Would it be possible to mix titanium and steel? Answered

Theoretically, could it be possible to mix titanium and steel and get the best of both? Let’s just assume that cost and difficulty are not an issue? Imagine the possible uses for a metal that was non-magnetic, non-conductive, corrosion resistant, and with a great strength to weight ratio, while being as hard as tempered steel. For one thing, it make a fantistic knife. So, the question is; Would it be possible.

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,

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.

How strong is sheet steel? I am thinking of a rugged Kindle Case?

I want to make an extremely strong case for my kindle, the kind of case where I could sit on it and not cause a problem. I'm also worried about the corners of heavy books hitting it right in the middle and breaking it through the case. I have thought about sheet steel, flattened PVC and wood. Wood adds a decent amount of thickness to be rigid enough, and I wouldn't know where to buy thin hardwood planks. PVC I don't believe is all that rigid once it's been turned into flat sheets. Sheet steel is readily and cheaply available on Ebay between 0.18mm (0.007 inches, or 36 gauge) and 1.7mm (0.06 inches, or 15 gauge), and probably higher. I don't care about the weight as much as the thinness and strength/rigidity, so I thought sheet steel might be the best option but I've never worked with it. Suggestions? Edit: I would add some sort of shock protection, ie: neoprene, but it's not dropping that I'm worried about. The design would be two flat pieces sonnected by a fabric "hinge," similar to this: http://www.amazon.com/Marware-Atlas-Kindle-Touch-Cover/dp/B005HSG3L0/ref=sr_1_6?ie=UTF8&qid;=1340375705&sr;=8-6&keywords;=kindle+case I would add raised edges surrounding the Kindle on the "bottom" piece of metal, so that the two pieces wouldn't squeeze the kindle between them when pressure was added.

welding steel near aluminum, insert wisdom here!? Answered

I have 2 pieces of aluminum that make up a kind of finger hinge.  The two sections are each 3/4" wide pipe each ending in finger joints with a hole drilled through the fingers.  A cotter pin has been used as the hinge pin during the mock up, but now a permanent hinge pin is required and due to space regulations it must be very flush and end on either side with a flat round, similar to a nails head (striking surface).  I was going to merely insert a nail, then put a tightly fitting washer over the other end, and briefly mig weld the end of the nail protruding through the washer too the washer.  The opposite end will have a small thin piece of cardboard as a temporary spacer to ensure a snug but not too tight of fit.  Of course the rest of the aluminum will be shielded from weld spatter.  The weld would then be ground flush.  There will not be a lot of tension put on this weld, but some minor vibration. There will 5 of these pipe section with 3 joints per section each, they will be very close together and require the ability to move independently from each other, so no shared pins. Will a very brief weld cause the pin/nail to heat up to a point that it causes the surrounding aluminum to melt and "horribly" cause the 2 joints to fuse? The 3/4 span is much to wide for a pop rivet and would have to much of a bump on the sides. Bolt and nut would also have to much of a bump, and introduces the destructive effects of a steel thread running through an aluminum body. Philadelphia screws are just too wide for this application Actually peening a real rivet will put to much stress on the aluminum pieces. No I do not have the means to weld aluminum, as this is a solder core wire feed welder, not a true mig. Any suggestions?  I have done similar welds before, but all pieces were steel, not mixed.

The best way to reverse staining by copper etchant in a stainless steel sink?

So I used some of the copper etchant in aqueous solution stuff (instructables example) and a couple drips got onto my sink. I was thinking there might be two ways to minimize the appearance of these stains: 1. Could I just dremel the very surface off with a fine sandpaper/stone? 2. Could I use electrolysis in a small area to try to at least pull the copper off the sink? There is some dark staining which I assume is some acid that ate through some of the steel, but the copper is the most obvious problem. I doubt there's a good method to remove what I assume is the acid staining other than trying the dremel.

Could you use a small size of Tube Metal ?

You could tack/spot weld a small size of tube steal a  (1/2" or 1")  underneath  the bottom side of the angle iron @ the 90 degree bend. This would make the Lathe rails/bed a lot stronger. Tube Steel would be the best option because it wouldn't bend or Flex like Roll Steel might. You can hold a long say a 10' piece of roll steal up and you can see it bow some. Then hold a 10' piece of Tube Steel up and compare the difference of bow in the two. Angle iron would be a second choice. PK

3d Printing aluminum? Answered

I was thinking about 3d printing aluminum and was wondering if you could do something like this. You have a stainless steel air tight cylinder, surrounded with some refreactory, then nichrome wire, then insulating refreactory. The first layer of refractory is to prevent an electric short between the wire and the stainless steel cylinder. Stainless steel so it will take longer to oxidize. You would fill the cylinder with aluminum, close it, turn on the heater, t would heat up the stainelss steel and aluminum and melt the aluminum. Temperature could be regulated. Air would go to a hole in the top of it, the air would be regulated by a solenoid valve and a a pressure release valve. A needle with come out of the bottom, however it would be bent into a upside down U shape and one side would poke out the bottom, this would preven the aluminum from running out when there wasn't pressure. When the solenoid is open, aluminum comes out, when the solenoid is closed the release valve is opened to get rid of any excess pressure and stop the aluminum flow. This would be put in the place of the the traditional extruder, would this work?
