I hope you dont mind some preliminary comments here.

1. its a great model , nicely made , with complete parts, holes etc.

2.for Poser , in my opinion thats overkill. Unless it can be dismantled, may models for poser dont model the bilt , or the bilt hole, but rather model a bolt head, and nut only. 

3. again in my opinion , there are parts that dont need to be parts, but rather you need parts with multiple material groups.

     example: the pump handle and grip are seperate obj files. They could be one obj with two materials.  alos the vaious axles and pivot pins could be a material on the main part, so lift arm, lift arm pin could be one obj and so on.

4. The cylinder, ram and lift arm all have problems in poser, they balloon badly. I can explain that later. Turning smoothing off has fixed it, or most of it. 

5. The figure wound up with one major material, so I changed the material name for each part from Material to Part-name. This means you may have several things that all would be metal but we can address that later too.

6. I need to either extract the geom from the cr2, it all got created as geomcustom and embedded, or just export the obj file. 

7. I am planning on doing the chain as a seperate figure.

At this early stage its looking good, I have it rigged but there are a few things that need tweaking.

Problems to solve:

Only 1 that I may need to discuss with Les and thats the setup of the cylinderr and ram. I tried point at , and they point off in odd directions. I dont see an endpoint for either part but that may be how I set up the heirarchy, and there are some changes or regroupings needed I think.

I will continue with it later tonight.

The attached pic is showing its present state as a figure, with some materials set.
