Pond Boss Forums GENERAL QUESTIONS Pond Boss Should I let them off the hook and explain !!!

I think I know who the first poster is, and if so, he probably hasn't slept very well in the past year.

Just found this on the internet.

BTW, Cabbage Guy has tunnel vision and cant see past... (Your input here..............;-)

I am the cause of his sleep disorder.

I know that this doesn't fit into people with ponds, but ya gotta think by-products.

Fish create more regenerative waste than any other creature on the planet.

Engineers are funny...

A turntable microwave is simply a modern one with a rotating round "turntable" or platter.

It's a Tunable Microwave, not a turntable microwave. And in the Industrial Class, which means that frequencies can be adjusted to accomplish tasks at hand. What could you do with this...

Oh. Nevermind.




(Engineers are still funny.)

Something said by those who do not have to run by the rules I agree, engineers are funny confused, , crazy, , and most importantly, not worth that much since the 70's or earlier So the best engineers are the ones who do not have to engineer

Can't agree with you on the value of Engineers. They are the most sought after workers in the US and probably the world.

You can always tell an engineer... but you can't tell him much!

An Engineer can tell you how to tune a guitar but they can not tell you how to "tuna fish"

The funny thing I notice about engineers in bridge building is that they spend hours calculating every detail to the point that it is just strong enough to serve it's purpose then just multiply by 10...just in case.

"Hell for stout" "Good 'nuff" always worked for me... of course "just caulk it" and "can't see it from my house" has worked a few times too

In the aircraft business we engineers draw it with a computer, Measure it with a micrometer, the shop marks it with chalk and cuts it with a hacksaw.

For the record, I never questioned the value of engineers, I said they were funny.

Funny ha-ha or funny strange ?

I call them "slipsticks". I don't believe I ever did master the use of a slide rule.

How to tighten a bolt
Ryan's way: Spin nut on bolt then tighten.

Engineer's way (ODOT Spec book 2005)
513.20 High-Strength Steel Bolts, Nuts, and Washers. Provide high-strength
steel bolts, nuts, and washers conforming for all bolted connections including erection
bolts for cross frames and lateral bracing to 711.09.
A. General. Provide the Engineer with access to the work for observing the
installation and the tightening and checking of the bolts.
Determine the required bolt length by adding the value from Table 513.20-1
to the grip. The table values include an allowance for manufacturing tolerances
and provide a bolt length for threads to protrude through the nut. Add 5/32 inch (4
mm) for each hardened flat washer used and 5/16 inch (8 mm) for each beveled
washer used. Adjust the length, as determined by Table 513.20-1, to the next
longer 1/4 inch (6 mm); when installed, the end of the bolt shall be flush with or
project several thread lengths outside the face of the nut.

M36 47
[1] Total thickness of all connected material excluding washers.
Use bolts, nuts, and washers with a residual coating of lubricant when received.
Bolts, nuts, and washers without their original lubrication shall not be
used.
B. Preparation. With the exception of metalizing, galvanizing, and both organic
zinc and inorganic zinc primers, remove coatings from joint surfaces, including
surfaces adjacent to the bolt heads, nuts, and washers. Remove lacquer, dirt,
oil, loose scale, rust, burrs, pits, and other substances or defects that prevent solid

