What are the rest of you folks doing to keep from putting holes in your cants with a cant hook? It has to grip. Had some success with just a board behind the ends but lots of time it slips. Perhaps modify the hook end with a steel 2x2 square that would have a rubber cap?
Sorry but that's how they're designed to work. If I am worrying about holes in the boards I hook it at the very end of the cant where any residual holes will likely get trimmed off anyway.
That's what I do, as well. It's not often with hydraulics, but sometimes I have to give an odd shaped cant a little help.
I wonder about making a replacement hook that has a flat metal pad with a few short spikes on it for grip. If the pad were mounted so that it could swivel to lay flat against the surface of the cant, it seems as though it might work. The several shorter spikes would give some grip, but the flat pad would spread the load and prevent them from penetrating very deeply.
you need a rubber band wrench. But in a 60" version with nylon strapping. :)
This design uses hard rubber roller skate stoppers instead of points...
I have not made a prototype yet.

Thanks to all the ideas.
Take a look at the pads on this grapple;

I wonder if I could slip these onto someone's slasher without him knowing :D

Those pads are like what I was picturing in reply #3, except I was thinking to add something to let them pivot a bit so they could lay flat against the cant. A ball & socket is one possibility, but I'm thinking it probably doesn't need to pivot left and right much, it just needs to go up and down a bit (I can't remember what you call the kind of joint I'm thinking about.)
On a virgin cedar for natural edge, not banged up already, rare indeed, try to hook in the end trim area that is often cut off.
