Title: into perspective
Post by: Melvang on Thu, 03 April 2014, 14:58:36
For those of you that wonder why I would want to build a keyboard case out of half inch plate, I just want to put it into perspective with what I do at work. 

Today I had to do a shaft alignment between theotor and the pump on an air compressor.  The alignment was damn near perfect when I finished.  Offset missalignmet was within .0002" vertically and .0005" horizontally.  The angular miss alignment was within .0017" vertically and .0000" horizontally.  Here is a picture of the placard from the side of the motor.

I would love to have a metal case as long as I could carry it without getting a hernia. My naked stealth F has a handle that is good.

Raw metal would look supremely bad-ass to boot.

By "plate" do you mean steel? Obviously titanium would be the best all-around, and copper would be scary wicked steampunk, but aluminum would be plenty adequate for the proletariat.

Realistically, at about 8.25 pounds, my F-122 is about as heavy as a keyboard needs to be. Somewhere around triple that weight and it would start getting obnoxious and unnecessarily cumbersome.

Fixed that for you :P

Should be a steel plate. And I agree, I always liked the look of raw metal.

wow

that motor is 4 metric tons. Then I checked the power requirements: 2300V at over 300A! That's intense!

Tungsten carbide cases and plates FTW.

Just think I have set motors that were only 1,000 hp that were lower RPM but drew more power and weight much more.  But those were built back in the '40s and '50s.
