I used 2x6 for the frame with 2x4 for the uprights. Also triangle gussets in the corners to hold the 2x4 uprights. Also I made my uprights 2 different lengths so I could work underneath and on top comfortably. The casters I bought at harbor freight. Not sure if you have them up there in Alberta. I think 4x4 might be over doing it, the bare body doesn’t weigh much when it’s been gutted of the glass interior and doors. I’ll try and get dimensions and pictures later. Mine is in pieces since I need to find a place to store it or chuck it if nobody needs it.
