does it not work
as it is?
Bendong back, just where ot os noe, with a big adj. spanner wpuld work
. Not to damage thonge, put a bit pf lead plate in the adj.
I pnce "repaired" an expensove sextant
with lead voce and an adj spanner. The arm that held the mirror eas bent so far that ot was out pg adjustability.
The shop that had to check it and could not do that, could not belive it. the thong eas nearly spot pn over the whole range.
