Step 7: Base frame fabrication
In order to line up the frame properly, it is important to have a flat surface to work on. A table with a thick, steel top would be best. In my case, I used a table I made from an old door.
With the frame being so big, I was fortunate to have some help from my mate Kirk - thanks again! Another aspect of the frame/machine being big, is moving the machine when finished. As such, wheels are attached during this step.
The critical part of the phase is to have the top members parallel. I did spend a whole evening in order to get to the result I was after.
