Would a short piece of angle iron work as a bracket. You could bend out the top to make a winged -v- shape

I thought that might be the case, hence the angle iron idea. You could even use a couple of wooden wedges. I'm rubbish at diagrams but the green bit is angle iron, shaded is wood.

Just on the chain mail thing. You can successfully use sprung steel washers. Counter twist them to "open" them up and then link them up before twisting flush. And they won't pull apart like wire. It doesn't take as long as you think and you can watch tv or do something else at the same time. I might still have a bit lying around somewhere.

You could try asking around the living history/ reenactment community. There are a couple of sites that keep up lists of groups for you to find a local one.

It's pretty easy to remove galvanise using a weak citric acid solution. Citric acid is available from home brew places and is cheap and safe.

I believe you can use malt vinegar to check for the presence of magnesium, if you're planning to recycle material that's something you might consider. How are you going to melt It down?

Pretty excited about this: I've been offered access to a laser cutter on the basis I provide the dxf and the steel and they'll cut whatever I want. What do I need to consider when doing my layouts? Apparently the software can work out the lead in and lead outs but what about clearance for interlocking parts, relief cuts, that sort of thing. Kinda tempted to do a whole sheet of meccano http://www.dalefield.com/nzfmm/slap/RoyalMeccano.JPG Or some finger jointed boxes. Anyone got any other suggestion of test pieces to give me ideas?

To save you the embarrassment; do remember to use something to hold the pick while you offer it up to the grinding wheel. It will get very hot very quickly.

Ambrose Burnside posted:I'd be using it for large-scale chainmaille, not finger-rings or whatever, so if I did it that way every ring would have to be sawed open, woven into the chainweave, and welded shut again. Much faster to make the links the normal way, by winding heavy wire around a mandrel and then sawing down the length of the coil to get a couple dozen rings all at once. Spring steel washers work well using 2 pairs of pliers to twist them open then closed. Very resilient to pulling apart once done.

From my experience with the Emco FB-2 I bought you can could probably do anything, if you're patient enough... Would making your tooling in mild and case hardening the face be an option for you?

Yeah or http://www.3ders.org/articles/20150424-dutch-students-smuggle-3d-printed-knives-into-court-to-prove-a-security-flaw.html Its the same mentality that stops me taking nail clippers onto a plane then gives me steel cutlery and glass with my meal. Its a mystery. I guess it might be interesting to see what would happen if you made exotic or historical reproduction arrow tips and then plated them for hardness or plated helmets for role-playing or SCA or whatever but that's not my thing. Unless nerds would want to pay me lots of money for said lightweight plated helmets, then it might be.

Oh yeah I meant making something with the right appearance, not functionality. Elvish great helms and crowns etc. That said when you look at even a motorbike helmet it's polystyrene with a thin layer of plastic so you could possibly do something similar with polystyrene, a thick shell of ABS or Nylon with a cosmetic brush plated finish. Anyway, I'm not doing that. Tell me more about how not to die in a hydrogen explosion while I hook up batteries.

No I think they're designed to dissipate a single impact of several tons. Perhaps a better comparison then would be a riot helmet, also foam covered in rigid cover. But it's a moot point as I'm not planning to try it. Rapulum_Dei fucked around with this message at 17:07 on Apr 27, 2015 |

ANIME AKBAR posted:I'm an electrical engineer who wants to do a short production run of a gizmo I made (like 100-1000), but I'm stuck on the enclosure which is a big cost driver. Initially I was planning to go with an ABS plastic case with custom machining (I was getting quotes $7 per piece for 1000 pieces), but recently someone suggested I take a look at metal stamping instead. The plastic box is about 4.5x3.5x1.5", and would need holes on several sides, some of them tapped. I've done some googling but I'm having trouble finding examples of simple enclosures, most fabricators seem to specialize either in very small and flat parts or huge enclosures for vending machines and such, so I can't get an idea of how much this would cost. Anyone have any experience with stamping? Have you got any quotes for 3d printing? Rapulum_Dei fucked around with this message at 22:07 on May 11, 2015 |

ANIME AKBAR posted:3d printing is definitely not economical, at least not for anything beyond a few prototypes. Just the cost of the consumables would be excessive compared to the machined plastic enclosures. I'm not sure what consumables you mean, ABS filament for 3D printers is $19 for a 2lb reel, maybe less. That video of the CNC punch is a pleasure to watch, what an amazing machine.

Yeah they're a ubiquitous little job sold under loads of different names. Google 6x4 bandsaw mods to see what people have done to improve them. I got one from the for sale ads and with a bit of fettling it has served me well. I cut stops at 30 and 45 degrees and made a new stand. I was going to make a suds tray and use a fish tank pump or coolant but never got round to it.

Following on from the copper plated experiment I posted a while back I've got it dialled in a bit more and can now Nickel plate my 3d prints. I feel okay about posting it here since it really is metal. Magnetic and everything...  They both came out just as shiny. But a rub with black boot polish gives it a bit of age. The surface finish is dependant on how much prep you do before plating. In my case none. But the effect is that it looks cast which is fine for me. My next piece is a miniature ark from the Indiana Jones film. On the offchance does anyone know a good source for conductive paint that will ship to the UK? Prices seem madly expensive but I'm convinced there's some other non hobby application that will be a reasonable price. I was looking at some of the conductive aerosols intended for EMI shielding which claim to be conductive but IDK.

If you've some copper sheet handy you could use it as 'backing', The welds won't stick to it and might let you build up a layer without just punching holes. Or not, dunno but might be worth a shot.

I have this awful premonition; lying in the hospital bed, the doctors have said it'll not be long now so the grandkids have been brought in to say goodbye before it's too late. I smile and it turns into a wracking cough, hacking and wheezing before I can catch my breath again. Little Daisy takes my hand, her fingers gripping tightly. 'Is there anything You need granddaddy?' I close my eyes, lay back and think of a life well lived and the happy bitter sweet memories of my long dead wife and the joy my family has brought me. Only a single lingering regret remains, only one road untrodden. With a sigh little more than a whisper I slip away with a single word. Bridgeport

His Divine Shadow posted:Finally this hell week is coming to an end. Everyone's been laid out with this bad cold so I hadn't had time to look at my new welder or really do anything, but last night I got to it. Turns out it makes a constant annoying sound in stick mode. I thought there was something broken but consulting the manual it was the idling sound it makes in stick mode. Perhaps it's some kind of safety feature. I knew of one person who used to have the same machine and he said yes it does that, and there's a kinda whining sound when it welds too, so you can tell by ear if someone's having too long an arc. Tried it for myself and it definitely makes a different noise depending on the arc length. Way way way easier to weld with, I didn't know welding could be this easy. That's the danger of MIG. It's not too difficult to make a weld that _looks_ fine but is as effective as a bead of silicone. Weld two things together then cut through the cross section, if it doesn't look like one continuous material, it isn't really welded. Your local tec might have evening classes in welding or fabrication that would be worth a look.

You can pick up one of those generic 6x4 bandsaws for <100 second hand. They're pretty good once you fettle them a bit. Evolution make a chopsaw as well. They might even make one that flips over into a table saw too, I'm not sure.
