I have decided to build a hydraulic thumb for the backhoe on my BX24. I recently added dual rear remotes with the intention to use them to control a thumb. The 2 spool valve hooks up inline with the backhoe. Today, I mocked it up with 3/8” plywood. The upper mount will be welded to the dipperstick.

I think you'll find out very fast that the rear remote don't work very well for BH operations, trying to grow another hand and arm to run it, is pretty hard to do.
You would be very easy to add a Electric valve that that is controlled by a button on a BH joy lever, that would keep your hands on the controls, not trying to reach behind you to run it.

I am sure it will be a little awkward but I am mainly just doing this so I will not have to climb off to adjust the thumb like I do with the manual thumb I have now.

NICE !!!! Great thing about wooden prototypes is that if they don't work, they can heat your garage. Whole lot easier drilling wood than steel, let alone all them teeth !! CLEVER ram 'in AND out' locations !! I'd like to 'borrow' that method please !

Saw a TLB that had 2 'saw toothed' plates bolted onto both sides of the boom. He could easily grab and hold onto 20' lengths of 12" culvert.
Seems like a simple, easy,cheap method. If there was a market it'd be quick to CNC the parts.

I ordered the cylinder and it should be here tomorrow or Wednesday. The upper cylinder mount is made and ready to weld to the dipper stick. A friend drew up the thumb plates for me and he is going to see if his friend can burn out the pieces on a plasma table.

Thanks
The pin is 1 inch cold rolled steel. Cold rolled has a single shear strength of 40,000 psi so the 1 inch pin in double shear is good for roughly 62,000 lbs.
