Contact the OEM of your unit and buy a supply of the properly sized o-rings depending on your useage requirements. It takes longer $$$ wise to make one than the o-ring costs (usually) O-rings are cheap why waste time on them?

"we built them in record time". You did a very good job of stacking the deck. The good quality is great though. I don't intend to be negative but a good time standard in a production environment is an average of many studies with a LARGE population of varied skill levels. There will be the...

Try this thread it has some good info thread284-73360

Check out www.practicalmachinist.com --- there are many folks there who would be happy to help.

engroshdy24, The type of information you are asking for is all over the internet and of course it is free. All you have to do is put out the research effort. See below for some examples. http://www.google.com/search?hl=en&q=speeds+and+feeds Of course it really isn't the same as owning your...

This was posted early in NOV by kenvlach --- in this forum -- http://www.eng-tips.com/viewthread.cfm?qid=201484&page=1 It was very interesting.

tygerdawg, All of the folks responding to your question are far more knowledgable than I in this area so my suggestion may be way off base. The machines I work with have the option of being setup for 3 phase low voltage wiring. Is this possibly an option for your machine? [bigsmile] You...

itsmoked, Glad to help. [smile]

itsmoked, This may be the thread you are referring to. thread237-95234 humbled, Hope the thread above is of some help. [pipe]

Oh, I forgot to mention that you might add a spring, pneumatic, or hydraulic tensioner wheel/pulley/or sprocket in addition to the existing take up. On some of our conveyors the actual take up is mechanical and the take up pulley is stationary. Tensioning is controlled by the tensioner...

Have you considered using a pneumatic take up, not sure if it will work in your environment though. We use the pneumatic take up on very long belt conveyors and it works quite well.

I Googled -- Define Lhmr -- I found that this has something to do with harmonic functions, not sure if this helps www.springerlink.com/index/g32628t02158t477.pdf Several of the other results may be of interest to you. The web site does not explain much but might get you in the ballpark...

If the material is bent on a break (or otherwise) there are processes for heat treatment to return the material to, or near to, its original condition. I am sorry, it's been a few years and I cannot remember the process specs for HT on various materials. Good Luck whichever way you do it...

Thank you both for the replies. I didn't think a sudden change in temp was a good thing.

I am not a professional welder as a trade but do maintenance on conveyor equipment. Occasionally I must weld broken parts or fabricate patches or replacement parts. The folks where I work who weld (ARC) more frequently than I, immediatedly run cold water over the weld until it is cooled. Is...

Very nice contribution --- I don't have room to download this but I am going to keep it in my favorites. It is interesting to see how things have changed and more-so to see how some things have not changed in all the passing years. Thanks

Here is an interesting website, hope it helps http://www.physics.uoguelph.ca/tutorials/vectors/vectors.html

See if this helps --- I Googled for countersink tolerance and got a bunch of choices. Here is one. http://www.guden.com/countersink.htm

Look in Grainger, Fastenal, McMaster Carr or other fastener supplier catalogs and see how they are sold. It is the best way to get what you want. In McMaster Carr there are very helpful explanations of "What Is A ???" for most of the products in the catalog. This is not an engineering answer but...
