Well flying solo, has not worked out for me with respect to programming my VFD unit, so I have sought help from another more specific Forum.
I am being well looked after there right now, but there just seems to be a bug that we have not discovered yet which is causing several malfunctions or sorts.
Here is hoping the guys on that forum will be patient enough get me thru it soon.
For fear of this thread becoming boring while I sort out my VFD controller problems, here are a couple of pic's of my Ford 9" diff straightening and narrowing jig.
So far I have only compiled the alignment bar and control points that indicate whether the housing is straight.
The next step is to make up a stand where the housing can be held and jacked at certain points to get the straight alignment back.
This stand will also be used to hold the housing when cut and narrowed and welded back into its new width.
Again the alignment bar and centers indicate whether the exercise has been successful by showing that all is true and in line...
Tricky business.
I may venture later to building a support jig which allows me to transfer brackets from a different make and model diff and then weld them accurately onto a Ford 9" diff.
The Ford 9" diff is a very common choice as an alternative these days particularly because it handle additional HP well and has many ratio options as well as brake options and axle lengths.
This should keep me off the streets for a while now...
