    Casting different metals - same pattern

    I am anticipating a situation that may arise. I am designing a component that is to be sand cast in, say, Aluminium alloy but there may, in the future, be a requirement for the same component in Cast Iron(for the sake of argument lets ignore the actual grades of material). If we ignore the...

This stud has a straight portion, is then bent at an angle of approximately 30 degrees for a distance and is then bent back parallel to the original length. The two bends are...

    Can some someone please tell me how to create nested family tables. For example, if one has a family table of screw head sizes (for different thread diameters)and a second table for the various thread diameters and each of their available lengths, how does one nest the second table inside the...

    Rounds - single edge

    Hi I'm trying to create a round along a single edge but Wildfire 2 always wants to include a number of adjacent edges (chains)?. How do I prevent this as I need to give these adjacent edges different radii?

    Screw or bolt?

    The thread404-132824 re. tapping screws set me thinking about screws and bolts. When is something a screw and when is it a bolt? Machinery's Handbook (20th ed) defines a screw (amongst other edfinitions) as 'an externally threaded fastener......mating with an internal thread.... being...

    I have a shaft running in two ball bearings. The shaft is vertical and has an eccentric at one end and driving pulley at the other. The eccentric moves a mass of 132 grams which is biased against a bidirectional spring of stiffness 17 N/mm. (yes its all quite small). The mass is constrained to...
