This seems to be a way to mount them without any critical machining. I could put the compound in the head, insert the bushings and then slip in the tool holder shaft and let it sit until the compound sets it seems.
I think Loctite 680 ("slip fit retainer") is the cat's meow. In steel, it's stronger than a press fit. The data sheet shows it isn't as strong in aluminum (75% of steel) and takes up to 72 hours for a full cure, starts to set in 30 minutes. Heat it to 250C (technical term: smokin' hot) and it melts. I think it would work great.
