My advice, buy the book on setting up a home shop foundry by Dave Gingery... shoudl be available at most tool houses like Busy Bee...

all my home made engines get steel liners or cast iron.
Chroming is in the works, have had the set up for 3 years but no time to perfect it....

I can endorse Andrew's recommendation on the Gingery series of books on foundries and building machine tools. I got my books from a company called Lindsay Publications - which has a huge number of books on various topics.
I built the Gingery foundry and converted it to propane (charcoal took to long). Build his lathe (lots of castings there) and a friend built the milling machine, which he gave to me when he bought a commercial one. The furnace on propane had enough heat to melt bronze, but boy was that hot!!! Had to stay a long way from the crucible. Sure got funny looks from the neighbours when I lit the furnace in the backyard. Sounded like a jet engine. Haven't cast anything since we moved but planning to set the foundry back up once I get my new shop built this spring. cheers Jeff |

I too converted mine to propane, with a burner design made from black pipe fittings, that I found plans for on the internet.
But, the charcoal was SO much more exciting... just a bit more messy and hard to control temps and timing was everything. After running out of charcoal a few times during a melt session, I gave up on that. I also bought my books through Lindsay Technical Books, and I have dealt with them a number of times. Excellent service, and great books for tinkerers..... As for melting brass/bronze - thats in my plan of things to do, sometime soon.

Yup the charcoal was very exciting, but as you say sometimes had to add coal in the middle of a melt which could be a pain. The sparks out the hole in the lid were neat though. You forgot to mention "clinkers". Read about them in books about steam ships, etc but never saw any until I built the foundry.
My twyre (SP) is made from pipe which I heated in the coal foundry and then hammered a "waist" into it. A small piece of pipe was welded into a hole at that point for the gas hook up. Would send some pictures but its in the back of the shed under 3 feet of snow waiting for spring. Anyone interested here is the web site for Lindsay http://www.lindsaybks.com/HomePage.html Hadn't visited in years but your topic got me thinking so I went and looked today. Bought a book on making crucibles) Jeff |

Andrew, that’s really phenomenal. I am impressed. There is also a guy here who made a scratch built large scale gas engine, 52cc. He turned the complete engine. He also designed and built his own two stage ignition module for the engine. I just bought a new 10X18 lathe and the new Machinery's Handbook 26th edition. I am hoping to master the art of machining with the help of the experts here I am, by profession, an electronic technician and currently the owner of a small company. We specialize in satellite communication. I have built some RC products some of which I lately started selling.
Andrew it’s nice to see guys like you sharing your interests and expertise. Great work. Thanks, Striker.

I also make stuff for sale, to support my hobby. I machine parts for engines, and diesel conversion heads. I also do a lot of castings for antique engines. Its fun to have a hobby (metalworking) that helps support another hobby (modeling) !! But it sure takes time, and more importantly effort. I am allways workinf on something new to try and get fellows interested in buying
