When I started out my workshop was in a cellar, ie under the house.
I put up with that for a couple of years but had to change due to the
- No daylight
2.Fume problems from the gas enamelling muffle
3.polishing dust getting everywhere
4.fumes from the fluxes and the oxy propane brazing torch. So unless
you planning to do say, only a couple of hours a week. The 1st
reccomendation is dont put your worshop in the basement. secondly the
other no no's above will affect your health.
No filtering unit that would make it a safe place to work is small
and cheap enough for your needs. If you are short of space, what I
would do is use another room upstairs? like a bed room and sleep in
the basement. Depends how badly you want to do the silversmithing.
silversmithing and jewellery making are a little different.
As you know its a question of scale. I sought out an old deserted
farm, so as to have all the space and workshops I might need. Been
here some 40 yrs. The only limitation has been my ideas and time!!
