Here is what I did.
I started by welding some angle at the top of the bucket to secure a 3pt carry all frame. 2 pins hold it in out of the goo and it is a breeze to take on in off. My dad promptly pretzled the carry all, so I made a heavy duty one out of some scrap in the back.
OLd mold board plow frames are great fork material. NOt too heavy, but very strong and long.
I welded some angle in the bottom of the bucket to stiffen it and to take the strain off the cutting lip.
I also like this set up as opposed to clamp ons (which can put aq major strain on the cutting lip) as the upright portion prevents logs from rolling back over the top the of the bucket and crushing me. It is also easier to install/remove
It has held up very well and every timber in my house has kissed them at least three times, from woods to mill to frame. Today they loaded some 1000lb+ ash logs in my truck.
