Wood Casses.

I am wondering if it is worth it to use wood as a material for a comp case.  Metal is easy to work with if you have a properly equipped shop but that can be tens of thousands of dollars easily. Plastics can be molded, form a Polyurethane based foam but Wood is the easiest to work with.  Some issues I have thought of are Cooling, and that you don't want humidity to be way to low, or for heat to be real high.  Wood has a low conductivity, mainly because of moisture inside of it, but once sealed with polyurethane or something would be fairly resistant to heat, dryness, and even static electricity etc...

I think this has probably been done, but I am wondering how feasible it is.

Re: Wood Casses.

I don't see any reason why it wouldn't work. Radios and TV's used to have wood cases. I can tell you those old vacuum tube machines made a buttload of heat and had no fans. With proper ventilation a wood case should be OK. If you use reasonably heavy material it should block fan noise better than a sheet metal case.

If you don't mind going old school you might want to consider shellac for the finish if you are concerned about static.

Re: Wood Casses.

Well, it's been done before, so at least we know it's possible, eh?

Re: Wood Casses.

I did a lot of wood shop work back in Jr High (cause the HS didnt have shop). I'd say it be entirely possible and quite fun to do. To get the straightest cuts i'd recommend having either a band saw or a scroll saw. Course, table saw would probably work too but I was never proficient with it as much as with the band saw. Drill press would be nice. Then just need something to sand the edges down with.

As for wood, I always perfered hardwoods more when I worked with it but its up to you.

Re: Wood Casses.

There's only one REAL reason not to use wood in my opinion.  It can spew out RF in massive amounts if you haven't shielded the innards with metal.  (Of course if you hate your neighbors TV viewing habits, then that's not a bad thing at all...  smile  )

Would I be wrong in assuming that you're surrounded by a RDF? This seems farfetched.

Okay, so they're prefab. But they're wood! big_smile

Nope, no RDF, plain old RF.  Whenever I crack open my B&W my TV starts ghosting.  I have cable and the TV is downstairs from my computer, so this sucker has to put out quite a bit of RF for that to happen.

Re: Wood Casses.

Hmmmm, was wondering where that came from after I got my Cube lol.

Ya know this wood case idea got my mind thinkin. If I had the tools, it would be freaken sweet to do a wood expansion case for my Cube. Man I wish I had gotten those machines years ago so then I could design it properly.

I had a CP/M machine 10 years ago that put out a buttload of RFI. Even wrapped in 2 layers of aluminum foil it scrambled the cable signal so bad you couldn't see or hear anything intelligible on the TV. Even the landlords downstairs got some interference.

Re: Wood Casses.

You could line the inside with something to block the RF, or even have 2 layers of wood and something in-between.

Yeah a band-saw is the proper thing to use for really detailed stuff, Table saws are great for really long rip cuts(cutting into the grain) and if they are adjusted really good and have a good blade are fairly accurate.   Drill presses are necessary, a hand drill is ok but for real precise drilling they pretty much suck.

Chop-Saws/Compound Miter saws whatever you want to call them are great for precise miter/rip cuts.  A large bench Planner is also very important, you can take some really thick stock and get it down to 1/4 of an inch thick if you want, down to a 32 of an inch accuracy.  Jointers are also important to true the edges of the wood and are great for rabit joints, otherwise you would need to spend the day with a hand plane for the same results.

Jig Saws can be accurate with a really fine blade, but you need a hell of a steady hand though.  Circular saws are accurate for Framing Carpenters, and if you take a square to any angle in your house it probably won't be quit accurate, if anywhere close.

Routers are important and of course the whole slew of Power sanders etc...

Re: Wood Casses.

I'm drawing up plans for a 'Snow' PowerMac desktop using the innards of my Sawtooth 450. Wasn't sure what to make it out of.  Wood, with a heavy epoxy paintjob, sounds about right.

Just checked Lowes.com for MDF panels...their 1/4" thick stock goes for $23 but it's 49"x94" -- fweakin' huge. Guess you could make a bunch of cases with it, or have spares for goof-ups.

What kind of blade/cutting tool works best for MDF? I wouldn't want to feed it to my circular saw -- it'd eat it alive...

it would?

OMG eek

and here I've been using table saws, miter saws, circular saws to cut MDF.

damn.

better find another way.

fwiw, MDF is too heavy. use something nice, like a birch plywood.

I was talking about *my* handheld skillsaw. And you're right; birch ply would work much better. Finishes much smoother, too. A white, candy glossed finish would stick better to real wood...

I'm going to forgo cutting myself and find a buddy with all the tools wink
