So, I recently built a terrible ghetto mill, which is a cross slide table hooked to a rotary tool press. Now I have used setups like this in the past to make pilot holes and cutting slots and grooves into aluminum and brass. It isn't great, but it is cheap and I don't have much space.
My question really though is can I do more? For example, I would be interested in cutting some sight rails but, I am not really sure how I would go about doing that. Is there a specific tool that I could use that would cut that angle in one pass? In the past I have used the Dremel 9901 tungsten carbide carving bit and cheap amazon 1/8" end mills to cut small slots like the sort a wire detent would use and I used the Dremel 115 high speed cutter to make wider groves, or to slot things together. Is there a bit I could use to give me that sharp angle to cut sight rails?
Also, is there any other bit I should use to make better cuts? Like something that could do an okay surface finish? I am not totally ignorant of this stuff, but I only know exactly enough to get myself into trouble so any resources would be appreciated.
As to the specific things I am looking to do, it is add sight rails, add some wire detents (On a spare body so I don't ruin a current one lol), add some eyes, hopefully mill out some Delrin eye covers (though the complex geometry might stop me there), and mill a slot into a piece of alumium with two holes into it so I can make a foregrip extender. I know I don't have the ideal equipment for the task, but with a tap and die set, my ghetto mill, and a drill press I am hoping to be able to accomplish the task.
If there is some other task that I can do with my current setup I would love to hear it, like I would love a way to add barrel wedgets or make gas through stocks, but it all seems a bit hard to imagine how I would accomplish these tasks.
