Whats your Work-Bench/lab look like? Post some pictures of your Lab.

What was the large transmitter (exciter) used for. It looks the same at the type used by the BBC World Service.

Last picture in the sequence.
Please educate me on what the equipment is.
Thanks.

GK has some really really neat stuff, I used to follow his posts closely....then he accused me of stalking him. 
Admire from a safe distance.

...and at the bottom a spectrum analyser.

Looks like the one I've got, only mine is yellow. Switching it on is a daring task, hoping the phase is not full at that moment.
Only transportable by one person if you take the units out

Please tell me more about this sexy piece of equipment on the left... I'm guessing it's a really high power RF amp. What band?

[wblock]

Please tell me more about this sexy piece of equipment on the left..

Obviously a teleportation booth.  But an older one, the new ones have quantum tachyon louvers, one or even two programmable locking oscillators, padded seats, and cup holders.

And they are monitored by an Arduino.

Little baby 10kW AM transmitter, and another lower power one,  Then a MANPACK radio tranciever ex military, and at the bottom a spectrum analyser.

Not quite. AWA model CTM2K - Does AM 2kW carrier. Is big because it was 1) designed for continuous MCW operation 2) is not plate modulated; it is a low-level modulated linear amplifier. It's original home was here: http://coastradio.info/adelaide.html To be resurrected on the 630m HAM band.
The AT21 (AMT150) was designed to be transportable but it requires 110V/240V mains and it is not a manpack. The power supply unit weight alone is specified at 170 lb. The one in the middle is a twin (independent) channel CW/AM/SSB HF band linear amplifier/transmitter that originally lived at Adelaide airport. Does about 1.5kW PEP max on SSB.

What is the custom gear in your racks, on the 1st/2nd pics.

Needed a computer table for the eastern corner of the shack. Desired something basic and sturdy as it might occasionally get a heavy piece of equipment plonked on top. Trawled through the on-line stores of various local furniture retailers but couldn't really find anything suitable. So I bought some 30mm RHS, two melamine shelving planks and an aerosol can of flat black spray paint and made one. Out of pocket about $110.

Not trying to be a jerk..but that bench looks kinds sketchy. 

[GK]

Not trying to be a jerk.

It probably just comes naturally.

.but that bench looks kinds sketchy.

The bench itself is made of two horizontal beams of industrial pallet racking uprights with multiple cross-bracing along the entire length. I step up onto the bench routinely and it is as solid as the concrete floor.

It looks good

Thanks

If it was for a heavy-use workbench then the lack of bracing between legs or the legs supporting the top only by the welds might be problems. As a computer desk/bench it looks great, nice job.

[GK]

The frame is sturdier than it looks. The legs are actually square but the camera makes them look splayed in the photo of the painted frame due to perspective distortion:

You certainly can't buy anything new that well built for $110 IME.  And nicely done to boot.

I happened to find myself at Ikea recently and saw some small $8 tables....ehhhh why not? 

Very happy with them, I couldn't bring myself to drop a couple of hundred dollarydoos for proper shelving or open frame racks.
Sorry for the slightly wonky photo, I was trying to contain my laughter from seeing cheap Ikea furniture surrounded by probably around an original RRP of >$50k worth of gear. What a great time as a hobbyist to get into electronics, so many bargains out there if you're patient (and luckily I am because I'm cheap).

[lukier]

These IKEA tables are famous for being 19" rack compatible

I would guess that it is sturdier than 95% of commercial offerings for computer desks. Most of the IKEA stuff is short screws into particleboard. What kind of welder/welding did you use? I have no experience but would like to learn.

Cool, good to see someone else in here welding.
Nice job. But personally I'd have put some small braces at least on the rear legs. Welds just at the corners like that have to deal with very great leverage, and if they fail they'll not give any warning.

Also did you know that the place which sells that steel, very likely also has plastic plugs for the open ends. They hammer in. Depends on whether you care what it looks like. They also help stop the steel insides from rusting.

Heh. I see you bought one of those red G-clamps with the screw foot made of sliced cheese. Which bent then fell off after the first time you used it?
Me too. Actually they are quite useful when you want to clamp with a point rather than a flat foot.

[GK]

Each leg is welded along all (4) mated edges; the welds will never fail. I could only find end caps in 25mm and 32mm. The RHS is 30mm. I bought the 32's on a punt that they could perhaps still be hammered in but they couldn't. I can't remember how many times I used the red clamp before the swiveling foot broke off; I've owned that clamp for ~15 years.
 

[moya034]

Assuming the welds have proper fusion, which I have every reason to believe they do, the table will last just fine forever. That said, cross braces would inhibit the ability for any flexing to occur, but for an electronics table you would not expect this, it's not as if you'll be rebuilding engines or something on top of it.

Hello everyone. I was just wondering if anyone here has ever built a workbench or desk using black pipe with floor flanges and t-joints as legs? How stable was it when completed? Did it have any wobble to it at all? How about when you leaned on it?

I am going to be building a workbench in the next couple of days and I'm trying to decide on a design. I usually use wood for everything, wood being pine 2x4's, because their cheap. Kind of. I wanted to try the black pipe method because I saw another dude online make some cool furniture using it. I like ridiculously solid and heavy furniture though.

I attached a PDF and a JPG of what I have now. Im pretty set on the design, but if you have suggestions fire away.

The woods surfaces are going to be 2" thick. The work surface will use just under 36 2x4's. I will cut them down using a table saw and then clamp and glue them together. This will be by far the largest surface I have ever made. Still trying to figure out how I'm doing to do it. The holes you see in the surfaces will be plugged.

[nanofrog]

Cool, good to see someone else in here welding.

FWIW, both of mine are welded together as well.
