Hello, I have a low hours Mitsubishi Movemaster super RV-EN5J robot that we used to use in a robot cell for welding some time ago. It's a 6 axis 12lb capacity robot. I know we paid around 43k for it sometime around 2000. I am considering selling it on E-bay, but I have no idea what it is worth...

Thanks for all the help, that TD coating is very interesting also.

Jim, Could you recommend any good coaters in the GR or Detroit area? Also, if you could offer your opinion on what coating would be the most cost effective? I'd like the shear dies we use to cut stainless steel tubing coated for wear and gall resistance. I use hardened A-2 and D-2 pretty...

I am not at all against sending stuff out, It would just be so nice to have one in house. I know the components are not cheap, but I'd still like to try if I could figure out how to do it. Sometimes, I can get good equipment on Ebay for pennies on the dollar.

Thanks so much for the info, I am in the Grand Rapids area. I could live with a short turn around but I have sooooo many things I'd love to be able to coat. I'd actually like to build my own unit. I am a machine builder if I had some good plans I'd like to look into that. I was thinking possibly...

I am a toolmaker for my family owned business. I have an opportunity to purchase a nice heated CVD vacuum chamber for a low price. I know very little about the process or how it actually works, but I would like to. We perform a lot of tube cutting via the supported shear process. Our tooling...

That is a good tip, I'll have to check that out.

Got it, I was intending to look and verify I could not see light, meaning it would be IR. I have other identical machines that are working. I know the led is not working because it got ripped out of the board and is no longer there, (see pic). It is a 1984 brother CNC drill and tap model...

I am not sure of that but I can find out. I have other machines like this, I will check if they are IR. The encoder portion is not visible during normal operation but I may be able to turn the lights out, remove a guard and take a look.

It shines through slots in a encoder disk to what I think are photo diodes on the other side. Can I assume clear or white would work, I am not sure what the difference would be. I do see resistors on the PCB so guess I will try to use a voltmeter to determine the voltage needed. The zero side...

Pictured below is a PCB from a tool changer in one of our older cnc machines. One of the LED's has been damaged and I would like to replace it. Parts are hard to find for this older unit and if I can ID this LED it should be an easy fix. It's a 3mm dia LED, the circuit board has IH T-D94V-0...

I am looking for a simple inexpensive countdown relay timer. This is for a price sensitive higher volume OEM application so a low price is essential. It will not be loaded over 3 amps @ 120VAC. Preferred time range would be 12-120hrs but this is somewhat flexible. It will be simply switching...

Tell him what he wins Bob..... It's a new car! You may or may have not guessed it. [ponder]

I'm not limited to 1k but I do think an important element of any good design is achieving a good balance between price and performance. I'll report back if I figure anything out. That microphone triangulation theory has merit, but I wonder the performance implications of the object being...

Thanks for all of the input, and for some very interesting suggestions for me to consider and I appreciate it greatly. It is hard for me to get into much detail on this as I have signed a letter of disclosure and I am already dancing on the edge of the agreement. I appreciate all of the...
