Building the lower wood frame.
Starting with just a stack of cut wood the lower frame is assembled, wheels are added, top metal frame fitted, and then stained.
Building the lower wood frame in a simple step. I cut the wood one evening on the chop saw, put it together the next, and stained it on the third. Not too much can go wrong here if you follow the plans. The whole rig is very heavy by the time you are done and this frame has to carry it all. I initially thought that the 2x4s were over kill that it could be done lighter out of 2x2s. That would have been a mistake. At times I have had to stand and clime on the machine to get parts in place. I was glad the frame could take it.
Follow the plans and you will have no problems.
