Are you serious?
Fir or pine 2x8's will hold up a effing HOUSE... full of people, all their crap AND furniture. They can damn well hold up a few hundred lbs of old test gear. If you're REALLY worried, screw two of them together for your uprights. Quick, cheap, and strong. When you're done building, drown it all in urethane and write it off your bucket list. Get some perspective, man. Stop overthinking and start BUILDING.

"Fire good, tree bad"... that's the level I'm operating on right now.
Wellllll..... i could do that, or close, but i'm right back to the damned things straightness. Though if i made 2 3x3s then made and added a 1x3 to each face i guess it could look alright maybe...
nope still like the idea of hickory!
Also, i AM building, the posts are the last and currently i'm still one step one get the boards for the frame cut out and flat.
FLAT! Dammit! FLAT!!!!
And now we recurse right back to the "This is a BENCH. To WORK on. it is NOT fine cabinetry." part of the discussion. Tolerances of 1/4 INCH, not 1/4 mil are the norm here. Again, perspective, man. Lapping two planks together is a perfectly valid building technique, and it is how you MAKE straight lumber out of #2 pine. Once you build the shelves and cover them with gear, the wood they're hanging from will be the last thing you notice. It makes no difference if your posts wiggle 1/4" or even 1/2 an inch from one end to the other; what matters is how carefully you place the cleats for the shelves. This isn't rocket surgery; you're building a rock to lay the rocket ON while you operate.
If the posts are the LAST thing in your build, then you're building it WRONG. You'll never get it square & level if the posts are an afterthought. Instead of hating the look of the lumber, incorporate the look into your design. Post & beam is a classic architectural design; follow those principles and even if you are using the simplest building materials, it will come out looking stout and "heritage".

I am suddenly very, very tired.
Hmm, if you have a 3" x 3" leg and then you cover each face with a 1" x 3" then you will not end up with a square leg, to do so you would require 1" x 4" 4 off or you'll need 2 off 1" x 3" and 2 off 1" x 5", so why not just with 5" x 5" legs and no face covering?
OK, OK. I'll wait, next time.
LOL - no worries. Actually, in that test mode, it's SUPPOSED to read 100MHz, so that part is working correctly. Perhaps it will come in from 99.9999 once it has cooked for a while - lord only knows when it had last been turned on.
Ah, OK. It sounded like it was way off. If it's supposed to be 100, then 99.9999 is close enough.
Just wanted to pass on a smaller fleaBay find... this is apparently a fellow tinkerer who has hooked up with some local equipment scrappers to make some TEA money.
...
His store motto is "From my basement to yours: If you don't need it, I HAVE IT!!!" I wanna support him just for THAT!
Ah, yes. I've bought from him before. Can't forget that saying, since it's so TEA-like.
I bought 2 of the 100ohm 0.1% resistors and one 25-ct strip of the 5315ohm 0.1% resistors. I intend to put them all on a breadboard and make a ladder strip with double rows of 0.100" pins & jumpers so by putting in series or parallel I can make a very good, very cheap scalar resistance array that should have values pretty much in the middle of every range up to 500000 ohms.
Awaiting pics...

In other news...going to have to temper the TEA spending for a while. The Honduh CR-V took a flat tire. And it's not repairable. The tires are just about down to the wear marks anyway but I had hoped to get a few more months out of them before replacing. But that suddenly became now. So the wallet just took a big hit. Tires are on order and should be delivered Tuesday. The UPS guy is gonna hate me because he'll be jackassing 4 tires.
For the guys in the USA.....Tire Rack is my go to source. Decent prices and free shipping. And no bullshit add on taxes and fees. The quoted price per tire is what you pay. But going this method is a little inconvenient because now I have to take them to a shop and pay to have them installed.
And it's cool!
Oh. No. Must. Resist.
Oh. No. Must. Resist. Buy.
My work here is done.

Yeah thanks for reminding me, I'm going to be in that boat with you for the next month or two, over the next 2 weeks my car has to have its annual MOT test, brake fluid change, tax and also insurance renewed

Err... complex design feature that i will try to explain.

OK so the complex design bit
4 legs held in place by a frame(white), then there is a cradle(purple) attached to the back of it for the posts and further strengthening of the frame, next comes the slats(gray) which are non-structural ie entirely for a small shelf, next the
top which is a layer of 1/2 in mdf 1 in white fir and 1.5 in pine, now come the
posts, with the top in place i can set them on the cradle and if that end is at least reasonably straight then getting it square will only be a matter of making sure it is sitting correctly and then double checking it to the top with a speed square. In the picture i used a 3x5 for pine and a 2x5 for hickory. In the case of pine i could add one more 1x3 onto the back that would screw directly onto the cradle and posts. Make any sense? Also i already have the cradle ready to go pretty much, bit late to change the plans.
As for why it has to be dead straight to the top? Probably just cause i'm obsessive compulsive.

They can ship to a shop so you don't have to schlepp them. Not sure what limitations may be on that, though.

I just looked at their prices, and whoa... you REALLY need to look into Discount Tire. Everything they say is "Free"... you're DEFINITELY paying for it. And THEN paying someone else to install them, and THEN the headache of self-administration of your certs. Yeeeowwwch.

Regular Show... *brrrrowwwwwrrrrrowwwwwrrrrrrnnnn*
So... what you're saying is you've got plenty of time to save up for when the price inevitably drops. Win-win. Y'all get something to look forward to, and this unique bit of TE becomes a TEA.

Also, it can count 3-eyed fish.
Yes pine work surfaces are not all that resilient to rough handling. Just tilt a boatanchor onto a corner on a pine surface and it will have a ding in it. It can be better if you put a tough coating over it to keep away scratches but dings are still going to happen.
I did screw a bit with my DIY bench. I finished it the work surface of mine with parquet lacquer. The stuff is really tough to scratch and it makes for a quite pretty looking smooth surface that's easy to clean. But then i found out that PCB cleaner (IPA+Ethanol) or pure ethanol just melts the lacquer right off.
I guess kitchen counter tops still have a point there in toughness but that would make my bench look like its from Ikea. It may not be the oval office desk but its still my lab bench and a nice hardwood top just makes it so much nicer. Sure a Rigol DMM or a Agilent DMM both measure stuff but witch would you rather have?
