Am I understanding you correctly and the material you want to bend into a tight 90 degrees shape is 5/64 round? If so go ahead and heat to cherry red and bend. It can bend in the annealed state, but it will spring back to a certain degree, you have to overbend it, If bend is 90 degrees you have to go over that. Heat to cherry red and bend. Use a piece of steel the width you want the bends that are close to each other, ie. if they are 3/16s apart use a piece of 3/16. Once bent quench and see if it isn't "springy" enough for you. You might get lucky. I used to do it and I usually had the spring I wanted, just hurry and quench. For rod that small a simple torch is good enough to get you there. You can do it surprisingly fast. If you have some extra material experiment.
I was just a tig welder and sheet metal fabricator and they gave me these jobs. I just did it as fast and as simple as I could. If it works, it works. I personally hated making springs, but I will say if they were small I just used a torch. If it's wrong a quick anneal and do it again.
