Water Jet Cutting very cool

Wire burning does have its limitations.

Yep, it is relatively slow.

My Southern Indiana Dialect is hard for some to understand.

That's why I read it slow.

I type slow when I know Indiana guys are reading it..

[canuguzzi]

Yeah , but newer than bakelite phones

Have you seen the prices of old Bakelite bowls and other dinnerware? Crazy, who would have known?

Good Bakelite is practically indestructible, light and can be made into almost anything.

A Woman just called me from Georgia regarding work.  She sure helped me with my insecurity when it comes to speaking with my Southern Indiana Twang.  Amazing the dialects we have in this English speaking country.  Tom, I have to re read my post slow also.

Yep. When we picked up the Aero engine, the owner spoke southern Alabamian. I confused Union creek Baptist church with Indian creek Baptist church, and almost never found the place. We used sign language when I finally met up with him..

A side story, when we were building the frames for the cutting head to move on the x,y,z axis, the weldment's would stress and twist. 
I sent the frames to a company that would stress relieve them by placing them in a large oven.  The frames would go out of our shop with on leg 1 inch off the floor and come back with another leg off the floor and the original on the floor.  Then when we would put the frame in the very large machining center, the cutting tools would relieve more stress causing more twisting.  This was huge problem.  I made some phone calls and a guy showed up with a his "special tool".  I was reluctant to believe his stress relieving tool would work. 
Off to the shop floor we went.  The tool consisted of an angle plate made of 1" plate with 12" square sides.  On one of the sides a D.C. drive variable speed motor was mounted.  In the black box of tricks was several steel disc with a mounting hold located at different distances off center.  The motor was connected to a control panel that would control the r.p.m.'s.  He mounted a random plate to the motor and two knock sensors several feet apart on the frame.  The control panel had a tachometer and two needle gauges connected to the knock sensors. He C-clamped the angle plate to the frame and started the motor.  The frame started vibrating at the frequency/rpm he set it at.  The two knock sensors had different readings on them.  He let the motor run until the two knock sensor had the same reading.  This would take several hours and lots of noise.  When the same reading was reached, he moved the angle plate to a new location and started the procedure over again.  After several cycle, the same reading was achieved no matter where the angel plate was mounted or the knock sensors were mounted.  The frames would twist  and change shape thru out the stress relieving process.  Doing the same thing as the heat process, causing one foot to raise and another to lower.  We still had problems with the machining process, but it was never as bad as the welding.

The vibration from the angle plate was very aggressive.  We had to place large dense rubber pads under the frames (weighting over 6,000 lbs) to keep them from destroying the concrete and walking across the shop floor.  The salesman said not to stand on or sit on the frames because it would cause bodily harm.

Aha - the good ole "vibro stress relieving process" I was never sure if that actually worked !
