utilizing steering pivot allows for front and rear drive axles. this theoretically simplifies a geardown. could also allow for simple gear changing by moving motors and other adjustments.

'''The Control Cab Control Panel needs accommodation of:'''
*Power connection to Power Cube (3/4") - up to 4 Power Cubeconnections - let's do this.
*Case drain to Power Cube (1/4") - need to do 4 pairs if using 4 Power Cubes independently.
*6-spool backhoe valve - 1/2"
*2-spool motor valve - 3/4"
*2-spool foot pedals - 3/4"
*Totals
**[8] pairs of 3/4"
**[6] pairs of 1/2"
**[4] singles of 1/4" (just return)

==Sprocket Design==
How to design a sprocket - [[Image:chaindrawing.jpg|150px]]
 
[[File:chain.xcf|100px]] - source in GIMP
 
See also [[Chain Length Calculator]].
 
==Resulting Sprockets==
[[File:45T325bore.dxf]]
 
[[Image:sprocket45.png|200px]]
 
Sprocket with hub:
 
[[File:45T325bore1by8.dxf]]
 
[[Image:sprocketwhub.jpg|200px]]
 
Use this for cutting. This is just the hub backing plate:

[[Image:3hubplate.jpg|200px]]
 
Now the actual sprocket for cutting:

==Lathe Work==
possible motor for lathe [http://www.surpluscenter.com/item.asp?item=9-7467&catname=hydraulic surplus center]
 
doing a draft with motor mount and threaded rods that tighten to base with some pieces that can c-clamp to base.

drew a rough sketchup of the lathe. going to redo motor mount.

found this sprocket openscad thing on thingiverse

'''Download DXFs of the 6 parts here - these are 6.26 bolt spacing for these bearings - and DXFs have been corrected for 3/4" bolt holes, meaning 3/4" + 1/16" for CNC torch allowance. [[File:geardownDXF.zip]]'''
 
[[Image:geardownview.jpg|300px]]
*went back to the basics and cut out intermedate shaft and using a quick attach module style mount.
**requires very large sprocket to achieve desired ratio
 
*need to change chain cover to accomidate flange bearing bolts sticking through.

added to the model a mount style with QA facing opposite direction from before
*shortened distance the 2-15/16 bearing hangs out
 
cleaned up some of the mounting and case holes
*not sure about where the best places are to have mount holes
