I just built a set of bucket forks for my Kioti CK35. I think my next project after my brush rake will be a regular set of forks.
After a trip to the scrap yard I came home with 300lbs of rectangle and square tubing, some flat stock, some channel and a long piece of 1 1/2 steel rod. Scrap prices are down, (25 cents per lb) so I paid $80 for everything.
My forks probably weigh about 200lbs, which is a little more than I had planned on, but this also includes where I reinforced the bucket. The tines are 2x3 tube, 1/4" wall. The verticals that attach to the tines are 2x4 tube, 3/16 or 1/4 wall (I cannot remember at the moment.) These attach to the steel rod, and that attaches to the reciever hitches mounted on my bucket.
I hadn't planned on using so much 1/4 inch metal, but I found two pieces that were perfect in size.
I still have enough metal to almost finish the brush rake, so the real price for just the forks would be about $60, including the reciever tubes i bought for the bucket. Took about four hours to build.
My camera is busted right now, but I'm hoping to get photos soon.
