    HP Compaq Desk Top Dream Machine

    I went on the NZ HP Compaq website & found this machine: HP Compaq dc 7800 Choose Intel Core Duo Processor E6850 or better depending on your budget. Choose 1066 front side ebus 4 GB of the fastest ram - important since the graphics card on this machine shares the system memory - this is how...

    Batch Plotting in ACAD 2004

    I lay out all of my production drawings in paper space and line up the layouts in order I want them to print,naming the model tabs by the Mark # of each part. Then I plot,"all model tabs" and the drawings come out in some absurd and useless order - 30 to 40 sheets of scrambled pages. In...

    Monitor Recommendation

    I just did replace my old HP Workstation with a new Dell, with an Nvidia 512MB video card, so I am OK there. I think that when I replaced the four going on five year old computer, I realized that the CRT was going on ten. Thanks for the recommendations.

    Monitor Recommendation

    Has anyone had experience with the Dell Ultrasharp 2208 WFP Monitor? I need to replace my ailing CRT. Not asking for promotion or sales - just useful review of its pros and cons for AutoCad.

    To rout or not to rout...

    A five axis laser will do all of the beveling you describe very quickly and efficiently. Parts can be drawn in AutoCad and converted to DXF files which the machine will read. The five axis laser costs about 1/2 million dollars, but shops that own this equipment will subcontract the work at...

    Pull-Out Rating for Concrete Achor Bolts

    Thanks for the info (and the humor). The 2000 psi concrete comes from the literature of both Simpson Strong Tie and USP Connectors. I belive they are stating how well their post anchors work in minimal conditons (i.e. 4" of embedment in 2000 psi concrete). Never mind all of that, I decided to...

    Pull-Out Rating for Concrete Achor Bolts

    I am looking for the pull out rating on a 1/2" anchor bolt in a concrete slab. The anchor bolts are conventional J-bolts with 4" or greater embedment in 2000 psi concrete.

    Lag screws through 5/8" Sheetrock

    Use a 1.5" or 2" diameter hole saw to cut out the dry wall. The pilot drill for the hole saw will work as the pilot for 3/8" lag screws. Then use stacked 1.5" or 2" diameter fender washers for the bearing. Make a template from 3/4" ply for the size of the ledger. Use it locate the holes in...

    Curved Stair Stringers

    Stay away from the MC's, they are terrible to roll, the web becomes concave and the flanges go out of parallel. Plate stringers work well - develop the helix in 3-D to get the flat layout, them water jet or laser cut from plate. The beauty of plate is that you can include in the flat layout...

    Structure inside larger building - Wind Load?

    I don't know if this will be helpful or not. In NYC we fabricated a metal and glass tower in a large hotel atrium (fully enclosed). We were advised by our structural engineer to use 15 psf. We have also been advised to use that figure on elevator lobby metal and glass partitions, but I have...

    Live load for museum floor

    I vote for 100 psf. Museums often change hands and function - one day photos the next sculptures, etc. Forklifts are common and not all operators are pros. I was working in the Guggenheim, NY, when a 36 W 350 was dropped on the spiral ramp during installation of a sculpture.

    Radius Stair Stringer

    Elliptical forms are very interesting to build. If you use any sort or steel profile (rectangular tube) for the stringer, keep in mind that rolling equipment for curving the stringer works only on a fixed radius curve. The work-around is to draw the ellipse in AutoCad, take one typical quarter...

    Radius Stair Stringer

    If this is an exterior stair, stitch welding can become an issue, allowing water to get inside the section. I have seen cases where the resultant rusting (rust is about six times the thickness of the parent steel) has actually jacked apart and broken the weld (this was in corten steel, none the...

    clamps design standard, procedure

    Is the tubing round or rectangular? Either way it may be easer to form the clamp members from cold formed bent shapes - this gives you the freedom to specify an exact diameter or rectangular cross section, since matching O.D. to I.D. is not easily obtained in stock tubing sizes. The bolting...

    non-bearing 35 foot tall partition wall

    The load on the interior partition is not necessarily 5 psf - could be 15 psf. How about large plywood sheets al la Sydney Opera House - maybe Glulam framing - hidden or exposed as ribs.

    Pull out strength of studs threaded into aluminum

    Lutfi & boo1 The threaded inserts are a good idea for a number of reasons. The step up in diameter increases strength (tho I am OK there). The other good thing is that the insert can be backed in and out slightly to allow the shoulder eyebolt to be in the correct orientation - this is easier...

    through bolt in brick masonry

    Another advantage of using an adhesive in addition to the bolts and plates is to keep water out of the system.
