Bolt-on backhoe thumb

Has anyone here installed a bolt-on thumb to a LS LB1100 backhoe?

I built one for terramite.
Next trip to my other place I'll try to
remember to take pictures.
Have a working design.
Just having difficulty making it stronger.
The back jaw has a lot of force. Bends
metal like its butter.

I put a homemade one on a mini excavator using a farm implement cylinder but I have to be careful or it will bend it like a pretzel. An original thumb cylinder has a built in pressure relief valve inside when to much pressure is applied with the curl bucket it will just shove the cylinder in instead of bending it.i mainly use it to hold firewood off the ground while I cut it up
