It is a good idea, as several here suggest, to play long tones with the bow. You also might want to add a couple of exercises playing short scale fragments like:
On the G string, play G A B C D C B A G, rest, repeat.
You can also try a chromatic exercise (no shifting here) using the notes:
G Ab A Bb Bb A Ab G rest, repeat.
Play these little scale fragments in eighth-notes between tempo m.m. 60 - 80. Use only a tiny bit of bow length (stroke), about 2 to 4 inches long, right in the part of the hair starting about 1/3 (of the bow length) away from the frog. You can concentrate more on the bow arm when you play something simple in the left hand. Concentrate on coordinating the left-hand attacks or shifts with the change of bow direction in the bow arm.
Remember that your bow sound is made up of three main factors:
Distance of the bow from the bridge, bow speed and bow pressure on the string.
By trying these short little fragments, you can get the feeling of playing eighth-notes with the bow. You should start with manageable little licks and scale fragments. This combined with the long-tone exercises that others are suggesting here should put you well on your way to Edgar Meyer or Paul Chambers or Slam Stewart-land.
