Sorry about the long absence, but there were exams and stuff to deal with, then I didn't make much of anything i felt the need to post for a while, but yesterday, while playing around, I found the answer to a problem thatâs been weighing on my mind for a while: Inlaying.
Iâve never really been clear on how its done, and no one wanted to tell me, so I had to work it out for myself.
These little steel things are easy enough to make, as long as youâve got the heat, so let's begin.
Step 1: Cut the Steel to Size.
Step 2: Clean and Drill the Steel
Once the steel's clean and bright, round the corners off with the file. (did I say you needed a file?)
By now, the steel should be cleaned to its bright surface and rounded on the edges.
Now comes the drilling bit.
You need to drill holes part way through the steel, but not all the way. If you drill all the way through, the liquid metal you're going to apply will dribble out of the holes. Bad. If you evanime a drill bit, you'll see that there's a point at which the head of the bit meets the body. You should be looking for the angle between the bit that does the cutting and the straight body. If you know what I mean by that, then you should understand what I mean when I tell you that you need to drill a hole 1MM deep from that point. I udes bits of varying sizes for these holes, to give a more random appearance.
Step 3: Apply the Alloy
Once you've put the metal on, put some flux on. My brazing rod came already fluxed, so I used the bits that fell off. Other fluxes include, but are not limited to borax, commercial brazing and silver-soldering fluxes, etc. Use the right flux for the right metal for optimal results.
Step 4: The Fun Part: Melting.
Nope, it sort of spreads out into a metallic soup, moving hwere it wants to move. Don't be surprised if you have to put more alloy on. (this is where brazing rods come in useful. your hand doesn't actually go near the heat)
Once you're satisfied that all hte holes are full of metal, and that it's not going to escape anywhere, go and get a drink, or something. By the time you come back, the metal should be cool enough to proceed to the next step. I don't recommend waiting 'til the metal's solidified then quenching the steel in water. Stuff contracts when it cools, and the forces of contraction MIGHT i say might be strong enough to pop a plug of alloy out. Wait for it to cool on its own.
Step 5: Files Away!
Step 6: Finishing Up
i reckon 280 grit sandpaper's fine enough for these, but you might think otherwise. Once you've sandpapered it to the point that suits you, wipe the surface with meths. Meths, not meth.
METHS WARNING: 's almost pure alcohol, the only part of it that isn't alcohol is purple dye and some offensive chemical. Consuming meths makes you blind, mad then dead, in that order at roughly that speed. (maybe a bit slower...) It's the methanol content that does that.
Anyway, wipe the surface of the steel with a meths-y cloth to get all the finger oils off. Wait for the alcohol to dry, then apply a cold bluing solution. The bluing solution discolours the steel, leaving the copper-based alloy still bright. Actuially, i've found that the bluing solution CAN attack the alloy, if left for long enough. Bluing once is enough. Bluing twice is a waste of time, really. Bluing three time can attack the copper alloy, and you'd need to go back to the sandpaper to get rid of that.
One last thing. Apply a thin coat of light oil to the piece, to add an extra depth of shine.
Step 7: Bonus Material
But what about silver-based alloys?
Well, i tried silver solder, and it makes a nice pink-ish coloured dot. I reckon that's because of the copper content.
Sterling silver looks good, the dots look like stars in the sky on blued steel, very nice, though it does have a tendency to not stick very well.
The only way to see what works well and what doesn't is to try it. I tried having different metals in each hole. Remember the metallic soup I mentioned earlier? All the dots came out the same light-silver-y-copper-y colour.
MORE BONUS MATERIAL FROM OUR BELOVED COMRADE LEADER, COMRADES!
I made one of these and gave it to one of the kids who lives in the street. The next thing i knew, he'd got all his 6-year-old communist mates around, all of whom were demanding one. In shapes as complicated as a HEXAGON!11!!(shift+1) I did my best to keep up, but they keep coming. HOW MANY SMALL BLONDE COMMUNIST CHILDREN CAN THERE BE!?
On a much more lucid side, thanks for reading, and i'll have some mroe stuff along soon, i hope. I'll try not to leave as huuge a gap between this one and the next one.
