If mine was mounted on a thinner bench the handle would drop to near vertical before the linkage stopped it. I have enough wood chiseled out behind the linkage end of the handle to let it cam over just a little. The wood it is mounted to is the stop.
There are times I say life can not be fair because the Rock Chuckers I have been dealt have limiters that control travel . You could remove your press from the top of your bench without effecting handle travel. The toggle contacts the linkage and stops travel of the ram.
I am guessing I am the only reloaders that has figured it out. The linkage banging together pushes the ram back at the bottom and forward at the top.
I was using one of my Rock Chudkers when suddenly and without warning the handle travel changed. I said to my 'self!' "SELF!"; "That is not possible!" and then the ram hit the floor,. I called RCBS, they said they would send me a new one and I asked :A NEW WHAT? The said a new ram and I thought that was very nice.
