Remi,
My long range tank has been returned. I took some pics to post on my
build website, but it appears that EuropaOwners.org is down again. So
I will pass along some numbers for you and will post the pics when the
site is again functional.
Outside diameter of tank opening threads is 2.55 in. or 64.77 mm.
Inside diameter of the cap threads is 2.5 in. or 63.5 mm.
This provides 0.05 in. or 1.27 mm of thread engagement.
The threads on the tank opening are not perfect and it can be
difficult to put the cap on without cross-threading. But once the
threads have been properly engaged, the cap screws on fairly easily.
Still, it is not a perfect fit. I would not trust the cap to not leak
should the tank end up on its' side or, worse yet, upside down.
My plans no longer call for the use of the long range tank anyway. My
wife has declared that there will NOT be any flight leg longer than
THREE HOURS no matter how long the Europa can fly on available fuel.
So the long range tank is now superfluous for my needs.
I'll let the world know when I am able to post further to
EuropaOwners.org. Not much work done in the last two days anyway.
Too durn cold the last couple mornings. It was 27F/-3C this morning.
And afternoons have been wiped out by other obligations. Perhaps I
can get some work done tomorrow as it is supposed to warm up a bit
before the next cold front comes through around Tuesday (with possible
frozen precipitation).
I need to put the covers on the door latch mechanisms, drill one final
hole in the brake lever to put the last screw in to hold the brake
handle on and do one final weight and balance. Oh, and complete the
final check list. I believe that's it and I can call the Mel Asberry
(FAA/DAR and EAA Tech Rep) to do the final inspections.
Check six,
Bob Borger
