      Loved your posting; so much information in a few sentences. "...smelly and loud..." versus "...melt(s) aluminum very fast". Helped me to finally sum up my feelings on used oil furnaces after years of just dismissing them out of hand.

      I've never become interested in electric furnaces, simply because of where I live. Seattle has confiscatory electric rates for home owners who use anything over an arbitrary minimum. But for anyone with the right background, who lives in an area with sensible utility companies, I would recommend going with one, at least to start with.

      I'm a retired EE and live in a neighborhood with a very strict Home Owner's

      Association. The neighbors I know are all very nice and would not mind if

      they knew I have a foundry but I've never met the people behind us.

      I too was concerned about being "found out" when I do casting. My solution

      was to go with an electric furnace. The power controller only switches on

      "zero crossings" to minimize any radio interference. It certainly helps that

      we have block walls around the backyard about 6' tall. I used to have a

      charcoal furnace and it would be hard to detect. I've been around used oil

      furnaces and they were smelly and loud. However, they sure do melt aluminum


      I only cast aluminum although ZA-12 melts at a lower temperature so I'm sure

      I could do that too. No interest in bronze and certainly not iron.

      Not sure where you are in your journey but the Gingery series is a great

      place to start. I've built the drill press and shaper. No better way to

      learn and have fun to boot.

      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


      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 casting.

      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,
