Exactly Steve the block holds the weight and the rod provides the push.

Thanks guys, that helps a lot. I have a large sheet of paper in front of me right now and trying to put this down on paper. I've got the Rod thrust bearing and a piece of nylon for the slider and I'm just figuring out the length of the push rod. Looks like it's about 8". What's the normal tip angle for the box to empty, I've used 45 and hope that's high enough. I think now that I should have waited before I ordered the gear motor. I only ordered a 34 rpm and it's going to be way too slow. Look like it would be better in the 150 rpm range. Anyhow, thanks again for the help as I'm getting more on track.
