I can't seem to access the "How to age brass" section

Can someone help me out?

What kind of patina are you looking for?

I'm looking just to rust the normal brass tubes (shiny brownish) to something unexpected,

but also maybe someone should have a look on the script of the "spoiler" button on "how to age button", I can't seem to get it to open

Thankyou,
A

P.S. Btw your laser and radioactive pins are awesome in real life :D

You can't rust brass but you can corrode it or oxidize it, spray it with salt water to turn it green and other weird colours which old brass/copper turns with time.

The key to making that work is to do as little as possible to the brass, keep it damp with salty water for a little while; re-spray it when it dries out over the course of a few days, then leave it, do nothing, don't even touch it for a few days. Don't touch it while the water is on it either, the brass I've fiddled with and poked around didn't oxidize nearly as well as the stuff I just left with some salty water on.

Thankyou for such kind advice,

I will keep that in mind,

I found this quick and easy tutorial on EPBOT on how to make gauges for steampunk projects.  Thought it might be useful to some here.

Hi, it's me again ;) How can I drill holes into bone? I suppose I could just try, but I want to get it right in one go ;)

Not sure if this is too late to help, but I got a bit of experience in this when I made bone scales for a straight razor.

There's nothing too elaborate with my technique.  I use a vice and a hand (not electric) drill with a new, sharp bit. 

  * Clamp the piece firmly to ensure it doesn't move.
  * Mark the spot you want to drill with a scribe or punch to keep the bit from walking as it turns.
  * Press the bit against the marked spot and begin turning it, using steady, consistent pressure.  Bone can be fragile, so there's no need to use a lot of pressure if you can avoid doing so.
  * If the hole you need is fairly big, use gradually larger bits until you reach the correct size.

There's a couple of benefits to drilling the holes in this somewhat old-fashioned way.  You can easily control the progress of the bit through the material, and you tend to avoid the "burning hair" stench that often occurs when drilling bone with a high-speed drill.

Hope this helps,

- Mark

That does help, actually :) What kind of bit did you use? One meant for metal, or...?

I use a good, basic woodworking bit.  Bone isn't terribly hard, unless you're working with fossilized stuff.

A clean, sharp woodworking bit will easily cut through bone, even with a hand drill.

It only takes ONE time burning a bone with a high-speed drill to help you learn to do the work slowly by hand or in a well-ventilated area.  Better yet, outside.  Bone can STINK if it's worked too fast.  You may still get some smell with the hand drill, but not nearly what you would with the electric one.

Duly noted :-) I think I know enough; thanks!

I didn't see it in here, and maybe i'm not looking properly or in the right place but I'm about to start ..."torch soldering" some copper tubing together for a wine glass chandlier to hang above my bar.  Is there a tutorial on here for how to fit brass piping together to make it water tight? I plan on having liquor bottles upside down on top of the wine glass rack and a spigot to dispense various whiskey's.  ???

Without wishing to derail Jemamus' question (reply #112), I should like to offer here, my method for making slightly mad spectacles:

Copper and brass tubing can be soldered to make water tight joints - after all that is what it was mostly designed to do! However, if I read your post correctly you intend to pass alcohol through the said pipes. I would be less happy about this despite the use of copper vessels in distilling. I think you will find that when used for spirits, copper and brass are 'tinned' on the inside surfaces and I mean, with real tin. If it was me, I would scrap the whole idea and use the copper pipe as an outer structural, decorative skin. Then run small bore, food quality plastic pipe through it and use matching plastic spigots. I am sure these are available, even if it means raiding the home aquarium store!

umm that sausage thing isnt very steampunk hahaha ;D but I'll make a new section for it - "not very steampunk" ;)
the rest are great :) thanks and I hope there many more from everyone!

You impune the steamyness of my sausage?

Wow, not a lot of action here lately.

I discovered quite accidentally today an easy way to simulate a faux cast iron texture with just regular spray paint. In hindsight I don't know why I didn't think of it before.

1. Spray object with texture paint, the kind used to add fake stone textures on objects.

2. Once its dry, overspray with matte black. That's it. :)

3. Mist with a little reddish brown if you want to add a hint of rust.

Okay, so I'm not sure about this since I've yet to try it; however, I read somewhere that vinegar also speeds up the aging process of brass.

Also, rather kerfuddled at the idea of reanimating a sausage...
