Re: [RE-wrenches] Slow clocks

The way I learned to set gen set rpm's about 25 years ago was with a plug in
clock with a sweep second hand, and when the clock was good we had 60Hz.

Here in American Samoa the electronic clocks always run fast, a few minutes
gained every other day due to high frequency issues (65+Hz) that plague the
Island. The local power authority keeps the diesel generators cranked. 

 

Hope this help a little.

Re: [RE-wrenches] The big valley

2011-04-05 Thread Jeff Irish 
A similar story... we were recently called in to fix roof leaks certainly 
caused by one of our roof systems.  The homeowner was understandably upset with 
water stains on the new ceiling drywall of the old house they had just moved 
into.  Looking in the attic, we could see water stains and even moisture drops 
on the underside of the south roof... and also the north facing roof and the 
glass and frames of the attic windows on the east and west gable ends.  Seems 
the contractor had not installed a vapor barrier between the conditioned second 
floor and the unconditioned attic, and this being New York in the winter, warm 
moist air was rising into the cold attic and condensing everywhere.  But we 
were the first ones called, not the GC.
Same moral: don't be quick to accept blame for a roof leak.  Investigate all 
possibilities.

Subject: [RE-wrenches] The big valley

Friends:

Two weeks ago we had a torrential downpour in our area-- about 4 inches 
overnight.  I received a call Sunday morning from a client who we had installed 
a roof mount system for almost 5 years ago.  Their roof was leaking!

I hurried right over in the rain and sure enough, there was a leak right below 
one of our feet placements.  I inspected the caulking, and though it was not as 
pretty as I might have done myself, there was no apparent leak path.  Seeing no 
other apparent reason for the leak, I assumed it was through our penetration.  
I re-sealed the two penetrations nearest the leak and promised the home owner I 
would take care of all repairs..

That evening the client called and the roof was leaking again.  This seemed 
unlikely since I had carefully sealed my penetrations.  Upon further 
inspection, there was a valley near the leak and there was a tiny little sand 
dam in the valley.

The next clear day, I hired a local, large, well known, reputable roofing 
contractor to deconstruct the valley.  My arrangement with the client was:  If 
the leak was not caused by my work, I pay nothing.  If I caused the leak, I pay 
for everything, (including ceiling repair).  It turns out the valley was 
installed incorrectly with many deficiencies:  There was no paper in the 
valley, there were nails through the sheet metal, there was no mastic and the 
sheet metal was allowed to bulge up to allow a sub-valley away from the actual 
center of the valley and there was a hole in the paper right above the leak.

This same thing happened to us a year ago on a tile roof.  We were able to 
deconstruct the valley ourselves and the roofing estimator who had originally 
blamed us came right back over and verified we were not to blame.

I am relating this to the Wrenches list because any of you could have this 
happen to you.  The moral:  Don't be quick to accept blame for a roof leak.  
Inspect valleys carefully for debris.  Shingles or tile should not encroach too 
closely to the center of the valley.  Look for mastic under the shingles.  
Don't be afraid to lift tiles and look for water staining and debris trails.

Good luck out there!

Re: [RE-wrenches] Slow clocks

2011-04-05 Thread Kristopher Schmid 
Thank you all for confirming my suspicion regarding generators and clocks
and for the advice.  While i wholeheartedly agree that a 24/7 load like a
clock in an off-grid home seems rather foolish, everyone's line between NEED
and WANT falls in a different place.  I see it as my job to educate and not
to judge, as hard as that is sometimes.  Though i don't share their views, I
still put in systems for those folks believing in "TEOTWAWKI" (the end of
the world as we know it). 
 
Thanks again,
Kris
