What type of "heating" is best to use for the ring expansion process?
1282421
Did not need any heating. You just hammer it in and it expands over time - I kept it on for 10 days and it expanded 1 size.

I have no idea. I thought it was for simple small enlargements that could be hammered out using a rawhide mallet.

It's a good idea to anneal the ring before stretching. You can use a propane or butane torch to achieve this. Be very careful if you're when annealing silver/gold because if you heat them for too long/too high of a temperature it can permanently ruin the surface of the metal. The basic rule is that when the flame around the ring turns from a blue to orange it's time to drop it into a bath of room temperature or cold water. Then you start stretching. I've used this method to stretch a silver ring from a size 7 to size 11 3/4 in one shot. Although it might be a good idea to anneal it for every size up it goes.

Many use a small rod curling iron. Myself I like using a small soldering gun w/ interchanging heads & a steel ruler as a guide for a straight line. Practice on scraps or a bag that can't be used. It doesn't take long for the soldering iron to make the seal. I leave enough space for the vaccum hose to remove the air then using a finger below the hose when done to stop air from re-entering the bag & finish sealing the bag. Don't burn your finger. I have also used a bag clip during this process, the one that has a ridge that snaps inside itself. Hope this helps.

you can also use a hot knife or soldering iron. less chance of burning and very neat ends.

You can try a 4mm 7018 with the machine maxed out at 160amps, but it will be hard to start and will probably leave a crowned up weld bead. If you are going to try 4mm rods, I would make sure that they are fresh from the rod-oven(set to 120C') and also to preheat your workpiece to around 65C' if it is 6mm or thicker. As Jose says though, you will have better results a with 1/8" 7018 or 3.2mm...not sure what amps to use for metric sized rods. I weld my 1/8th" 7018 between 120-140 amps depending upon position. Good luck and "Have a Good Time with your Hood Time"

Not sure, but I wouldn't think that is a great option. Have you considered using heat-shrinkable tubing?

Not easily. I usually 'catch' the lip of the ring with pongs of a fork and try to maneuver it, or just get some warm fingers. its a bit tricky. there might be a better option/tool but I havent figured it out yet.

Yes, with certain materials. A higher than 4% silver solder (40%, for example) may require an open, hotter flame to solder. Go to Youtube and search "How to solder jump rings with Dremel Versitip" for an excellent demonstration.

I will start with saying that I am NOT a jeweler. Here is what I do. Put the ring on the mandrel. Put a piece of PVC pipe on top of the ring. Use a rubber mallet and tap the PVC pipe, pushing the ring down the mandrel. The PVC pipe provides even pressure all the way around so that the ring doesn't get wonky. Tap the ring to about one size smaller than you want it to be then turn the ring over and finish to the proper size. Do this so the ring doesn't take on a cone shape. I will end this with I am NOT a jeweler, just a hobby ring maker. I have not yet mastered any part of this, but this seems to work best for me. There are presses made that are more advanced and easier, but much more expensive. Hope this helps.

Use pex type rings found at any major hardware store. I prefer to use copper, but there are other composites out there too. Make sure you look for the PEX

it heats it very well from cold to hot .However it has a coil inside that might corode in time >I would go with Magic Mill instead

No, you need to go to a Lowes or Home Depot and purchase a tool for just stainless rings. If you are doing work inside in a dry area copper will work. Outside go stainless for sure. I bought the crimp tool for copper and sent it back based on the plumber advising me. He lent me his stainless crimper unit. Units are about the same at Amazon as are the stores. it is a great system to replace copper tubing. Enjoy.

You can one of two things! What I did was, blew up the our ring with my mouth! Only because I forgot my air pump. But you can use a air pump from a air mattress, and use the larger adaptor for the ring, I hope this helped. I use this pool as a baptismal and it works quit well for me.

Try running just the ring area under hot water. The heat will expand the ring, maybe loosening the threads. Use a towel to protect your hand after removing it from the hot water and to get a better grip of the metal ring. Once removed, inspect the threads for signs of "galling" caused by metal fragments fusing between the threads. The company may exchange your press if the threads have been damaged. Good luck and be careful.

The recommended method is to add Hot water to pot. I would think that is the safest method.

I use the Nordic on all size electric burners. It instructs to turn the heat to medium after achieving full heat. This is important to prevent warping. Only one per pkg. Beware - treated with something that smells terrible until it burns off.

An autoclave would be best, followed by a pressure cooker. The rubber seal seems like it would hold up to the heat/steam but that's purely a guess. Have not tried it personally.

One is best. I have not tried more but I suppose 2 is max otherwise te eg becomes too thick and te the bottom might over cook before the top gets done or solidifies necessarily for the ring removal and flipping
