Cables?
One update on the last post… If anyone needs some decent-quality RCA interconnects, I’ll make them and charge only parts. Other people going in on cable will let me afford the slightly larger spool. (500′ is only 3x the cost of 100′) Let me know ASAP.
:)
Well, it seems that the audio interconnects that I made need to be replaced. Turns out I was using standard, good-for-RF RG6. This has a copper-plated steel core with a 60% aluminum shield. Not bad, but it explains the extremely hard time I was having with soldering to the braid. Whoops.
Anyway, I think tomorrow I’m going to get a hold of Graybar and see if I can get 100′ of Belden 9259. It’s an all-copper coax, with a stranded core. Should be quite a bit easier to work with… I’ll just have to get some more connectors and resolder things. Shouldn’t be a big deal. :) The subwoofer does function right now, but I’m concerned about using a cold solder to hold the ground together. It just doesn’t seem like the best idea, to me.
So, hopefully this will work out for the best. I’m wondering if I should get more than 50′, in case I want to make more custom interconnects in the future… I’m just not really sure right now. I’m thinking that it might be nice to make a run from my test 2003 machine to my home theater stuff, that way I could listen to streaming audio in the basement…
Hmm…
Would anyone be interested in some coax for making custom, high quality audio interconnects / subwoofer cables / whatever? For about $0.30/ft + connectors and with a soldering iron you can make your own high-quality interconnects!

For anyone who’s interested, I’ve posted a new recipe: Pumpkin Cheese Coffee Cake.

Yes, cutting tenons into long oak pieces on a table saw without a dado blade isn’t the best idea. My hands are sore and cramped just from holding the pieces against the miter. But, the results are looking good… I’m going to try to work on these a bit more tomorrow before class, and then I should be set to do some sanding before the major assembly of the head- and footboards go.
Oh, in case you don’t know, I’ve been working on building a solid oak queen-sized bed for about two years now. I was constantly putting the project away in order to work on moving into my condo, the rooms upstairs, or various other things. Well, I finally have a table saw, and with that, most of the tools I needed to keep working. I just need to keep the motivation going… There’s still the finishing of the mortises, cutting of the large curve in the head and foot boards, sanding, assembling the head and foot boards, adding the spindles, finishing the side rails, then staining and applying urethane to everything.
Oh, here’s a picture of the bed I’m making: http://www.dingleberrypie.com/gallery/bed/aac

RIVETHEAD!
Wow, I feel like a true out and out rivethead tonight. I just spent the last hour filing, grinding, and wire brushing a 10″ x 20″ piece of 6061 aluminum alloy. See, when the G5 comes, it’s not going to fit on my shelf. Because of this I wanted to make a shelf for the G5, so it’ll sit nicely and look all pretty and stuff. My first choice was a nice 1/2″ thick piece of glass, but that ended up being too pricey; almost $70. Next, I consulted lowcostmetals.com after hearing about them from a friend. Turns out that I was able to get a appropriate sized piece of aluminum for $32, shipped. Not bad at all…
Anyway, the aluminum slab is a little scratched and was rather worn, so I decided to give it the most appropriate finish I could think of: brushed metal. Well, tonight I filed all the edges to nice 45°, put the wire wheel in my drill, and gave all the surfaces a fairly decent brush job, removing all but a couple of scratches. I think it looks pretty good…
As I was in the middle of finishing off the slab of aluminum, I remembered something I read online when reading the 6061 Aluminum Material Property Data Sheet. It seems that if one wishes to artificially age 6061 aluminum, it requires “350°F for 8 hours followed by air cooling” to reach T6 temper. Poking around Google, I found that T6 is a pretty hard temper, and I figured that it would be good to temper this stand, just to hopefully cut down on any more scratches.
So, in the oven it went. Seeing as this is a decent sized slab of metal, I’m going to give it 10 hours in a pre-heated oven. That means come 10:00am, I’m going to wake up, turn off the oven, and let the slab cool. Woo! Before placing the slab on the rack in the oven I made sure to wipe it down with isopropyl alcohol while wearing latex gloves. Hopefully that’ll eliminate any heat-assisted oxidation that may occur. If it does, I’ll just steel wool it off.
After the oven treatment I’m going to throw a number of coats of satin urethane (yes, the same stuff I used in my furniture) on the slab and call it done. Hopefully it’ll look nice… My tests with this urethane on various computer parts and metal pieces seemed to give a nice overall dulling, yet smoothing, effect, which is just what I’m looking for… So, we’ll see what happens. :)
Oh, maybe some pictures…

