Obtaining Chassis and cabinets
Hello.
Wondered where you can obtain blank chassis and cabinets from or where you can get them made. For example the one I am looking for at the moment is 7x10x2in, although the original design (H.F. Bands-Superhet) with 4 valves might increase to 7 valves with the addition of a BFO, crystal calibrator and voltage regulator this size might increase! The front panel is 7x10in. Thanks. Paul |

Hi Paul, Might be worth trying this outfit:-

Re: Obtaining Chassis and cabinets
In the past I have used aluminium sheet and bent it to shape in a metal press (very useful having a paint/body repair shop at work) or the other trick I have used is turning an aluminium pre manufactured box from Maplins upside down, mounting the valve bases etc on the "bottom" and using the "top" as a bottom cover. The range of sizes that they do is a bit limited though. They used to make a dedicated aluminium chassis in two sizes but this may have been discontinued now.

Unless, of course, you fancy something a little more whacky

Re: Obtaining Chassis and cabinets
Something worth keeping in mind is that for above-MW frequencies you probably want a really, really strong chassis for the main frequency determining parts of the circuits, like VFOs and other oscillators in particular. That includes anything, which carries mechanical forces to the main tuning cap, like tuning dials and more. So for good performance you should plan to use and make room for sub assemblies housed in, say, diecast Aluminium cases.
Most of the off-the-shelf Aluminium chassis' available are way too flimsy for stable HF operation. No problem for the Hi-Fi enthusiast, of course, but you will probably need more. Rule of thumb: If you can bend or flex anything using only your bare hands and arms (yes, simultaneously), then it probably isn't strong enough. Frank N. |
