My husband has agreed to try to make a MIG welded hive stand. The problem is, being beginners ourselves, we're not sure what design elements are needed other than having enough room for 2 full-size hives and a 5-frame nuc. One club member suggested we have enough space next to each hive to place boxes during inspections. Is there anything else that might be useful? How far off the ground? How much weight should the stand be able to take?
