I'm working on building my own follow focus but I don't know where to buy a ring for it....I was looking at cheap stores(home depot, lowes) etc...any advice? I'm trying not to spend more than $50 on a damn ring..
Not sure where you might find a gear that cheap, but you could always swap out the gear on the FF for a foam rubber wheel of sorts like the indifocus offers. Not sure how well it works but it might be a cheap alternative...
