Drilled & tapped a 3/8-16 hole and inserted a bolt from the bottom. My stand is constructed so that I have access from the bottom and can turn the bolts as needed. I would have rather used fine thread but without using an insert it'd never happen in this material.
So...now we'll see if it's easier to square up!
And thank goodness for cherry pickers!
Sorry for the untidy state but I can only chase one rabbit
