Perhaps by mounting a pully on a postal scale and pre-loading it for 1 ounce (~ 28 grams).  
 
I looked at commercial wire tensioners or "dereelers" for coil winding and simplest mechanical ones look like a mixture of pinch rollers plus a spring-loaded pulley on a swing arm.  
 
The best picture I could find for one is at

Note the felt wheel at the lower left.  
 
More general stuff at:

Electronic closed-loop servo-controlled tensioners sit at the top in performance.  
 
No prices that I can tell, but I imagine that the cheapest ones cost hundreds of dollars. If you can get good results with felt pads or sewing machine guides instead of spending $$$, well...
