Thanks Ben

I thought Leimbach sold one but from memory it was pretty expensive. DSTI makes some hydraulic slip rings. I have no idea what they cost or if they would work in this application.

I have thought about how to make the swivel as well (for a long term skidder project of my own). I think you might be able to use some fins to turn the swivel housing with a hydro line into each side of the housing where the lines enter at an angle to push the fins with the fluid. Of course you would need some gears in there to do the actual turning and you would have to limit the rotation so your hoses to the grapple wouldn't get twisted. To do a true 360 degree swivel you would need to have a hydro slip ring for the grapple hoses.

Not sure how it could be done but one day maybe I'll give it a try.
