Buggs67,
Here's my homemade brush forks I built about 10 years ago along with a jib boom, and a set of bucket teeth.
I used 1/8" x 1" x 2" tubing for the forks, and 3/4" plywood for the platform.
The brush forks are used every spring/summer, and are fastened with 3- 1/4" x 20 grade 8 bolts thru each side of the bucket.
The hinged plywood platform is attached to the top of the brush forks with 2- 1/4" x 20 eye bolts drilled and tapped thru the top of the brush forks.
The vertical wooden headache rack is also attached with 2- 1/4" x 20 eye bolts drilled and tapped thru the top edge of the bucket.
When I want the wooden platform up, I just use a bungee strap to hold it in position.
Hope this gives you more information to help you with your final decision.
