Default Amp Cage Fababricators?

The first amp I restored was a Dynaco ST-70 with cage. I worked on it upside down while supported by it's attached cage which rested on a heavy sheet of cardboard, enabling me to spin the entire assembly around on my workbench without scratching the cage.
Right now I'm working on a Pilot 232 Stereo Plus, but it lacks a cage. I would like to have a cage fabricated for this amp and another (Fisher 481-A. Although I may not run either amp with a cage, I would like them just the same, for service and storage.
Any suggestions and experience with private fabricators?

I don't have a problem brazing, soldering or spot welding, but I need a brake and shear to do a classy job.
Hell, I could do it with an Erector Set if I had to.

For use it would have to be a cage, but for service and storage it could be a simple MDF or plywood box. For servicing only, a simple jig from MDF or ply works well.

I normally service my amps propped on books in a shallow cardboard box. However, I like the idea of having a "built in" service cradle to go with an amp. Supporting the amp upside down by a ventilated cage is a little safer and more stable when measuring voltages than on books or in a closed box. I know this because I have an unventilated box but it gets pretty warm in there.
This is nothing critical-I was only wondering if anyone had the name of a fabricator and was satisfied.
