I have a buddy who is/has considered building a cocktail, and only a cocktail. In his view, a standup cab is - his words - "too big and bulky, takes up too much space". I offered to help him build one, if he would help create a template first, so as to pound out a few of them to sell for some side cash. Seems there's a market in our area for them, but I'm not sure if the ROI is worth it when dealing with another partner.
