Decided to add a couple things to the Chipper. I need a place to hold the saws, pre mix, bar oil and maintenance bucket. When I chip I always need a saw and holding it or having it on the tractor moving gets old fast. I had a length of 6x6 pressure treated and simply used some long carriage bolts to attach it to the frame. Once that was done, I plunge cut with the saw through the center. Drilled through the upper leg box beam in the center so no strength was lost. Bars are a ways from the ground so shouldn't have any issues. Quick and easy to get and return. Won't have any issues with falling out either. On the other side I got some stainless angle iron and tube. Did the measuring and decided the size needed and cut triangles out of the bottom and bent them in. This is 1/8" angle so no heat was needed. On the mounting end, I cut a slit in the corner and double folded it. Cutting the triangles and bending gives you a nicer rounded corner. Just weld the edges where they meet and plenty strong.
I welded 2 edges of the double fold and drilled a 1/2" hole to mount it on. Kind of tight behind the box and I wanted something clean for the tube rail mount. I tapped the tube and then welded a nut on with a bolt holding it all straight and in line. To mount, I inserted a longer length of thread all from the outside, then double nutted it. This way I can have about 3 inches of thread contact on the inside of the tube plus the nut. I cut 45's on the tube as well and then welded the joint. For the uprights, I used a angle grinder to cut a slot through the middle. I also drilled a hole in the middle of the tube so I would have a matching radius to weld it on. Had to keep it a little smaller and enlarged it to size with a carbide burr. End product should do just fine. This will make it a lot nicer.
