Cutting Hardened Steel

So here's my situation... I've lost the key to my U-lock - I'm fairly certain it fell out of my pocket while I was sitting - somewhere :/... Any recommendations on how to cut it?

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).

Protect steel without paint.

I decided to try my hand at making jewelry with a cheap piece of steel. Partly, because of price and partly due to not being able to find a large enough piece of stainless. It turned out great. However I know it will rust if I don't protect it somehow. I'd prefer not to paint it l, because of the work to buff it to a high shine. Any ideas on how to protect it from rusting when in contact with skin?

Recently got a diamond wheel for angle grinder.   tho it is marketed to cut tile, marble, etc, i tried it on steel.  cuts quick enough, but leaves huge burrs. burrs 4x thicker than the workpiece.   seems the blade just melts and squishes the steel out of the way.  it works, kinda, leaving a hazardous ragged edge on the work... i see why they dont market those blades for  steel. im reminded of friction cutting blades.

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... ;)

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.

Cleaning and tinning mild steel tube Answered

I've bought and cut some lengths of mild steel tube to make chimes for a doorbell. Mild steel has a nice ring to it, which is why I bought it instead of aluminium, but it has already started rusting, so I was thinking of tinning the tube before I build the whole thing. My question is mainly how to clean it properly before I tin it. The outside I can do with wire wool but not the inside. I was thinking of just using vinegar to etch away the rust and then give it a good wash before putting it in the tinning solution. Is this likely to work ok? Also any tips on the actual tinning process would be useful. As far as I know you just make up the solution and then put the tube in it for a set amount of time, but I've never done it before, so it would be good to hear from someone who's tried this.

How to stretch holes in a steel frame?

I ran into a glitch in rehabing an old park bench.  The wooden slats were rotted out, so I'm saving the wrought iron end frames and fitting them with new poplar slats.  I included a mid-project picture below of one of the end frames. I don't know if you can notice from the picture, the holes in the frame for mounting the slats were not in a straight line, but rather haphazardly.  So each board needs to be custom-drilled to match the mounting holes in the frames. Problem is, I originally measured the distance between the bolts on one of the old slats and used that measurement to drill ALL the new (expensive) hardwood boards.  I had made the careless assumption that the holes in the frames would be in a straight line. Never assume good workmanship! After drilling the slats, I applied about 5 coats of clear urethane spar varnish.  The new slats look supreme, and I don't want to zorkk them up by drilling a second hole in each board to match the stupid end frames.  So the only way out of the quagmire I can see is to drill the frame to match the boards.  OK! Problem is, most of the new holes in the frames would intersect the old holes, and I know that drilling an intersecting hole is problematic, especially in 3/16" steel.  So I need advice on how to stretch holes in steel into an oval shape.  I'm thinking some sort of router bit, or a grinding bit that I could use with a hand drill. Suggestions?  Thanks.

welding cast iron to mild steel

Welding cast iron to mild steel is for the most part done with ornamental iron such as gates and fences. the ornaments are typicaly cast iron such as spearpoints and fit over the top of what ever square tubing size ect you are working with. If you weld say with a mig welder in the normal mannor you rweld will cold roll and ball on you leaving a poor appearance that you will have to spend time grinding to make look good. Fortunatly it is not a matter of strenght or how much penetration ect. It is just ornamentation but must look good. Now take your mig welder with say 035 wire and use pure argon..(less spatter). Turn your welders heat up somewhat past what your normanl setting would be for what ever thickness you are using. Use breif spot welding like techniques overlapping as needed. You will find that this makes a good wash bead with no undercut or cold roll. The argon gas helps to keep down all the extra spatter welding cast iron to mild steel seems to cause. Larger peices such as caps for say 4by4 gate posts or fence posts, i preheat as uniformely as possibly to just under cherry red then weld as described. It welds badly because cast iron is actualy dirty, literaly with particles of dirt in the cheap castings, wich the ornaments are. Not haviong the need to be anealed or nodular for instance. If the welds are not going to show then you dont have to do this. It will still weld, just do not expect the clean perfect welds you are used to.  And NO I do not have PICS AND I dont own a digital camera nor do i know how to use one let alone put them on a computer.
