The question that comes to my mind is "Why?" By the time you put F connectors on and adapters to RCA and then whatever other adapters you need to connect to your gear, you've spent more than it would have cost to just buy a premade 25 foot cable, and a lot more than a cable would cost to make correctly.
Also, in my experience, coax braids tend to fall apart. They were designed to have a connector shoved into them, not to be twisted up and soldered to a connector. The only way I've been able to successfully put a non-F connector on a piece of coax is to shove a piece of solid copper wire up between the inner and outer jackets (into the shield) and solder that to the connector. Even that got flaky pretty quickly, and thus, I've stopped even attempting to work with coax except with F connectors.
I just can't imagine trying to do this. You probably could get away with it, but the $5 per cable cost savings really isn't worth the hassle.
