    design of a drill spnidle

    Thanks for the suggestion, do you think a deep groove ball bearing would suffice, such as a 6205? Also I need zero slop in the system axially, that's why I thought a nut would work well, so I can give zero clearance on the cup/cone bearing

    design of a drill spnidle

    this is what I was planning on making for the spindle. Hopefully this bearing arrangement works shaft size is 1-1/16" for scalehttp://files.engineering.com/getfile.aspx?folder=7ebcec7a-ac05-42a4-9a53-69936eaf0146&file=spindle_Model_(1).pdf

    design of a drill spnidle

    I need to create a somewhat small spindle that will hold a chamfer tool on one end needed to chamfer hundreds of holes inside of a ring approximately 20" in dia. This spindle will be mounted to a plate and driven via belt. Once mounted I will have control of the z-axis movement (spindle...

    shop drawing connection details

    Its hard to learn here as i am the only one. Somedays it has its advantages, but it makes it hard to pick up on anything new. I am also pretty remote for any courses. I'll look around some more and maybe try to find a book. Thanks

    shop drawing connection details

    Yes, it can be easily over-engineered, but like you said this thing is so small there won't be much wasted time. The shop drawings are more of a formality than anything. Its just I've never done them properly (for a client), although i do construction drawings regularly. I normally add enough...

    shop drawing connection details

    Normally i do not create shop drawings, but we are working on some small platforms made from c5 x6.4 channel, which will require them. There is coped and butt joints, involved which are all welded. Does someone have an example on the proper procedure for calling out and detailing connections...

    ordox material

    I'm currently looking at a job that requires ordox bushings. I have never heard of or can find any info on this material. I'm not sure if its a trade name or if the spelling is even correct. They line a bore in a cast wheel which is loaded with 38,000 lbs. The axle pin is 410 stainless. Anyone...

    metal property sources

    Thanks It seems odd that to find extensive info on various materials is so difficult. I would think that major steel suppliers would have all this info readily available for customers so they can select correct materials for various jobs. It would make it easier for the engineer as well, to...

    metal property sources

    Im looking for a website that shows materials and the properties they have? I'm looking the web for different ASTM#'s and come up with all kinds of stuff. I tried metweb but i can't seem to find A513-5 on it or even A106b. I come across this lots and waste a lot of time trying to find info about...

    chrome-moly

    well i need a profile so 1" plate. This is an engineered stamped drawing and all thats stated is chrome-moly plate. I don't normally deal with the stuff except in shafting so i don't have much knowledge on plate grades. My guess would be 4130?? but theres also SA 387 Gr. 5,11,22 i see available...
