Bondo... It's a good concept but it can only do smaller pieces .
Ayuh,.... Right at the end of the video I posted, he's splittin' a good 3' round,....
I started out thinkin' of goin' with something like yer's,....
I've got a backhoe, not a skid-steer, 'n not havin' to run an aux. hyd.s is a big plus,...
If I did yer design, I'd push to the operator, rather than away, or crosswise,....
I'm thinkin' one like in the vid. I posted, with a straight knife, no cross-knife, for splittin' the 4', 5', 6' stuff I get,....
Block it down small enough to get to my northern hyd.s 37 ton splitter,....
Last winter, I stood abunch of rounds, 3', 4', 5' on edge with the backhoe, 'n manually rolled 'em to the splitter,....
No fun,... I hate noodlin' 'em down to manageable chunks,...
