This is linkage for the variable tank main valve.  I didn’t want to have the handle in the middle of the deck so decided to move the valve control somwehere else via a link system.  Initially I made a curved bar with a handle that went through a piece of angle bolted to the hull ribs.  It was “ok” and did work, but it awkward to operate, scrappy and I didn’t really like it.  I propped it into place where it would have gone for the photo (top picture). 

So, I remade another linkage which took ages to make and was a complete pain.  Again, its “ok”, but a bit hard to turn.  Some sort of longer arm  with more leverage would be better.  But it will have to do for now, I might remake it “some other time”.  It’s better than the first effort.

The middle picture is with the deck in place.  I had to router out loads of bits from the underneath and chop bits out of the bracing bars.  Took ages.  I am going to get some sort of round knob to put on the longer lever bar to make it easier to turn.

Bottom picture shows the through hull that it operates.
