Re: rod-mill project - "mains" electric motor advice

I've been asked if the rod-mill is portable - ie. can it be slung in a
car and taken to where there's some minerals actions?  That is how far
it's gone.
The answer is yes just about - but nowhere near as much as I'd like it
to be portable.

That's typical of development; the first prototype is arranged to be easy to build and modify, when it works it prompts requests for repackaging, and perhaps to make it look like other commercial products. The Segway went through around a dozen revisions before its release. Your welding skill gives you a jump ahead on this.
I learned to work sheet metal and bought some basic equipment so I could make products presentable. It helps to design heavy equipment as portable modules that automatically align when reassembled, perhaps with dowel pins. If you use two opposed screws to align something a locknut on one is a reminder to loosen only the other for disassembly.
A guide to drill and tap straight is very useful when you add fasteners to connect the modules. It can be as simple as a block with drill-sized holes, near the edge if you frame with angle iron. I prefer to drill one side and tap the other so only one side needs wrench clearance. I turn the bolt end pointed and a short section of the thread to root diameter to make assembling heavy sawmill and gantry components easier.
