Spent most of yesterday trying to get it sorted out. It’s closer than it was but not quite right. Here’s what your contractor saw looks like on the inside.

Just to the lower left of the bolt hole is the area I had to grind to get enough side to side adjustment from the trunnion.

1/8” seems to me like a lot for something to be off.

Hey Gary,

It does doesn’t it. I might bring it to a machine shop. I wonder if the guts are out of square.

I wish I was there to help. I’m pretty good at that sort of thing. Being an engineer has to be good for
something.

Hey John,

Before shimming the trunnions down from the table, did you check to see if the tie bars of the trunnion assembly were parallel with each other along their length? My understanding of how the whole mechanism works is that if you have (reasonably) good alignment when at 90 degrees but, not at 45 degrees, then your tie bars may not be parallel.
