Jewelry I am new to the list, so if the answer to my query is elsewhere on your site, my apologies, and I will thank you for a redirection. Cheers ![]() I agree with Marilyn.

I agree with Marilyn. Prestolite seems to be the torch most people doing jewelry start off with. If she has an oxy-acetylene welding setup she may be able to use a Y-fitting on the acetylene regulator and avoid the expense of another tank and regulator. ![]() Well, I'm going to disagree

Well, I'm going to disagree with the others this time. I don't particularly like the Prestolite torch for jewelry work as I find it too awkward in my hand due to the shape of the handle and placement of the valve. Also, I don't like a torch that doesn't allow me to adjust the mixture for lean or rich. I know that a lot of people like the Smith Little Torch for jewelry work, but I find it also limiting because it is so small. I don't find it to be large enough for melting decent amounts of metal for casting, nor is it well suited for annealing pieces of any size at all. For small pinpoint work on gold, it is the tops, however. My preference for an all-around torch for metalsmithing, from silversmithing to casting to light welding to gold work, is the small oxy/acetylene torch sold by Airco years ago for radiator work. Victor has made a similar unit over the years, too. This torch is midway between the Little Torch and a standard O/A welding torch, with tips available from 000 to #5 and even a small rosebud, plus a cutting attachment. ONe torch that is available today that is a good size and well made is the Meco "Midget" torch. It has the valves at the base of the nozzle stem where they aren't in the way and don't get knocked out of adjustment the way that valves at the base of your hand can often do. The Smith Versa Torch is the closest thing to my old Airco that is available today, I think. This torch is sold primarily for the heating and air conditioning trade, like my old Airco was sold primarily for the radiator repair trade years ago. Rich ![]() It seems to me that it would

It seems to me that it would depend on what she will do with her torch. I have several and the "Little Torch" is pretty unbeatable for things like soldering rings and soldering/fusing chain links. I like a cheap air/propane torch for reticulating and general soldering. For larger pieces annealing or fusion welding it is hard to beat a full size cutting torch... mine is propane/oxygen as that is much cheaper to run than oxy/acetylene. Heiki Seppa uses an extra large oxy/acetylene unit for reticulating higher purity gold alloys and he runs it full roar, holding the torch as much as six feet from the metal and with all drafts blocked off. For a beginner it is tough to tell what she'll end up wanting to do and thus require. I'd say Rich's versa torch answer might be a good guess or you could go with the cheap air/propane unit until she runs into a need for something different, I do quite a lot of work with mine. I have the BERNZOMATIC JTH7; http://www.bernzomatic.com/PRODUCTS/TORCHES/PROFESSIONALTORCHES/tabid/230/ctl/Detail/mid/1009/xmid/6939/xmfid/3/Default.aspx there is also a trigger start version of this available now; http://www.bernzomatic.com/PRODUCTS/TORCHES/PROFESSIONALTORCHES/tabid/230/ctl/Detail/mid/1009/xmid/6940/xmfid/3/Default.aspx ![]() You can put a finger over

You can put a finger over one of the air intake holes and change the air/gas mix but I admit your point about lean or rich. It's not as awkward to hold if you hold it like a pencil instead of an overhand grip. One grip that I have with the oxyacetylene torches is the black suet that floats through the air when you light the darn thing.

If she is going to be
If she is going to be working with silver, I recommend the PrestoLite system. It comes with tips but the flame that each tip makes is adjustable. It uses acetylene which I prefer because it is lighter than air and does not puddle in the basement if she will be working at home as I do. I think it is far more adaptable than the Little Torch which someone is sure to recommend. I think that one which uses oxygen with either propane or acetylene, is more suited to gold work.
