During this shut down we basically cleaned and re-tightened electrical connections.

Burned out Bucket

Took a few interesting photos at work today, thought you might want to post them on your blog. Pictures of what happens when 4000A, 480V switchgear decides to find other ways to ground...

Let me know what you think.

All I can say is I'm glad I wasn't there when it happened. I've seen a few things blow up in my day, and it puts the fear of God in me each and every time. It looks like it arced for a while (relatively speaking)

For those who missed the eclipse

Hey Scott I found some job pics you might like, might not, just thought I'd pass them on and do what you like with em.

Ill try to start taking more pics.

JOEL HUNTER AND KIRK WILLIAMS (3RD YEAR)

Brian Marsteller

Keep em coming Brian!

Scott

BISHOP IS BEAUTIFUL BUT COLD, THIS DOESN'T COUNT WIND CHILL!!

Brian Marsteller

BISHOP HIGH SCHOOL CAMPUS IS BEAUTIFUL!!

Brian Marsteller

HARD TO TELL BUT I THINK THE DATE ON THIS CORNERSTONE IS FROM THE 20'S

DALE RADELEFF WOULD LIKE THE MASONIC SYMBOL.

Brian Marsteller

WOW I CANT BELIEVE I DID IT, I SUCCESSFULLY ZOOMED IN, LOOKS LIKE 1922, THE BUILDING WAS

BUILT IF MY MATH IS CORRECT. WE SAW SOME OLD STUFF IN THIS BUILDING. THERE WAS SOME

BIG LUMBER UP IN THE ATTIC, IT WAS BUILT BEFORE GLUE LAMS!! SEND THIS PIC TO DALE R. IF YOU

HAVE HIS EMAIL ADDRESS.

Brian Marsteller

VAULT MADE UP BY KIRK WILLIAMS LAST SUMMER, PRETTY NICE WORK WITH THE

FOREMAN BIRDDOGGING YOU TO DEATH!!

Brian Marsteller

KIRK WILLIAMS AT BISHOP PINE ST ELEMENTARY SCHOOL REMODEL, THIS TIME IT WAS DAMN HOT!!

YOU MIGHT HAVE SOME FUN WITH THIS PIC AND PHOTOSHOP!!

Brian Marsteller

I DON’T REMEMBER WHERE THIS WAS BUT KIRK WILLIAMS AND I DID THEM, DATA GUYS ALWAYS NEED A 4 INCH FOR

THEIR LITTLE CAT 6 CABLE!!

Scott

i finally got your email address. i knew if i waited long enough i would get it in a forwarded email.... lol.... anyways here's some pictures of
me at work.
Doug Childers

We all have our hobbies, and Steve Kendall's is cars, and in particular custom cars. Presently he is working on this 1958 Ford Apache 3200.

This 1958 Chevy Apache 3200 truck will sport a 1955 front, and has a Chevy 383 Stroker motor, Mustang II front suspension with rack and pinion steering, replacing the original straight axle, Ford 9-inch rear end, Weld Wheels (15-4s in front and 15-10s in the rear), Tilt Column, and a 1968 Mustang tank mounted in the rear, replacing the stock tank that was behind the seat.

This photo shows the 55 front mounted on the chassis

Air shows are one of my favorite events to attend and photograph, so here is a compilation of different events I have gone to in the past.

Another Tilt-up for Gregg

Sorry Steve, my camera batteries must have been on their last leg, I usually have better pictures than this one, I'll have to do better next time.

This photo was taken at a tilt-up in Rialto during a tenant improvement project.

SCOTT THIS IS YOU AND I BENDING 4" ON THE TABLE BENDER, LIKE MY 3RD DAY IN THE TRADE.

WE ARE ON THE DECK OF SOLAR TOWER AT SOLAR II PROJECT, AUG 1995.

Nikola Tesla

Tesla Anti Theft protection

This is a simple Tesla Coil design. The neon sign transformer provides current to the capacitor which stores a charge. As the voltage and current reach their peak, an arc forms across the spark gaps which allows all the stored energy to transfer to the primary coil. The primary coil creates a magnetic field which is absorbed and stepped up by the secondary coil. The magnetic field in the primary then collapses and its energy is transferred back to the capacitor and the process repeats until resistance in the circuit depletes all the stored energy. This transfer of energy from the capacitor to the primary is called resonance and it's frequency is determined by the values of both the capacitor and the primary (inductor). For every arc, which occurs 120 times a second (one for every positive and negative sine wave) there are thousands of cycles of charging and discharging between the primary and capacitor, so not only does the Tesla coil step up the voltage, it also steps up the frequency as well. Tesla coils can operate in the range of 50,000 to 500,000 Hertz depending on how they are tuned.

The secret to creating the greatest output is in tuning. A person on a swing mimics a Tesla coil in operation. If you give someone a push they will swing back and forth until resistance due to friction causes them to stop. If you push them on every cycle the amplitude of the swinging will increase each time provided that each push is greater then friction which causes them to slow down. If you can time the arc in a Tesla coil to coincide with the waves in the resonant circuit, you will increase the output exponentially. This is done by adding or decreasing the number of turns in the primary, changing the value of the capacitor, or increasing the frequency of the neon sign transformer. In our classroom design, the easiest way was to use an alligator clip on the end of the wire to attach to the primary. Depending on where we attached the wire to the coil varied the size of the coil and therefore changed the tuning of the coil.
