You don't need it
Before CNC people made some pretty intricate stuff. CNC allows you to take a drawing and build it to an exacting standard. For one off stuff, your faster just building the damn thing. It is when you need to make 2 or 2 million that CNC becomes your friend.
Some steel, some washers, a bit of welding and you can build a prototype, and bit more welding you can make it solid, and bit of grinding you can make it pretty.
Or lay it out, go to one of the 3D print bars, print out your rapid design prototypes and test fit it and get the design right. Print the final in PLA, and use it to build a sand cast, melt down some ingots and pore the thing, and from their finish it up, with a step drill. Once you have that done, find someone to print the thing in metal. SLA will do the same thing, works like a champ, and very little final cleanup needed.
There are people who will do the run if you can make the design. Some times it just costs you a
If you want to DIY it, I respect that, look for a place that is setup to rent the tools. We have a place in Cincinnati called the Manufactury, wood working, Machine Tools, and some heavy 3D stuff, I know they have a similar space in the Bay Area as I have seen them, while working in silicon valley. I fly in and break shit, rebuild, make it better and get the F out. I can't take the Bay Area Pirus gangs
Should be something in your area,
like the UrbanWorkshopLots of ways to do this, you just seem to be hitting the brick wall over something that is trivial in the other scheme of this build. And don't feel bad we all run into that wall, just trying to pull you up.
