Is there more to a draft tower than just a metal cylinder with tapped holes?
I found a post on here from 2005 where someone noted they make their own tower by drilling into a metal cylinder but it took many hours.
And also, shanks are important to purchase (and not DIY) because they are set to the right sizing/ threading / hardware to just quickly connect a faucet, correct?
Lastly, how does the faucet attach to the beer shank? I notice the beer faucets have male threading… but I don’t see female threading at the top of the picture here
