Check with Marin Metalwork on San Rafael (on Irwin
st).. They handle few very specific works for me.. Mostly time they're not happy to work with stainless (they're not handle chandelier work for example) But if you need something different, these guys can handle everything you need. They're very knowledgeable and have any single
machine you can need it.
Precise address slip from my mind but I'm sure you can find it on yellow pages or google
Now if you need chandelier work Svendson on Alameda is a very good place.. on the expensive part of the equation...
