Looks good. It's great that you have access to a mill. I spend most of my time at the shop on the mill and lathe making/modifying parts for engines. I wouldn't have built my Jimmy if those machines weren't available.

Oh, you are telling me. Without his mill, there is no shot at this. This is embarrassing, but I cannot believe I was actually thinking about milling it down with low grit sandpaper and a palm sander. Then, trying to cut out the hole with a damn hole saw! ignorant.
Jesse is an amazing fabricator. Big ups to him.
