Dave,
I like that your linkage is above the dipper stick, out of the way. I should have considered that in my design. But at the time, I was not sure if it would be useful for digging...mostly "grabbing" stuff.
I am not sure about what
you mean by a resting place...you mean disconnect it? If so,
no, there is none with out pulling links. I found that with the
Gen 1 thumb, I dug with it in place, too, rather than getting
off my lazy a55 and removing it. It even came off in 5 seconds. I did
find the thumb actually assists in digging.
So that is good to know that it assists in digging. I have not tried mine out yet and I'm keeping my fingers crossed, hoping for the same results.
Yes, by "resting place" I meant a spot for it to fold back when not in use. But heck, if it comes off in 5 seconds, that is even better. Mine will need a few minutes to remove some bolts.
It's too bad you can't load up that video, I would live to see that thing work. But from your pictures, I saw how fast the jaw closes as it gets closer to the bucket.
Very cool Dave.
