There has been some discussion over how the MHR-1 tubes are constructed. Based upon inspection of the MHR-1 in my possession, it appears to be cast aluminium parts. They are probably post machined to obtain the appropriate dimensions and finishes. One thought for Gary. If the parallax in pointer to surface is an issue, bend the pointer. Yes, I realize that is pretty dang obvious, but it will eliminate the parallax . There will be no requirement on how accurately the bend is performed, since the two pointers establish the relative placement of the two scales. Even if the pointers are twisted, the relative placement of the scales will still be maintained, albeit at a different position than some other Bygrave that does not have that twist in the pointers.