seating of the parts or interfere with the development of complete frictional contact.
Do not place gaskets or other yielding material between joint surfaces.
C. Installation. For each bolt, place a hardened washer under the element (nut
or bolt head) turned in tightening. If an outer face of the bolted parts has a slope of
more than 1:20 with respect to a plane normal to the bolt axis, use a smooth beveled
washer to compensate for the lack of parallelism.
If necessary, the Contractor may clip washers, at one location, not closer than
seven-eighths of the bolt diameter from the center of the washer.
During final assembly of the parts to be bolted, first install a sufficient number
of drift pins to provide and maintain accurate alignment of holes and parts,
then a sufficient number of bolts tightened to a snug tight condition to bring all the
parts of the joint into complete contact. Replace any bolts that were installed before
installing drift pins. Before releasing the member from the hoisting equipment,
fill half the holes with drift pins and bolts tightened to a snug tight condition
in at least 50 percent of the holes (preferably, half pins and half bolts) but use at
least two drift pines in each flange and web of each beam or girder. Install bolts
starting at the most rigidly fixed or stiffest point and progress toward the free
edges.
Use cylindrical drift pines that are not more than 1/32 inch (0.8 mm) smaller
than the hole diameter.
Bolts are snug tight when an impact wrench begins to impact the nut or when
a man applies full effort using an ordinary spud wrench.
Install bolts in the remaining open holes and tighten the bolts to a snug tight
fit, after which all bolts shall be tightened completely by the turn-of-nut method.
Where difficulty is experienced with the fit of the connection and the bolts
are used to draw the elements into contact, check all bolts in the affected portion of
the connection for a sustained snug tight condition.
Replace drift pins with completely tightened bolts only after all the remaining
holes are filled with completely tightened bolts.
Do not field ream holes drilled full size during fabrication.
After bolts are snug tight, the wrench operator shall match-mark the outer
face of the nut with the flush or protruding portion of the bolt using a crayon or
paint. The Engineer will use the match-marks to determine the relative rotation
between the bolt and nut during final tightening using the turn-of-the-nut method.
Commence tightening at the most rigidly fixed or stiffest point and progress
toward the free edges, both in the initial snugging up and in the final tightening. If
required because of wrench operation clearances, tightening may be done by turning
the bolt. If used, provide impact wrenches of adequate capacity to perform the
required tightening each bolt in approximately 10 seconds.
Do not reuse galvanized A 325 bolts. Re-tightening previously tightened
bolts that became loose by tightening adjacent bolts is not reuse.
Follow the additional bolting requirements in 513.26.
D. Bolt Tension. When all bolts in the joint are tight, the minimum bolt tension
for each bolt size is shown in Table 513.20-2.
TABLE 513.20-2
Bolt Size (inches) Bolt Tension[1] (kips), minimum A 325

Attain the bolt tension specified in Table 513.20-2 by tightening all bolts, the
applicable amount of nut rotation specified in Table 513.20-3 by the turn-of-nut
method.
Nut rotation is relative to bolt, regardless of the element (nut or bolt) being
turned. Tighten bolts requiring 1/2 turn and less within ±30 degrees and tighten
bolts requiring 2/3 turn and more within ±45 degrees.

Poor Theo!

I dont do tool stuff anymore. I have burnt my butt off trying to burn thirty foot walls of honeysuckly, let my little baby kubota go swimming off a dam cave in and while running have it lifted pulled out of water over the clutch peddle, it sure steamed, and almost neutered myself with a belt sander. The stories go on, but thats enough to get an idea.

But as my memory serves me there is a tool when inserting sparks plugs and or other parts of vehichles that tells you if you tighten something enough. Also little thing-of-ma-gigs that tell you if the gap in a spark plug is correct.

My lack of engineering/machanical skills tells me how important engineering/machanical skills are.

That said they do have a kind of out there somewhere look to them, but being someone that is considered a bit weird myself that is just an endearing trait. Besides us people who had past lives in Latium need to stick together, even if one of us lost our memory of old Latium with medieval depraved debauchery in France. Who doesnt like an occasional drunken orgy!

Citizens of Rome/Citizens of America unite!

No requirement to prove the torque wrench calibration is within the required specifications and time interval? No forms to fill out to prove correct bolt acquisition? You highway guys are a bunch of slackers.

My boss' boss could give you procedures that would slow ODOT down to the point where they would have a 6 year backlog for shovels to lean on.

"No requirement to prove the torque wrench calibration is within the required specifications and time interval?"

Certified to be balls on, dead accurate by the National Standards of Weights and Measures. Or something like that.

My Cousin Vinny

Theo they require all that too. What I posted barely scratches the surface. Our Skidmore must be calibrated annually as well as our impact wrenches daily to the specific bolt sizes using the Skidmore. If you change bolt sizes/lengths or add an extra washer you have to recalibrate. Then you have to double check with a calibrated torque wrench. All bolts must have certs and in some states, like Indiana, samples are taken at the jobsite to make sure they meet spec. You may only replace 2 bolts but they'll sample 5 even if they just sampled 5 from the same lot on another job the week before. You are right about being backlogged due to the specs. I had a job where samples were taken on the jobsite while bolts were being installed and sent to testing and then two months after the job was complete, they called and said they failed testing. Fortunately for me they had tested them to the wrong spec and our bolts were fine.

We get all the goverment we pay for.

wasnt there a thread about how a Pondmeister would change a lightbulb , kinda like this/.

Might want to change your dance, It's getting old, and has been a bit gross. Thats what I think.

The McButterpants Ballet is an acquired taste...

Fat McB noted on another thread his disbelief at being our forum comrade for 2 years now. It's been a good run. Unfortunately, 24 months of the 24-7 FMcB aerobic ballet has seemingly resulted in zero weight loss. Perhaps it's time to escalate his therapy to the Dr Burger JD-7-paregoric regimen.

so youre saying I should mix in a salad every once in a while?
