I have a length of steel box section, 80mm x 80mm, 3.6mm thick which is 4m in length. I want to put something onto it, in the centre that weighs 900kg. I want to know how to calculate whether this is possible but am unsure how to do it. I really want to know the maximum amount of weight I can put on before it breaks.
Every time I'm in Austin, I enjoy driving around and looking at the unique signage of various local businesses, signs which are often works of art in steel, paint and neon or bulbs. Las Vegas, of course, has the most epic signage (and even a graveyard for signs of deceased businesses), and I've been impressed with many of the googie-styled artifacts while visiting LA. On the contrary, every time I'm in my hometown, I'm saddened by the way the custom steel signs of the past have given way to illuminated plastic rectangles. What other cities have large numbers of amazing, steel-fashioned, illuminated signs?
I've been looking for interesting vintage-ish hardtail mountain bike frames, and found an ad on Craigslist for an aluminum MTB purportedly built by Colin Laing. Laing is known as a master steelworker who traditionally built beautifully-lugged track and road bikes in England and Arizona, so my hackles have been raised. It would certainly be a unique bike were it built by him. Would you be so well-informed as to confirm or deny the plausibility that this is a Neat Bike? [more inside]

I play an Array Mbira. The tines are made of spring steel. I have sweaty hands, so the tines tend to rust unless I coat them with oil. The folks who make the instrument recommend 3-In-One Oil, which is what I've been using. Does it contain anything toxic? Are there other oils I could use to protect the tines? [more inside]

I want to make sculpture with repurposed sheet steel, say 10 to 20 gauge. Probably from old cars, which is on the thin end of that spectrum, but I'd like a little leeway. Tired of waiting for my friend's friend to loan me a plasma cutter, so I'm (gulp) shopping. Do I need the $1400 Powermax 30 or will I be satisfied with the RAMSOND CUT50DY on sale for $500? The guy at the shop I called recommended the $1400 Miller Spectrum 375 X-Treme, which is about when I realized I'm in over my head. What about the $800 Hobart Airforce 500534 250ci, which, unlike the others, includes a built in air compressor? I'm not rich, and this is not for heavy industrial use, but I'd very much like something that works and works well on 120v current. I may well be using this on the sidewalk in front of my apartment, so I'd like it to be relatively portable. Also I'd rather it didn't kill me or anyone else. Merci bien!
Desperately need to find the pedal steel guitarists' prayer! Well, it's not really desperate, but would really like to.
Where can I find the pedal steel guitar player's prayer, an humorous, obscure poem only relevant to pedal steel guitarists? I am sure I've seen it on the web somewhere at some point in the not-too-distant past, but my google-fu has failed me.
Is there a good reason that we use (in the U.S.) porcelain toilets almost exclusively instead of another material, particularly stainless steel? Stainless steel is lighter than porcelain, isn't it? So I would think it would be cheaper to ship and easier to clean, making it a no-brainer green solution.

Can anyone offer suggestions on how to extend / enhance performance of Silicon Carbide Convolute Wheels? I am using a pedestal grinder to deburr stainless steel parts we've manufactured. I am using Klingspor 8" hard wheels. We just put a new wheel on & it didn't take very long for the wheel to get out of round/ deformed. It becomes difficult to hold the part to deburr it- shaking/ wobbling. What am I doing wrong? How can I improve things?
I have several projects (furniture, doors) using steel. Painting them does not interest me; I like rougher, more transparent finishes. In the past, I have used clear varnish to protect against rust. Am looking for new ideas. Wax? Has anyone tried grinding and finishing?

Giant erector set filter: I am looking for fittings used to join square tubular steel in various ways without welding, for purposes similar to a large erector set.

I'm looking for straight splice joints, T, L, X, and 45 degree angles. [more inside]

Need a full new suite of kitchen appliances, would like some recommendations. Got some prices on some Electrolux models today that looked great, but some quick research on the web doesn't leave me so confident. Is this a case of the squeaky wheel complaining online and they're actually a solid product? Or should I be worried. I'm looking for all stainless steel appliances: fridge with ice-maker, slide-in stove, dishwasher, and range-hood microwave. Specifically I'm looking for a large fridge and electric stove I'm in Canada if that makes a difference.

I have a stainless steel fridge and a toddler who is learning to walk. I want to mount a sheet of plexiglas over the bottom portion of the door to prevent it from getting dented. I would like this to look decent and be non-permanent so I can remove it when we eventually move. Any ideas on how I could do this? All I can think of is using some kind of tape, but I think that would sag after a while. Bonus for suggestions on how to also stick stuff to the plexiglas so that I can post up my kid's artwork (the stainless steel is non-magnetic).
