Here are some more pictures you were asking for sorry the base is dirty now i just smoked some shoulders and chickens
Anyways, i didnt cut it myself i found a local place to do it for me ( not to bad cost wise) i used option 2 on one of the pictures im glad i did because that was just enough room option 1 would of been to small so you might want to go bigger than option 2. Also in one of the pictures i showed you the screws and lock nuts i used. I just predrilled the holes and it worked out great i used 5 wheels placed an inch in and 12 inches a part mostly just eye balled to place them i got them at lowes here is the link http://www.lowes.com/pd_235587...t%3Drubber%2Bcasters
the nuts and botls are stainless steal and the base is 3003-H22 Aluminum Bright Tread Plate, .25 : (Width:27", Length:27
