Re: What??! A Belt drive??
			 
			 
			
		
		
		
			
			Belt drives do not need to be as tight as a drum. 
 
You have flanges on both pulleys so there will not be a problem with the belt tracking. 
 
If you want to change the ratio and  use a different pulley size then the belt size must also be changed. 
 
I do like your set up.
