Are you asking how to plum the cylinders together hydraulically?

Curious why you're building your own?

The port on the rod end of one cylinder gets teed with the port on the barrel of the other for one line, and vice versa for the other. I would recommend installing pilot operated check valves in the lines to lock the cylinders, otherwise your bucket might be unstable. The valves are about $200 each. I've posted a pic of how I made mine work. There is a valve on each side.IMG_20160905_185724013.jpg

Hey Shimmy, any other pictures of your bucket? Looks pretty cool from what I can see.

Don't take a lot of pictures. Contrary to what quite a few others feel about SEC buckets, i have had good luck with this one. I think the addition of the lock valves would have stabilized the bucket acceptably, but the pin bosses on the original cylinders were all slopped out due to cheap Chinese steel. I had new cylinders built as large as i could physically fit on the bucket. I can lift the hoe up with a corner of the bucket now, and the cylinders do not move. The first pic is what the original cylinders looked like.IMG_20140825_170854078_HDR.jpg IMG_20160915_154714789_HDR.jpg IMG_20160905_185938.jpg
