Need to narrow a 8 3/4. Have a good ground heavy duty shaft to use.

Looking for tips/feedback on how you all made the bushings for the third member and the housing ends. In particular, looking for the clearances between the shaft and the bushings and the clearance to the housing ends.

Does anyone have any pictures?

In addition, any tips would be appreciated on the sequence and precautions to minimize warping. Need to weld the perches on along with the back brace.
