Batteries are done, compressor is running like a dream, adjusting the bollard system,
Rising and lowering the bollards is controlled by this sliding tooth rail, which is driven by the antennalift using a sprocket.
He used bowdencable to transfer the motion to the levers which on their turn lift the bollards, the lever at the top of the picture is in the lowest position, which means bollards down.
This is the highest position, so, bollards up, the trick is, find the softspot where the bollards retract enough and show up at the highest point without creating mayhem at the mechanism.
The bollards self are gravity controlled, so they go down as the levers stop pushing them up, trick is to clean those tubes in which the bollards run, so the slightest motion will raise or lower them.
This is a teaser, Type XVIIb is on the bench, still have to play around with the bibers, even small boats need maintenance, when done i can turn my attention to the type XVIIb, stay tuned.
