    Casting your own steam engine castings?

    So is Victoria, the state where I live. It is 1000 kms from east to west in a straight line and if you travel by road it is about 1300 kms.

    Using a brushless D.C. motor as a generator.

    If you want to make a generator for your model engine to run then brushless D.C. motors are very common these days. Most photocopiers and laser printers have them. Older server computers have them in their back up drives. The one I used came from a laser printer. This generator has a three phase...

    Casting your own steam engine castings?

    To melt 14 kgs of cast iron the furnace burns 8 kgs of waste motor oil and 8.8 kgs of propane. Both fuels take about the same time to melt 50 - 60 minutes.

    Sarges Workshop - Oil burning furnace and zinc casting

    This is why the bad smell is added to propane so leaks can be detected.

    Compressed air revolving cylinder engine

    Thank you so much for posting the link to your engine. I watched your video and it was really great to see another version of the rotating cylinder engine! Just a quick question, why are there so many holes drilled on the inside of the rim of the flywheel?

    Sarges Workshop - Oil burning furnace and zinc casting

    It is easy to melt iron with oil, also it is easy to melt iron with propane as well but oil is free but propane is not.

    Compressed air revolving cylinder engine

    There were many examples of this engine at N.A.M.E.S. so when I got home I liked it so much I decided to build one. This is the quickest engine I have ever built, it took 8 weeks from concept to running engine. The reason why I was in a such a hurry a local model engine show ( Melbourne...

    casting weekend

    A roof without walls can be a problem when molds can get wet from rain. If I tried to pour a mold with excess moisture it will explode so it is far safer to keep the molds away from the weather in my shed.

    casting weekend

    My cast iron melting furnace generates a lot of heat so it needs to be outside, under a roof without walls. The roof only idea lets me melt in any weather. My furnace gets cast iron very hot so there is no problem with the iron getting too cold to pour by the time I get to the sand molds.

    Generator.

    You will be amazed as to how much more output the generator will have if you put magnets in a iron housing. Here is a simple experiment you could try, use a magnet with no steel attached and see how much weight you can lift with it. Next place a thick piece of steel on the magnet and you will...

    Generator.

    I only pour iron castings for myself. Years ago I could not get foundries to make castings for myself because they did not like doing one off castings. Years later I can see why they do not pour one off castings as it takes a lot of time to make a sand mold. To me I do not care how long it takes...

    Generator.

    Thank you for watching my video. I had a look at your website and loved your generator kit! The castings are exactly the way I would make them. So many of the kits I have seen are very plain looking castings but your castings capture how generators would look 100 years ago.

    Generator.

    After visiting N.A.M.E.S. and the Henry Ford museum years ago it gave me plenty of ideas to make a generator from a electric motor. I liked the shape of the Edison generators at the Henry Ford museum so some patterns were made copying those shapes and cast them in iron. I used a garbage disposal...

    My steam engine I made casting the parts in iron.

    Yes I made the patterns, sand molds and melted the cast iron which I poured into the sand molds. I also machined all the parts for this engine.

    My steam engine I made casting the parts in iron.

    As my iron casting skills improved I designed a complex large model steam engine to see if I could do it. Three years later it burst into life so I was very happy that it was not a failure. A brushless D.C. washing machine motor was used as a generator to load up the motor. I have only run it on...

    Casting a crankshaft in iron.

    I remember talking to you about casting bronze parts for that civil war ship steam engine at N.A.M.E.S. show at Toledo. I am not sure about using Vanadium to prevent chill in cast iron? I use ferrosilicon just before I pour. Nickel, copper and aluminium can be used to prevent chill in cast...

    Casting a crankshaft in iron.

    Thanks for the reply. I would have thought that you would have perfected the ductile iron process by now? I must try to make ductile iron and see if it is as difficult as they say it is. I was very surprised how far the crankpin twisted before it broke. If you don't do a destructive test on that...
