    Is nogging really necessary for studs?

    Nogging is the English word for small pieces of timber (wood)inserted horizontally between studs. In Scotland they are called Dwangs and from your replies I believe you call them blocking in the USA. In Australia we also have short timbers called blocking used in other parts of timber framing...

    Is nogging really necessary for studs?

    Timber studs in Australia (& many countries ofthe world) are required to have nogging (dwangs) between studs at about 4'6" (1.35m) centres vertically. Their function is often debated. Is it needed to stiffen the wall against a concentrated load, to fix the wall lining, to prevent the studs...

    Pole Barn Truss Raising

    I know of a builder (here in Australia) who built all his roof frames on the concrete slab on ground. He installed all the concrete roof tiles except for a few and installed long-stroke hydraulic jacks (the jacks poked through the missing tiles) and raised the lot in one go. THEN he installed...

    Driving on the right

    Of course you can't believe all you read on the Internet (Sweden's changeover was 1967 not 1969). www.travel-library.com/general/driving/drive_which_side.html seems somewhat of an authority on the subject (after 1920 for half of Canada and about 1800 in USA).

    Driving on the right

    Let me add that I understand that Napoleon precipitated the change along with many notable improvements (like street numbers). Horse drawn traffic travelled on the left as proscribed by the Romans. But of course in pre-revolution France those in carriages were the aristocracy. The poor...

    Get me on track in/re trains

    It is interesting that you had many gauges in the USA as we had the same problem in Australia...but Mark Twain was not amused. The following is an extract from the Victorian Railways Web site. It seems not dissimilar to the US experience Early history Australia's railways were developed in an...

    Driving on the right

    Can someone enlighten me when the US & Canada changed from driving on the left to the right? (I understand that the US changed some time after the French Revolution.)

    Long Span Wood Trusses

    While I know you are looking for US examples there is an excellent collection of structural wood engineering information brochures called Informationsdienst Holz (German. One of these is Fachwerkbinder Berechnung Konstruktion dealing with what we call in Australia Architectural Trusses. Large...

    METRIC !

    owg With regard to road signs, I was in Ireland the other month and many distance signs are Metric and some still imperial. The Metric are white on green, Imperial black on white. No problem in the small Toyota hire car I was driving. All the display was LED... speedometer, odometer, trip...

    breakaway fence design

    Have done several designs based on the same principle but for bridge railings so not entirely applicable. Are you proposing that they fall flat on the ground or pivoted at the top? Is there a problem with the latter with a debris loading or a rogue log etc.?

    METRIC !

    Massey, I was rambling about grads (an angular measure) not gradient (a slope akin to the Tan of the angle). It seems all those years at school learning about pennyweights, bushels, rods, guineas & fathings, chains, gram, litres (liters, see I can at least spell another language) reams...

    METRIC !

    Owg - We have split up the circle into 360 degrees basically since the Sumerians adopted a base 60 and as surveyors we split up the degrees by further 60 subdivisions (minutes) and again (seconds). We repeat this in organizing time (seconds and minutes again). So there could be an argument for...

    METRIC !

    I always thought that the imperial system was a better system especially when using units to the base 12 (inches and pound[currency]). It was easy to divide things between people for barter for instance (1x12, 2x6, 3x4)... but now we have grown beyond that using mathematics as a tool for many...