Well, just one, but that’s all right. I also put together the new table saw tonight, but I didn’t cut anything, so that part wasn’t as industrial as it could be… Woo! Italics…
Anyway, I think I’m done for tonight. I also slapped together some extra-low-cost shelves from Target to give me a place to put my vinyl and books in my office. Those worked out really well… Pics will be forthcoming, most likely after I get the office all put together. Finishing that will entail about two hours on my back, tying cables up above my head… Sort of the way I hurt my chest before. Sort of.

Yay! I stopped at Sears Hardware on the way home and I *finally* have a Vernier caliper. With me being as anal as I am about things being accurate, I can’t believe that I never had one. Now I can finally measure things accurately. No more silly tape measure trying to determine if something is 7/16″ or 3/4″. Heh.
…
Well, it seems that if you take 6061 Aluminum and heat it to 350°F for 8 hours, then air cool it, it will be hardened to T6 specifications. Once I get the stand shaped as I want, I think I’m going to try to temper it in my oven. I can’t see any reason why it’ll cause any problems, and the chemistry of 6061 doesn’t seem like it contains anything that would be harmful to have heated up in my house.

Ahh… New Klipsch ProMedia 2.1 speakers came today. I’ve now replaced my older Altec Lansings from 1995. The ALs were really, really nice, better than most other speakers, but they had a bad 60Hz buzz coming from the subwoofer. I got these speakers as refurbs for $99 for the pair, with sub. They retail for $179 – $199. Not a bad deal… I’ve only had two problems. First, they forgot to ship the speaker cables with them. A phone call later and they are on their way. I’d been wanting to make some custom 16 gauge cables for them anyway, so I got out two 3.5mm mono plugs (yes, the back of the speaker accepts 3.5mm plugs for the amped signal, for some unknown reason…) and the speaker wire, then made up the connectors. I thought about putting six-way binding posts on the back of each speaker, but I can probably leave this work for another day. If it’s even worth it… Anyway, I hook everything up and they sounded like shite. After some troubleshooting it looks like there might be a problem with the input line, some wiggling around in the iMic (USB sound device for the G4 Cube) and everything is good. These speakers sound real, real nice. Definitely worth $99 for the pair. Now I only need to rearrange the office… And find a new place to mount the iSight, as it had sat on top of the old speaker.

Ahh… Tonight I went to my first day of college. Ever. Tonight’s class was HIST-2000 (formerly HIST-200) which is all about the history of invention and technology in America. Tonight’s class wasn’t anything special, just a hand-out of the class syllabus, a schedule, things like that. The class seems interesting, and judging by the students, shouldn’t be too hard to pass. There were a bunch of fresh high school grads, a couple older people, and me. It seemed like there are a few other twenty-something students, but they didn’t really stand out.
After I got back home I decided to start in on staining wood again. I applied the second coat of stain to all the table tops and bottoms and one set of the legs. That leaves only eight more table leg sets to receive their second coat of stain. After that comes the top coat… This will be the hard part. I think I have a plan, but we’ll have to see how it works out. It’ll likely involve eight or ten separate sessions of urethane application. That’s a lot. At least it’ll be worth it in the end. Tonight I took a test piece of oak that I had stained and then applied four or five coats of urethane to. I let my intentionally very wet glass set on the surface. No ring. Then I dropped the corner of the glass from a height of about five inches. Slight dent, but no cracking. Obviously the parawood would dent a bit more, but what I was looking for was a lack of cracking. The only test left is a very hot bowl or mug of tea. If this passes the test, I might forgo the glass surfaces. If not, all horizontal surfaces will have custom cut pieces of glass fitted to them. It ought to be nice to finally be able to sit in my living room, listen to music, and have tables to set things on.
