Sorry, but you haven't really given enough information to get an answer on something like that. I'm sure that there are plenty of guys that live in the area that wouldn't mind taking a look at your situation if there were a beer involved for thier time and effort. Try a local Home Depot or Lowes if you can't find a real deck guy.

you might try a figure 8 knot, or a stopper knot.\n\nhttp://www.chockstone.org/TechTips/Stopper.htm

I would use a length of nichrome wire (see links below) stretched between a couple copper blocks. You could make some sort of pinch block out of the copper and connect a power supply to the copper. (or drill a hole through it with a set screw, tap a hole and us a pan head screw)  You will have to insulate the copper from the rest of the world so you don't short something out.  G-10 (a glass/epoxy resin) makes a good moderately high temperature insulator.  One of the contacts should be fixed and the other allowed to "float" and allow for changes in the length of the wire due to heating.  A spring could be used to provide tension or an air cylinder.  The power supply will depend on the length and diameter wire you choose.  If there is a problem with the electrical contacts heating up, you could run some cooling water through them.  Just drill a hole through it and 1/8 NPT pipe tape both ends.  You can plumb some water to it and it will keep the copper chilled.

Call SUPSHIP at Newport Shipyard.  I know it is a tamper shaft but each one is different size anymore.  Better yet call O5H at NAVSEA DC.  \n\nGod Bless You and The Southern People.

Better have a contractor look at your situation.  How high is the water table where you live?  Etc.

picture a water pipe that is 1/4 inch in size, and a water pipe that is 5 inches in size.\nWhich one can move more water?\n\nnow invision dial up and the small pipe and broadband as the large pipe.\n\nof course the use it to move more stuff.

Not sure this helps....there are other pages at this Portland Cement Assn site.  Browse around this site.\n\nhttp://www.cement.org/countonconcrete/Wall%20Systems%20Backgrounder.pdf

check with a local commercial architect. they sometimes have someone on staff for that or they would have some recommendations.\n\nand a company like this can do it http://www.barrdisplay.com/

3/4" Marine plywood: (shaped to taste hehehe!) add a little rocker....cover with marine epoxy...sand till smooth... paint.. whalla!!\nthen shuvit shuvit shuvit!!!!\n\n- good for flat water skimboarding! hikhikhik!!

I dont think you'd want a FOS less than 3.  Side friction on a pile is something that is not easy to estimate and is highly variable.  You want to be sure that you aren't going to have failure later because it could bring down your whole structure if one pile fails and you end up with differential settlement.

go to the hardware store and get weedwhacker string.  the plastic is just about the right gauage to hold the place.  be sure to sterlize it first.

2 3/8" steel pipe would be nominal 2" pipe which has an outside diameter of 2.375"\n\nThe weight per foot for sch40 is 3.653 lbs\nThe weight per foot for sch80 is 5.022 lbs\nThe weight per foot for sch160 is 7.444 lbs\nThe weight per foot for XXS (double extra strong) is 9.029

go to your local contractor and ask

The technically correct answer is to balance heat loss with various insulated wall thicknesses against the installation costs for the wall, insulation and the heating system. Add in the savings in energy over a period of time to come up with a balance between costs and energy savings. \n\nIn reality the practical answer is to look at standard building material sizes and use those to make a quick choice. The old standard was a 2 x 4 stud wall (really a 3-1/2" thick wall not counting exterior and interior finish). The next step up would be a 2 x 6 stud wall (really 5-1/2" thick wall) and this is in many places the current norm. The next stand stud size is a 2 x 8 thickness but that does not appear to be very common.\n\nWhen we built our current house, we got energy saving estimates from the local utility that compared various wall finishes and thicknesses with BTU's saved. I would bet there is similar information available from you local utility or on line.

So you've got the look-down angle and you can cut a piece  of scrap to check that that's right, then you scribe top and bottom on your scrap with a 1/2 inch or 1/4 inch inset so you can see what angle you need from top to bottom? This is the 75 degree that you are talking about?\n\nIf so then, when you invert (assuming the top and bottom faces are parallel) you still have a 75 degree angled cut don't you?   Why not just cut for the look-down, offer it up and scribe then hand-plane?

Yes, you can do it, but it will require iterations.  \n\n1) Convert all units to standard engineering units (feet, pounds, seconds).\n\n2) Set up the mechanical energy equation:\n(p2 - p1)/gamma = z2 - z1 + (f*L*v^2)/(2*D*g)\nwhere p2 -p1 is the pressure across the pipe (20 psi, but convert to lb/ft^2), z2 - z1 is the rise in the pipe (if any), gamma is the specific weight of water (62.4 lb/ft^3), L is the length of the pipe (50 ft), D is the I.D. of the pipe (ft), and g is the acceleration of gravity.  \n\n3) Now you have a problem: v is the velocity of the water, and f is the friction factor, which depends on v.  So, you guess a value for v, and calculate f from it.  You look up f on a chart (it's called a "Moody chart").  But you'll need the Reynolds number and relative roughness of the pipe surface to do that.  Then you try another v, find f, etc.  Or, you can try this:\n\nhttp://www.fluidmech.net/jscalc/vmd03.htm\n\n4) Just keep plugging in different velocities until the head loss (right side of the equation) equals the left side.  Then convert to volumetric flow rate.\n\nHey, I get 14.2 ft/s, 0.0774 ft^3/s = 34.7 gpm
