Fence Alignment Changes when moved

[jadern]

I have a General 50-220 that I just assembled. After checking alignment of mitre to blade (within .003from both mitre slots) , I checked the General T fence. Was heeled in about .020 so I adjusted to .003 heel out. Now for the problem. The intitial adjustment was made from about a foot right of the blade.The more I move the fence towards the blade (left) the more the heel out becomes. When I have the fence one inch from the blade the heel out becomes .010. Something must be twisted, most likely the box rail or hanger. Any suggestions?

Clean fence contact points, clean and check the rail for truth. Tom

Admittedly not familiar with a General 50-220, but know that on most Delta Saws that have cast wings if you do not carefully flush out the wings and table on the front side during assembly you can actually bow the guide rail enough to get variable alignment as you move the fence out.

Shim under the standoffs?
