I have been asked to design and build a mobile platform for this drum rack for my son's high school band. The requirements are it must allow movement over grass (football field), needs to be stable to have a drummer stand on during the performance, be low to the ground 3-4" platform height, and break down for transport. I have some ideas but want to ask for input. If I do it the way I envision, it will require some welding, so anybody that could help me with that would be great. I'm open so give me some ideas. I know this is the group to go to for ideas so thanks in advance.
