Here is the construction process of my new sound cart, built by Brett Grant-Grierson.  He has built carts for Richard Lightstone, Joe Foglia, David Chornow, many for himself, and others.  It’s a (heavily) reinforced structure based on a Magliner vertical frame.  I’ll post more pictures as I mount the gear and get it ready for work...  Questions are welcome, phil@palmeraudio.net
