Cal Lane's steel lace

The photo of this cut-steel lacework make me want to run out to the shop, grab the torch & some scrap steel, and start carving. Cal Lane cuts shovels into lace, oil drums into tapestry, and I-beams into filigreed sculpture with incredible delicacy. From the New York Times article: "The work is about the contrasts between the industrial and the fanciful, the opaque and the transparent. Ms. Lane described herself as "a person who always has opposites in my head."She started her adult life as a hairdresser (her mother owned a salon in Victoria), but she said she was a tomboy and "welding seemed to fit me better." The mix of feminine and masculine vocations (teasing hair and welding steel), she said, is encapsulated in her work."Check out more of Lane's work here and here. Amazing.

Uses for a K'nex steel rod?

So I own a 39.1 cm (15.4 in) K'nex steel rod, which I got from the 6 ft. Knex Ferris Wheel set. Does anybody know any good uses for this rod? I should point out it is slightly thicker than the typical K'nex rod, has no places to clip on connectors (other than on the ends) and creates a lot of friction with the holes in connectors (so no epic single shots unfortunately). The rod is also quite heavy. The picture is a comparison between the steel rod and a strengthened grey rod (black).

Stainless steel. Minimum PSI rating?

G'day I have done the obvious searches, with no luck... So I was wondering.... Does anyone know if stainless steel tubing, has a minimum standard PSI rating? I ask this because today at work I found a hidden stash of old Stainless tubing.... It's cheap because it isn't a carried line anymore.... But the manufacturer or any trace of packaging/PSI is long since gone.... I'm talking $8 AU for a 6metre length of 16mm Stainless with a wall thickness of 1mm, and $12 for a 6m of 30mm .... Is there anyway of telling what PSI rating, it would have from the gauge or internal seam..? I am aware that most stainless for pressure is generally around your 1000PSI+ mark, just wanted to query you knowledgable folk, before using it for high PSI... I would appreciate any help, because I can't hide these lil' babies much longer.... There is about 15 length's of each... Thank in advance... ;)

What do I do with all this cable?

So my dad often brings home scrap wood and the sort from his job but recently he has been doing something or other with stainless steel cable, cutting it up for whatever. Anyway, I now find myself with at least 50 pieces of this high quality stainless steel cable that is just thinner than what I have to tie out my dog. I'm not sure what size it is, but I counted around 20 strands on one of the frayed cuts. It all averages about 4-5 feet, but it ranges from a few 1 foot sections to quite a few ~6 feet sections.  I would love to find a way to put this all to use in a clever way, but who knows how long it might be before I think of something myself? My first instinct: Ask Instructables! If you have any ideas at all, please leave a comment as to what I might do with this. I'm going to ask my friends as well but I bet some of the more experienced people here might have some good suggestions.  Something I would like to know is what is the best way to link these together, if I want something longer?  Any suggestions welcome, thanks.

Reduce steel tube diameter by 0.3mm Answered

I am trying to make a DIY CNC machine, using linear rails and the expert advice in the many awesome instructables out there on this topic.  I hit my first roadblock, and I need some help/advice please... The 16mm steel tubes I ordered for the sliding rails wouldn't fit in the 16mm linear slide bearings SCS16LUU that I ordered, they are ever so slightly too big. With a lot of force I could get the rail in the bearing, but it wouldn't slide without extreme force - certainly not the smooth sliding motion it's supposed to be! I've probably ruined the bearings by forcing it in, but I'm not worried about that so much right now (I have spare bearings). I broke out the digital callipers, and the rail diameter measured 16.3mm - that's .3mm more than expected, and more than can fit in the 16.0mm bearings. So now I need to reduce the steel rails by 0.3mm. I have only hand tools at my disposal, and no experience accurately reducing steel rod diameter. I guess another alternative is increasing the slide bearing diameter, but these are sealed bearing units and difficult to get at. Does anyone have any ideas ?  Would it be easier to order new steel? Please let me know any thoughts on this, I'm desperate here.  Thanks in advance,

Heating options for hot bueing steel?

After moving house I am still living in a big mess of boxes that need to be unpacked, kitchen stuff be sorted and and so on... But with a big garage and proper workspace at hand it is also time to consider my options on how to create my tinker space. I would like set up a small forge later on if the landlord gives permission and that means bot blueing steel again. Which brings me to the problem of heating the nitrates :( My last setup was not only on a different continent but also totally oversized and powered by three big gas burners. This time I would like to go a bit smaller so I can use it inside the workshop. Was thinking of a max of around 8kg of nitrates that need to be heated in a safe way to melting point. Problem with that stuff is that it is not only highly corrosive but also requires quite some time and energy to melt. Using gas on such a small scale seems far to dangerous uless I include baffle plates and add several safe guards, so I would like to avoid the open flame approach here. Only reasonabe alternative that comes to my mind is electric heating. Did some small test last night outside :( Used a 2000W electric hotplate and an old stainless steel pot with about 1kg of nitrate in it. After 40 minutes there was still no real melting happening despited the entire thing padded and covered in glass wool. 20 minutes later I turned it all off and once cooled I found that only about 1cm of solid nitrate was at the bottom. If I would use a suitable container of let's say 20x10x10 cm as a small melting vessel: Could it be sufficient to use a 2000W nichrome heating element (with temp controller of course) in an insulated, forge like setup to melt the nitrate ina reasonable amount of time and be able to keep it that way once the steel is dropped in? Problem is the entire garage is already setup with power outlets and they all go to a single 10 amp breaker. I could max it out with 2400W but for obvious reasons would prefer to have some juice left for lights and other uses. If anyone here already made such a thing it would be great to hear how you solved the heating problem without waiting half a day for the stuff to melt.
