  1. What kind of board are you using for soldering on? Some are more reflective of heat than others.

    I’ve also had good luck sometimes putting the piece up just a tiny bit from the soldering board, like with steel pins or scraps of old board, then bouncing the flame off the board to hit underneath.

    Personally, I HATE my tripod/screen set-up. The thin screen burned up and, I’m pretty sure, released toxic zinc fumes as well, and the heavy stuff is such a huge heat sink that soldering takes forever.

    1. That is my problem, yes,I am using a refractary fiber block at the moment (like I use in the kiln). I think this one is even worse than my “brick” (no fiber) I used to use back in the day, which I still have and stupidly I haven’t reached for it! Still, to solder bottom heavy pieces we use a kind of mess of steel wires flattened togheter, this heats the piece from the bottom very nicely, but of course you cannot pin things to it. I never saw it in any US catalog, or this German site, but I found it in the Belgian site online: http://www.buysschaert.com/CATALOGUS%20IN%20PDF%20BLADZIJDEN%20APART/136solderen%20blz%20136.pdf
      Second thing from the top. The handle seems folded against it, to use it you just fold it back. It is quite cheap and I am gonna get one in Spain, let me know if you want one to try*.
      I am also getting a coal brick now from Germany, I never used this but I read it is very nice for soldering and also to fuse little balls on it.

      I often lift the piece in a way or another to heat the bottom, but in this case the equilibrium of the “bezel” on top was a bit precarious, and only having one kind of solder wasn’t helping at the moment. That is why I had it pinned down to the brick. Now it is somewhat soldered at some points so I’ll wrap it with soldering steel wire.

      *Remember to tell me if you want any enamels too.

      Tripod/screen set up? for soldering? I really don’t know what are you talking about :D any pic?

      1. The steel “nest” thing looks great! Yes, I’d love one. (And I’ll try to get back to you about the enamels this weekend.)

        If your charcoal block is regular charcoal, it’ll help it last if you wrap it around the sides a few times with binding wire- else, they tent to crack. I generally keep one side no-flux (for fusing), and the other side with flux. The compressed charcoal blocks last a LOT better, but you can’t pin things to them. If either start to burn, put them in a metal can with a tight lid to smother the fire- water tends to weaken them. If you’re making the little balls, make a channel all around the outside of the block, about 6mm from the edge- else they roll all over the place!

        The tripod thing is number 502085 in Rio’s catalog- you can see their site, correct? Not a bad idea, but SUCH a huge heat sink!

        I usually use “Solderite” pads for soldering, and am pretty happy with them. You can’t really pin into them, though. They make softer ones, but they burn up too fast.

        1. Ok, I’ll get you a perruca (wig, we call them, lol).

          I got the regular charcoal one, yeah. My old brick is wrapped in tin and wire because it cracked (I cracked it, hehe), I could do the same with this one or just buy the metal tray for it they sell in this site too. What I was gonna do for fusing balls is to make little half-sphere holes with a round… thingy you out in the micromotor ;P so the ball stays encapsulated and forms a more perfect ball.

          The tripod looks nifty though, maybe you could ‘line’ the top of the tripod with a ring of fiber? to isolate it a bit so it doesn’t absorb the heat.

          1. I don’t think anyone sells the trays for the charcoal here- let me know how it works!

            I generally don’t do the small holes thing for granules. The really timy ones turn round anyway, especially after there’s a fine layer of ash on the surface of the block. And I rather like having a flat side on the larger ones- it makes it easier to solder/fuse them down- they don’t roll as much. :)

            With the tripod- I think it’s the screen sucking up most of the heat, not the tripod itself. The thin screens suck up less heat- but they burn up pretty fast, and I’m pretty sure release (toxic) zinc vapor when they do, since they look zinc-coated. Plus you can’t push against them at all- they’re too fragile.

            So I use heavier screen with larger holes, and that IS a heat sink. Still- it can be really nice sometimes.

            While we don’t have the “wigs” here, I’ve made nests of binding wire that can have a somewhat similar effect- it’s a technique I learned in the seminar I took that was probably the greatest class I have ever had.
