Can't comment on that, but very interested in how you plumbed the hydraulic circuit for the thumb on the BH75. I did the hyd thumb conversion but cut it into the curl cylinder circuit with a solenoid diverter valve. Willing to share your approach?
Thumb switch 2.0
Mounting block slips over shaft and stays there with two set screws. Zip ties best thing I could come up with to keep the switch on the block
Mo' betta :thumbsup:
The hydraulic thumb on my Woods BH75 is complete and in-service! Could not have done it without the outstanding advice from this thread - especially DFKrug and Bumperm. The key was stumbling on a cylinder at Surplus Center that had the right 2.5" bore and exact same retracted length as the...
I'm obviously a total newb when it comes to hydraulics, but am learning that these cylinders are much lower-tech than I thought. Thank you all very much for the lessons!
So in the absence of the "driven attachment" stopping the travel of the ram (like the thumb grasping a rock), what limits...
So after reading this forum multiple times, I said to myself, "This is something I HAVE to do". I just got a new Woods BH75 with the mechanical thumb and I can appreciate how useful a hydraulic conversion would be. But I've got a couple challenges that I'd love some expert input on, keeping in...
