This week 181 had a UMA manifold pressure gauge fitted and repositioned Hobbs
meter into undercarriage lever void... It was an adventure...
First a new piece of panel plate was drafted, and this time rather than waiting
for pieces to be lazer cut stuff got 3D printed instead. Two pieces were
printed, the panel plate and gps pilot mounting.
Everything worked great; except the $75 ebay "NOS" uma gauge... it did not work
correctly... so the gauge was removed and dismantled for inspection. Inside was
found corrosion on the primary lever arm. So the arm got polished and unit
bench tested. Testing showed the bellows was leaking; a very ineffective
climb/descend gauge; opening the gauge and seeing the inside quality it is a
$30 piece of average; not a single ruby bearing anywhere to be seen; somebody
is making a gigantic profit margin... So in the end an auto garage vacuum
pressure gauge was fitted to extract data information with prior to swapping
out the 80hp to 100hp.
Now need to replace UMA gauge with a functioning unit; very dissapointing when
people on ebay sell something as "new" and it ends up arriving ready for the
garbage bin.
