Yeah that’s where I’m headed at this point, to much weight and to much to risk. The ripper has a nice flat plate at the bottom on both side if the frame mount. I’m hope to crib there and then midship and then also both corners under the radiator. Planning to remove the track frames so I want to have access to the bolts at the rear to do that. I got a fair amount of access to hemlock here in the northeast… if not it will be some sort of a hard wood or I’ll cut up some timber mats.I use 12X12 square blocking oak would not trust those
I definitely appreciate your opinion, half say use them. Hard to disagree because I can tell you those pieces are about 24 inches in diameter and very heavy. Plus a very hard wet wood. The other half say don’t. Using some cribbing before (6x6 and 8x8) I can tell you those pieces I have are a lot heavier. Gonna take my time and find a safe way to do it. Might might try to use some of these and also do some horizontal cribbing as well like you mentioned.nothing wrong with those if you can square them up and use horizontally. If they're on concrete, I might put the ripper on them vertically if the base is wide and won't dig in to split. I wouldn't put the whole thing on vertical blocking, only one end if the other end is solid on the ground. I'd prefer elm or cottonwood if it had to be vertical. I'd use any hardwood over just about any softwood, but I don't have much experience with hemlock.
