lathe will be in my basement and has to fit through a standard doorway without major disassembly. Price estimates would help. Thanks.
