Yes, since this was my first big welding project I started with the frame first. I purchased all the steel
cut to specific size. It was more expensive but I didn’t have any thing to
cut the steel at that time. I basically tack welded all the sections on and with a t-square and level checked it. The length is 16’ and is supported by the four tube steel columns I have at each end. This holds the weight of the logs. I usually lift the frame off the ground a few inches and level it before I start milling. I’m not sure what the axle supports since it only supports the sawmill frame. It was a left over axle my father had. I will post some photos of the saw. I built a chain saw mill thinking a band saw mill would be too difficult. After completing it I realized the band saw mill wouldn’t be that bad. That is my next project. I will send some more photos.
