I am hoping to detail how a careful and patient person can make cases without the expensive tools. It can be done.

Hi nigel, I too had problems with making the cutouts that is until I tried the method of chain drilling and filing. Basically you mark the hole you want to cut out. then with a small diameter drill drill many holes close together, then using a needle file (or fine wire cutters) remove the material between the holes giving a bigger hole. Finally file out using appropriate small files until the hole is the size you need.

Attached are a few images. Not the best choice as what I thought I needed wasn't (ie I thought I needed a simple round hole) and the ending hole doesn't look like what it started out as, but it will give you the general idea

Tony.

Sorry, can't help you out. I have Solid Works and Qcad. Neither of those, are all that happy communicating with Autocad.

That's OK. I will work on it.

I would like to link to this thread also. Some good points are made here.

Much better. A drawing like that, requires no technical background to understand.

I usually make drafts like that when explaining beginners how to do something.


You need to get yourself a young apprentice, then you will be reminded of what's not obvious

If already mentionned, just pass...

The simplest way to make a case is to directly screw plates on the heatsinks.
No more parts are needed.

If already mentioned? There are only 16 post to read through so far. That hasn't been mentioned yet. I had to start somewhere, and I wanted to present as many options as possible. That can work if you already have two heat sinks and they are the length you need to provide the case depth you want. What if you wanted to put the heat sink on the back?

Thumbs up At least! Steve, bravo for your initiative!

This is an extremely useful thread, which was a serious lack in diyAudio forum. Some of you, you are members of M.O.A.N. society like me. The vast majority of threads in this forum is consumed in theoretical approximations and discussions, which in the best case end-ups in PCB implementations. I have a different option. There are hundreds of ready offered circuits. The only that we have to do, it is to select one of them as is or to make combinations-modifications of different of our liking, to enclose in a case. IMHO, the external appearance of a project it is equivalent with the circuit used inside. A nice-looking case it is a must for this.
Probably, you have seen some of my projects in "Post your solid state pics thread" in which i have posted as well pics of my tools. I spent around 1200 euro to buy ready tools, or to make some by myself. This time i am in the process of building one power amplifier and one preamplifier from the scratch, and i have started from the construction of cases which is the dirty work. From luck i looked in this thread started from Steve, and i thought that it is a good chance to contribute as i have the cases of projects in the process stage... you know: sketch on the paper, measuring of dimensions, cutting and drilling, some corrections etc.
I attach some pictures of the chassis of amplifier assembled off-hand for confirmation of precision of cutting, bending and drilling; i will attach separate pictures of each part during disassembling. I hope to will be consistent in my promise, because i must to deliver the two projects in my customer in one month to get some money for celebrating Christmas like all the Christians; and above all to fill the oil-tank of my central heating, because the strong cold starts in December at Greece, and my mother is 78 years old! I have spent already my customer's advance of 400 euro in my dentist. I ask your comprehension in the case of delayed replies because the above. You should know that this is the only job which i have for living. OTOH, i will take shots of each stage of construction to post later with explanations.

Fotios
