I need to relocate some Machine Tools, some of which have foundations (3-4ft Re-enforced Concrete).
One of our sister companies placed a Steel Plate and Epoxy beneath one of their Machine Tools in lieu of the manufacturers recommended foundation. They Claim that this has worked quite well. So...
I have a VTL which needs a new Thrust Bearing, but I don't have the luxury of waiting 10 weeks to 30 months for a new bearing to be manufactured.
I have ordered a new bearing but in the mean time, I would like to entertain alternatives that would allow me to functionally run my machine tool...
It isn't angular.
There are two Cylindrical Races 24" ID x 28" OD x .982 Thick. There is a Track ground into each Race with a .540" radius around a 26" circle. (The 26" circle may be slightly diferent.) The Tracks are about .200" Deep. Approximately 60 1.0000" Diameter balls ride in the tracks...
I have a thrust bearing sitting on my bench. To order a new one would take 30 plus weeks, which I can ill afford.
I have decided to approach a few machine shops to quote repair or replacement of the races. But before I do, I want to understand the difference between the Ball Diameters and the...

I am i need of a 16,000 to 20,000 Welding Positioner. Does anyone have a surplus positioner?
I appologize for asking this question in this forum, but I'm in a bind.

I would like to thank all of you for the informative conversation.
I think it is time to give a little background.
I am building Valve/Actuator packages and I would like to design into the actuator a closing profile which slows the closing time toward the 100% close position. I have a fellow...
Is Water Hammer the resultant "Noise" from the shock of acceleration of water? If so, Water Hammer is nothing more than vibration.
Is there a point when Water Hammer is pressent and not detectable by the human ear? If so, would there be any damaging affect because of the seemingly small amout...
Big Inch:
Thank you for your reply.
I'm thinking of more along the lines of a length of 50-200 ft. and an outlet pressure of close to the same as the inlet. The elevation would be nearly horizontal (not more that 10 feet)
Darrell
If I now the pressure and the Pipe size can I calculate the flow rate?
I have a piping system with 8 inch Schedule 40 Pipe, and I have a constant pressure of 175 psig can I determine what the flow rate is in gpm? The fluid is fresh water.
Respectfully,
Darrell
I have been approached by a survey team who suggest that I need to do a "...Sub-Slab Depressurization..." on my building. I have a 20,000 sq. ft. commercial structure with a 30ft high roof.
I have been surfing the web for some information regarding the need and cost of this procedure. I have...
I have an application that requires a close seal (5 scfm of air @ 200 psi @ 935 degrees F). A metal to metal seal is working alright, but it is very expensive to make economically. Is there a material that is slightly pliable and heat-resitant that could be used for a seat in my valve.
Thank...
I need to quiet my air compressor. I have read some literature on noise reducing/dampening materials. How do I know what product is right for my application?
Thanks in advance for any help.

Hi, Hopefully someone here has experienced what I'm experienceing.
I've upgraded from Cadkey 6 to AutoCad 2000, but I still have my old plotter (Hewlett Packard HP-GL/2 Languge DraftMaster SX Plus).
I've been trying for several days, and have yet to get a successful plot. I'm sure that it is...
