re oldoberon post 1420
Agree the ' H" shaped piece is not an obvious or likely part of Jackscrew assembly. even so it appears to have " mouse ears " with holes for some sort of round strut or pin - which may have been part of a temporary support structure during factory assembly. I'm just questioning the lack of damage to parts which ** seem** to be designed to hold or align some sort of pin(s) or round bar.
And why no pics of Jackscrew parts/assembly ? perhaps not yet found ??
