Do you plan on mass producing frames..??
That's usually the reason for a jig .. or fixture, as most welders refer to them as ..
and .. you'll need a fixture for every different type and model of frame you make ...
People like Cycle One and others that use them day after day..... use them to make the basic fitment true in a short amount of time .. each time ...
That's the reason for fixtures ... keeping it all together every time ..

And if you plan to trust your fixture .. it needs to be very solid and well made .. That's the idea ... cheap and simple is not a consideration..

Unless you plan on using that jig for 10 or so frames .. I think its a waste of time ..

Build it the way you want it ..... then learn how to ride it like you own it..
