Setting up a work area

[Neural]

While going through the sub forum with the pictures of various workspaces, I've started to ask some questions that I thought I'd throw out here and request input on from the rest of you, as most are far more experienced than I am.

I'm moving into a house in December this year.  I will have my own room for my work.  This is good.

However.  I'm obviously looking beyond just cutting cabochons these days.  I enjoy working with stone, and my passion is opals, but in order to buy more rough material, I need money.  So, the best way to do that is
A) buy rough
B) cut stones
C) make jewelry
D) give the best stuff to your wife
E) sell the rest, and
F) buy more rough. 

All the while hoping that what you sell will always be a little bit more than what your next purchase costs.

Currently what I am capable of is cutting cabochons, and mangling silver wire.  My work desk is dominated by the Genie, but has space for my dop pot and the Rascal trim saw.

But in order to move beyond just making cabochons, and into actually making jewelry, I need to do silversmithing related work.  Making bezels and attaching bails being the very basics of what I'd like to do, but I've been fascinated with the idea of making rings and such as well, so there's always room to grow. 

I've seen some videos, and read about making bezels and other silver work, and it came to my attention that there are some things going on that I had not considered in regards to how it would affect my work space.

What are the chemical hazards of working with silver?  Are there any gasses (beyond the torch) that are emitted when soldering?  Is the Pickle hazardous?  What sort of ventilation is needed for doing such work?

The room I'll have for my work is roughly 13' x 11', and has two windows (on corner walls).  It will be carpeted also.

Sorry to ramble on, but this stuff is just what runs through my mind at 1am when I can't sleep, and I like to have as much information as possible when I can.

Note: the garage isn't an option unfortunately.

Too funny... !  :D

I am not aware of any chemical hazards while working silver, nor aware of any gasses being emitted. 

Hmmm.... Is the pickle hazardous.. I don't believe so...

I have all my jewelry making things and torch set up in my living room.. It's large and I have a whole area to myself.. I have had a whiff of propane when starting out, but well.... Oh...... I dont know .. Is that hazardous??

If I get a good whiff, sometimes I can actually solder !!

I know and understand about not being able to sleep.. Sometimes my mind just will not settle down.. I start out with sheep, but end up cabbing!

Silver does emit a hazardous chemical, especially when melting.  I think it's Cadmium?  That's one of the main reasons why you should have good ventilation when you work with silver.

Here's a great PDF of all the hazards (both big and little) that should be considered when setting up a work place:

Goes to show ya what little I know..

Candmium can be fatal !  :o

I had no idea so much of the work was so dangerous. I knew pickle was not something to swim in! Thanks Akansan for the PDF... And.. torch flames are hot and can cause burns...  :o

LOL - yeah, and silver metal shavings can get in your eyes. 

Most of the stuff is just common sense - flames are hot, small metal particles are dangerous, don't drink toxic chemicals.  I knew about the cadmium because my father is constantly harping about good ventilation in any of the indoor shop ideas I have.  According to him, it's not as much of a problem unless you're melting silver. 

Two windows in your room would be easy to set up a push-pull ventilation with two fans.  Have one fan pull air in, have the other fan pull air out.  Stick your shop setup somewhere that will be in that ventilation stream.

Thanks! :)

Of all the silversmithing stuff.  Pickle, solder, flux, molten metal, crucibles, kilns, etc.  The thing I"m still scared of is the torch. :(

I used to work at a junk yard.  Used an acetylene torch for quite a long time when I worked there.  Never had a single accident or near accident involving the torch.  Always had the gasses turned on and off correctly, always held it steady and secure, but..
I still fear I'll drop it somehow. :(  
That's why these "plumbers torches" that I've been told people use bother me so much.  They are big and a big bulky and their hieght exceeds their base width quite nicely (easy to knock over).

eh.  I'm just babbling now.

Thank you all for your input.  Beyond my torch-drop-ophobia, you've settled a number of other issues that my mind was stuck on.  :)

Check out the Smith Little Torch.  It went right on my oxy-acet. outfit. I use it indoors and have carpeting. Built a neat little welding table to go with it..........Bob

I've seen the Little Torch before in catalogs.  Have wondered if it is the right tool for what I want to do.

I've been using the Smith little torch for nearly all of my metalworking needs for close to 25 years. It works admirably for my purposes. When I was teaching I had mostly the same torch for the students. I originally learned on the Prestolite torch which is an air/acetylene torch but it was tricky to get a real small flame for detailed soldering. I switched to the Smith unit because it works great for detailed work. Some people use Propane torch but a lot of fire districts prohibit use of propane (including in your barbecue unit) inside a dwelling/garage. The hazard is that propane is heavier than air and it settles to the floor and pools into an explosive mixture.
Most currently sold silver solders don't contain Cadmium because the fumes cause nerve damage. I always told my students that if they inherited any old silver solder (or got it from an old source) to discard it. There is a high likelyhood that it contains cadmium.
Use a pickle pot that has a lid ( a small, cheap crockpot works great). When you drop the hot piece into the pickle pot, tilt the back of the lid up and drop the piece into the pot from the back. This allows you to use the tilted lid as a shield from any sputters or splashes.
Most white pase fluxes have Biflourides to prevent the bubbling of the hot flux that causes your solder pallions to jump around. Some people get a red rash on their faces if they do a lot of  soldering in a poorly ventilated space (like a corner of a room). It is rare. I only had one case in my teaching experience (about 200 students) and it occurred because the student was doing a lot of soldering in the unventilated corner of their garage. Biflouride-free soldering pastes are sold by the same manufacturers that sell Biflouride pastes.
When using the polishing lathe it is advisable to wear a dust mask. DO NOT polish a chain on these machines. It will quickly grab  the chain and whip it around causing serious injury. I wouldn't let a student get near the polishing lathe with a chain without specific, detailed instructions and demonstration from me as to how to safely polish a chain. Jewelry pieces with sharp points that are aimed upward into the muslin buff will catch and cause serious damage to the piece and possible injury to you.
Have I scared everyone already?

Thanks for the info Bob. :)  Nice that a small crock pot can be used for a pickle.  those are cheap.

I'll look into the Little Torch more and see what all is needed.  I know they aren't cheap, but that is expected.

So true..

A little off topic, but Ya know .. one thing I do think about is never letting my cat out in my shop area.. Too many mineral particulates laying around..

[Bluesssman]

Mirkaba (there are too may Bobs!) would you share a picture of your welding table?

And you all have just settled something in my mind.  I've been worried about bringing my torch into my house because of the fumes.  And I admit - I've had so many horror stories about the volatility of acetylene, that I've minor nightmares of my house blowing up.  Granted, my shop is only about 5 feet from my house...

It's also good to hear that the cadmium information is probably outdated.  My dad was an Army welding instructor at Aberdeen in the late 80s, so it doesn't surprise me that things have changed since then. ;)
