Jul 10,2007 Twelve equally spaced holes are to be drilled in a 34 1 4#0183;If the diameter of the circle is 240 mm,then the adjacent and hypotenuse of your triangle is 120mm.With eight holes equally spaced around the circle,there is a 45 degree angle between each hole.sin(45) = opposite over hypotenuse.Therefore opposite (distance from hole to hole) equals hypotenuse * sin 45.Hope that helps.You have probably already given it more thought than the designer of drafter did when making the drawing.I would treat treat is as a basic dim andI agree. If the feature is otherwise located using basic dimensions,it is safe to infer that the angular dimensions are also basic. Believe it iIs equally spaced a valid callout within ASME 14.5? Thanks,AnthonyI don't recall 14.5 addressing this issue. Believe it if you need it or leave it if you dare. - Robert HunterI'd treat the equally spaced as basic.A possible way to figure it out,does the positional FCF show a diameter symbol for the tolerance zone? If1Everyone aboce is correct.Here in the USA it is OK to call out equally spaced,except use EQ SP.I have not seen anything that says you can't usThe FCF shows a .004 diameter tolerance zone. The old-timer's opinion is that you would divide 360 degrees by the instances (3 holes). That wouldActually,in ASME Y14.38-1999,Abbreviations Acronyms,the abbreviation for EQUALLY SPACED is EQLSP,if you care.

The annular space between casing and hole should probably not be less than 5 cm (2 inch).A long,slender rod can also be used to make sure the grout flows into all voids.The grout should extend from the surface to a depth of at least 6 m (20 feet) to ensure an adequate sanitary seal between casing and drilled hole.4.11 Problem solving3 Tips for Drilling Super-Straight HolesJun 01,2014 Twelve equally spaced holes are to be drilled in a 34 1 4#0183;If you're trying to drill perfectly perpendicular holes through a piece of wood and finding yourself continually frustrated,try one of these quick hacks.Advertisement - Continue Reading Below 1 1.
