[AMRadio] Steel chassis

[Bill Guyger]

You are right sir!
 
But, if you're building something heavy like a Power Supply you can do what I have done on a couple of projects and sandwich a 1/8" Aluminum plate to the top of the chassis and add Aluminum cheek plates from the sides of the chassis back to the front panel. It creaed a pretty rigid box structure. Aircraft designers do it all the time and it works great. You do have to punch / drill through the two layers of the top plate and the chassis, but it isn't much more difficult than working with steel which is much harder.
 
I can send you a picture of a dual Power Supply I built for a 813 based transmitter if you'd like. I'd just attach it to tis e-mail but the list doesn't allow attachments.
