I totally admit that i am over budget. I picked up a stainless steel bowl from the restaurant store. 18 inch, +/- 16 quart capacity blah, blah, blah.
The feet of the diving arms touch the sides of bowl every so slightly, then continue their motion with a 1/4" gap. 1/4" is about 3 and one half toothpicks width. That is in comparison to the one toothpick gap on the Artofex Diving Arm mixer that I enjoy as a foundation for this build. We shall see if the ship still sails....
