what do you think would be the best way to attach the motor mount assembly to the shaft that goes through the frame. I had thought about making it similar to an axle assembly. But I'm quite limited in space, because there is less than 2 inches of space between the wheel and the motor mount. there is going to be quite a bit of strain on that joint, and if I put a suspension system in, it will see a lot of action. I think a bushing would wear out very fast. So putting in some kind of bearing system is what I'm looking at. Any suggestions.

I see 2 ways to do this:
1. Have someone machine in places to install a pair of bearing races (like on a trailer hub) and use tapered roller bearings. Then machine the stub that mounts on the box to match (essentially a skinnier version of a trailer hub/axle stub)
2. Mount a shaft into the end of the pivoting arm (flanged shaft?) and put a pair of sealed pillow block bearings on each side under the box.

Use bushings and put them on a regular PM schedule to replace. Bushings are cheap. If you're not making a full revolution, bearings don't make sense.

Nothing specific project wise yet; but I have some things in mind. I'm still slogging through the tutorials.
I'm using 32-bit XP, and my biggest gripe is display hiccups for lack of a better term that I believe are caused by my video card. I'm trying to decide whether to get an ATI card for the current PC I bought before Win 7 arrived, or get a new PC. I got XP as Vista is a mutt with fleas. From what little I have to maintain on my technophobic wife's Win 7 laptop, I do like Win 7.
Now I hear Microsquish is coming out with Win 8.
I think what I've got here now, should work well. I took to tapered roller bearings on the inside and the outside of the motor mount and then put a 1.25 inch shaft through the frame and then thread the ends, and use a spindle nut to tighten it all down. The motor mount plate is 1 inch thick and each bearing is slightly less than 1/2 inch. So they fit in there quite snugly. I will be using sealed bearings which is not showing in the diagram. Let me know what you think.

one question that has been brought up, is if I will need some kind of mechanical locking system for the kneeling feature. The hydraulic Rams will more than likely creep down over time while driving around. Do you think I should be that concerned about it. Will there be that much movement.

How much do you trust your valves, seals, etc.?
Hydraulics creep. Some more than others. If it were me, I'd put some kind of lock... either an accessory hydraulic valve like they have on scissor lifts, or a mechanical lock.
