My Opal dates from December 31st 1936 and as such features the worm and sector arrangement rather than the more familiar worm and wheel to produce angular motion. Opportunities for adjustment are therefore fewer since there is only one position for the sector whereas the wormwheel on the earlier boxes have 3 positions and can be rotated through 120 degrees. In his A7 manual Woodrow describes how to improve the mating of worm and wormwheel by using grinding paste to abrade the high spots and produce a fit that runs freely, is free from tightness with minimum clearance.
In the section on the 1936-1939 steering boxes Woodrow makes no mention of achieving an improved fit/clearance using similar grinding paste methods with the worm and sector. Does this imply that such an approach is a non starter?
Have any of you Ruby/Opal/Pearl owners significantly improved your steering by similar grinding methods - especially the minimising of steering wheel free movement ? Or are there other approaches to improve the steering? I'd very much welcome your comments.
