Thank you for the kind words!
- What type of wood did you use for the corner posts? Are those also walnut?
Yes, walnut for the corner posts. Apparently getting a true 4x4 walnut post is difficult, so these are actually three pieces of walnut glued to make a 4x4. You can see the individual boards if you look closely at some of the pics.
- What was your thought approach on the top (why you chose foam insulation board instead of utilizing the chest freezer's top)?
Man, where to start (I had LOTS of thoughts). First and foremost, I wanted the whole piece to look like a beautiful piece of furniture. Most of the design elements flowed from this desire. I felt like directly attached the wood top to the base cabinet with hinges attached to both, gave me the best shot of achieving this goal. Not to say it couldn't be done with the freezer's original lid, that's just not the route I/we chose. I'm not up to speed on the methods of attaching the freezer's lid, but the first thing that comes to mind is using lag bolts through both the lid and the wood top...I didn't want exposed bolt heads. I wouldn't trust glue between the two to hold the wood top, it weighed about 50#.
- Did you add a collar to the chest freezer because you needed the extra height, or because of a desired tap handle / bar top height, or?
A little bit of both. We wanted the height of the top to be a comfortable leaning height (imagine resting your elbow on it while conversing with a friend). Plus we needed a bit of extra internal height for the CO2 tank. We used a 2x4, which fit the bill perfectly.
- Did you have any thoughts about future-proofing this? (i.e. if the chest freezer dies and had to get another, would it be easy to find a suitable replacement that fits the cabinet)
The thought only briefly crossed our minds. It actually would be easy to swap out the freezer since it just drops into the cabinet. Obviously you would need to find a freezer of roughly the same size, but there's a decent amount (at least 1/2") of clearance around the perimeter of the freezer, so I wouldn't expect finding a replacement to be impossible. If you're worried about this, you could easily make the cabinet just a bit bigger to give you even more buffer.
- When you talk about a "reducer", is that the piece that is matched to the pipe and screws into the pipe-elbow, or something else?.
Correct. The piece that sits between the faucet and the pipe elbow. It's proper name is a "bushing."
