      Rick just gave you some excellent suggestions. If you're worried about neighbors and thinking "stealth," you can't do better than electric. If (when) you're discovered, electric will also sit better with the local fire marshal, should he become involved, than propane. However, if you plan to step up from aluminum to bronze, you will quickly leave electric behind. That said, your neighbors don't need to know that you have a small gas fired furnace, if you simply don't update them after transferring to propane.

      It may take a couple of years before your neighbors get wind of what you're doing, but they will, regardless of how quiet you are about it. Some people live to stick their noses where they don't belong, and those same people also love to wag their tongues. If you only do occasional projects, you might last five years before everyone knows your business.

      This brings up the timely subject of furnace size. The larger your furnace, the more tongues will wag; the smaller the less. There are coffee-can furnaces, which don't upset visitors like large furnaces do (oh look George; isn't that just the cutest thing you ever saw?); its the difference between fascination and worry. You won't be making much tooling with a C-C furnace, though. The next larger couple of furnace sizes (two and five gallon respectively) are quite stealthy if someone has carefully misdirected his neighbors with a coffee-can furnace first...

      You should know that smell from a properly working gas fired furnace is nil; noise is a different matter. Well built burners are nowhere near as noisy as old styles, and there noise is pretty well absorbed by the furnace interior; however, the exit hole can become a lessor source of noise, UNLESS you make the opening extra large and cover it with a baffle plate (6" diameter circular kiln shelf, held at about one-inch above exit).

      Can't go much further without questions from you.

      Subject: [hobbicast] Finding my Way.

      I have just joined this forum so I guess I'd better introduce myself :-

      Having recently retired from engineering ("hands on"), and having

      recovered after being hospitalised a lot in the last 2 years or so, I am

      now finding that I miss everything, so I'm attempting to set up a home

      workshop in one side of my garage, hoping to try all the crazy stuff I

      thought up in the last 50 years or so - it may not get past the planning

      stage with some projects, but it'll all be fun, ie. so long as my body

      can keep up with my mind!

      I have always been interested in casting since I had the opportunity

      (for an all too brief period) to design and make foundry patterns and

      coreboxes for industrial valves, but never found the time to try actual


      Now I'm living in an area, quite close to other people so I want to be

      careful not to annoy my neighbours and get myself completely banned from

      doing any foundry work - the legality debate is something I don't want

      to even think about! - I think that barking dogs would probably get more

      sympathy than I would if I got on the wrong side of the neighbours!

      So, I really have to think carefully about what sort of furnace type to

      use, whether to bake my cores or to use the Co2 method for hardening,

      anything which will not draw too much attention to my efforts, (or draw

      too much from my wallet! ).I will probably start with aluminium (as you

      do), but possibly move on to bronze and even iron!

      No doubt all this has been discussed many times before in other threads,

      but as I said, I'm new here and I will welcome any sensible suggestions.

      PS. I will be away this weekend so may not be able to reply till Monday,
