I've been wanting to make one of these for a few years as I use the pallet stacker (with a wooden pallet) as an aerial work platform for my taller projects. It can be fairly sketchy to work on. The stars finally aligned where I had material in stock, some time available, and I'm moving shops so I'll be doing a lot of high work (lights, wiring etc). I welded castors to the base so it can get rolled around the shop easily. I used an old receiver pin with cotter pin to secure the gate. My welding area is way too small so I had to make this in the wood shop. Tomorrow Il blow everything out the shop to try and remove all grindings etc... I'll probably paint it at some point
