that should give you a better idea ,,, its just a starting point , but keeps things really easy to makevery quick sketch
well Ill look forwards to the pics , its nice to see how other folk tackle things ,,,Haha that's a pretty decent quick sketch, you're definitely a man of many talents!
I've just realised if I reduced the box section to say 40mm then the 10mm plate would have fit inside the pusher plate u channel that wraps around the beam and been an almost perfect fit but no point changing that now I've got some coming for £9 so I'll do what you're suggesting with the side plates and just use an extra short section of the u channel as got plenty left and that'll help reinforce the rocking around the rod pin if pushing a log with the tip of the plate accidentally instead of it being up against the beam.
Makes sense beefing it up since got a +10t cylinder so might as well make the most of it!
