a good chassis can be another costly component of an amp build. luckily, sometimes we don't need or want a good chassis! if you are in this situation, the easy solution is to build your amp inside a cakepan.
advantages:
cakepans are cheap ( ~ $3 - $8 new.) they are also easy to machine.
sometimes you can get them for free. they are a good temporary solution for experimental builds that may not last long. they're almost disposable!
disadvantages:
easily bent by catching drill bits. poor dampening of vibrations. difficult to mount in a cabinet. get hotter than standard chassis. non-stick coating needs to be sanded off of grounding points
here are a few pictures of my "cakepan amps"
