Help with legs

hey guys,
really struggling with getting size and tone to my legs, mostly calf mucles. I train my legs once a week. (is this to little??) i do the following:
 
squats
weighted lunges
power cleans
weighted calf raises
leg machines
 
could anybody tell me weather i need to work my legs more often or more exercises etc??
many thanks! 

how many sets/reps?

As above what are the set rep ranges?

Is the rest of your body growing well and making good gains?

usually do 3 sets with reps ranging from 10-8

the rest of the body is developing ok and i know it takes along time for serious growth and results and i've only started serious weight work witihin the last 6months or so.

thanks

When I used to train in my teens (many moons ago!!) I had a purge on calf muscles to bring them up with my legs. It was basically 3 exercises for 3 sets of 20 each as follows:-

- standing calf raises
- donkey raises
- seated calf raises

Routine was done 3 times a week and not on leg day. I used to use it as a warm up to my main workout. Did it for about 3-4 weeks and gained alot muscle in the calf area which has stayed ever since. I recall my calves measured around 15.5 inches at the start and were 17 inches at the end plus a lot more defined. I then returned to a more normal routine of just 2 calf exercises at the end of my leg workout.
