    How to safely contain a fall of heavy equipment?

    Hi all, I have a hoist that will be lifting roughly 5000lbs. My "weight" is in a skeleton frame (approx. 4' x 4' x 4')and will be lifted by cables. I need to implement something under it in case of a failure to catch it. I'm not sure what terminology to search for. I'm thinking air bags or some...

    Pillow block mounted on linear bearing???

    Anyone have any experience in this? My design is a lift using a lever so when the lever is rotated providing the lift the radius changes. I thought a pillow block mounted directly to a linear rail would do the job. Any thoughts? Thanks,

    Minature Slew Ring/Turntable Bearing???

    I'm looking for a minature internal tooth slew ring. I say minature because everything I've found so far is HUGE. What I'm looking for should be roughly 6" OD x 4.5" ID and very thin (not more than 1/2"). I did find one at Kaydon but it turns out that although it's in their catalog, they've...

    Involute Spline - ASA Standards?

    I have an old document that is incredibly hard to read but it appears there's a reference to ASA-BS:15. I think it should be ASA B5.15-1960 or 1950 but either way, I can't seem to find it. Does anyone recognize this and can help me get in the right direction? It might even be obsolete and cross...

    Hey all, I've got an electric motor in house that I need to test for a period of a couple days and am looking for a way to load it down.

    Surface Textures and Finishes?

    Hi all, I'm hoping someone can help me shed some light on this. Occasionally (like all of us) I have a machined part that is mating with another machined part. I've always seen symbols depicting a "finish" but I'm having a hard time understanding what values are used in/on what applications. For...

    Hi all, lets say I have a tube of material (any) and I cap both ends. Now I drill a hole in one side (end or whatever) and draw a vacuum. How do I determine the strength of the material being used on either end and the "tube". For the sake of the question let say the cylinder was 6061 alum and...

    Spiral Assembly Pattern?

    I have a round plate with a hole offset from the center that I'd like to (let me try to explain this) stack and rotate at the same time. Sort of like when you take a stack of napkins and twist the pile so it looks nice lol.. Anyhow, I think I'm on the right path but I can't seem to get it right...
