JD got me to thinking I needed to post an update. Quite a while back I asked for advice on ways to weld up a front bolster, to put a MF 245 wide front under my MH 101 Jr. My concern was that when I weld up a big assembly, things tend to move around. I got a lot of advice on how to V out my weldments, and how to move back and forth with my welds to counteract the warpage. So, what I did: I marked and drilled mount holes for the 3/4 inch base plate, which mounts to the cast front of the tractor. I was amazed that only two of the 9 holes took a little filing to get them all bolted up. Measure 3 times, drill once (grandpa taught me that). I thought long and hard about getting the two pivot holes with their bushings to stay lined up. I even built a boring bar to line bore them. I purchased a carbide-tipped hole saw in a size that would leave me some material to clean up with the boring bar, but when I got the holes drilled, they were JUST RIGHT, to press fit the bushings into. So I had no options to deal with warpage causing misalignment. At that point I decided that the first welds needed to pull the parts down solid, and stay aligned. My solution was to flatten the mating surfaces to be EXACTLY square to the mount plate, and then I drilled 1 inch holes through the base plate, as weldments. Two holes for each of the massive uprights, centered on their inch and a half mating surfaces. I fitted the two uprights, with the pivot shaft inserted in the bushings, and tacked them in place. I flipped the assembly over, and when I plunge welded them through the holes, onto the base plate, the weld shrinkage pulled them down hard onto the base plate. And the pivot shaft stayed aligned, and turned freely in the bushings. Then I perimeter welded the uprights for added strength, and added a couple of gussets that act as an anchor point at the front of the tractor.

It's not mounted on the tractor yet, because I need to figure out the full hydraulic steering, but this was a great success, mainly because of your great advice. Thank you, to all of you who lent a hand. steve
