I've been selling quite a few plate and wing set ups. Biggest PIA is having a way to hold the plate to make threading the harness quick and easy. Setting it on the bench works but not ideal. Trying to do it while holding it or laying it down is also a pain. So after some deliberation, design modifications, and gathering materials this is what I now have in the shop to do it. Made of 1 inch steel square tubing, base plate and gussets from 1/4 inch steel plate, rubber padding, a couple ss bolts, washers, and wing nuts. Coupled with a can of Rustoleum I now have an ideal way to hold it at a height that is comfortable to work with and very sturdy. Here are some pics. When you have access to a machine shop with a waterjet, band saw, welder, and people that know how to operate them it doesn't take long to make equipment that works to your specifications.
