I just went for the home depot 3/4" plywood path for the frame with 3/8" threaded rods (cover the rods with plastic tubing)
for springs if you want to produce a known force you need what are called "closed and gorund" compression springs. These are perfectly flat on both ends and have designed compression rate so you can literaly take the specification and by using calipers set them to just what you want.
sometimes you can find engineered springs on amazon, but most likley you will need to go to a spring store such as https://www.thespringstore.com.
