Having made the glib comment about making a chassis from a microwave cover I put my money where my mouth was and did just that for my Syncrodyne tuner project.
This is of course not a display chassis or a replica just a handy test bed to carry the parts.
Actually the chassis would be fine when placed in a cabinet that hides all the hammer marks on the metal!
I'll do a PDF of the article and send that to Brad for attaching to this.
Cheers, Fred.

The other idea I've seen is an inverted metal baking dish!

So Ian if we use a baking dish, does that mean we can "home brew" or even "cook up" circuits?
Maybe even put some projects on the "back burner"?
Or even be "cooking with gas" when something works...……….
OK I'll stop now.
Fred.

Yeah Fred! Keep it up!

Seriously, for those of us with no workshop as such (just a kitchen table) and only basic hand tools (a set of pull-through punches is good to have), something like this

https://www.kitchenwarehouse.com.au/MasterPro-Non-Stick-Large-Deep-Roasting-Pan-38x26x7-5cm?sc=345&category=11225388

would be ideal.

The trick is to find it on the side of the road or at Vinnies and preferably not teflon coated.

Of course you'd never show it to anyone, it's just for testing valve circuits, which for me means checking that what I design on a simulator actually works the same way in real life.....

Now, to see if I really can get a reasonably clean 30 watts out of a pair of 6BQ5s when I drive the grids with cathode followers.....
