Re: Metal Pipe Gamma Type Engine

If you haven't already, I would suggest you build a tin can or soda can model while you are waiting for your class. Theory is great, but actually building a working Stirling will give you a greater understanding of the little details that make all the difference. Things like side loading torque, pl...

Re: Metal Pipe Gamma Type Engine

I signed up for classes (high school) yesterday. One of my classes will be "Welding and Machine Tool". Unfortunately, it is not until February, so my project will be placed on hold. Thanks for all your help so far, I hope to still complete it. Since I can no longer work on the engine, I wi...

Re: Metal Pipe Gamma Type Engine

I did some research and found that the lathe had an optional cross slide, and I have found pictures of them. Unfortunately, the lathe was made in 1940 and it is hard to find accessories for machines this old. I did find in my shop a drill press cross slide vise. I am wondering about jerry-rigging it...

Re: Metal Pipe Gamma Type Engine

Thanks for all your help, you have saved me quite a bit of guess work on the materials to use. I will next be trying to figure out how to polish the bore, and make a steel displacer. From a page of WoodCraft Magazine on the Delta No. 1460 (c 1939) Lathe, "...with the addition of a specialized t...

Re: Metal Pipe Gamma Type Engine

According to my father it was originally used for metal, even though the bed looks more like a wood lathe. It was made between 1940-1960, maybe back then they used that kind of bed for metal turning. "a threaded rod will not do" ---possibly, I am remaking the displacer "a brass bold d...

Re: Metal Pipe Gamma Type Engine

It might be worth mentioning that the lathe is at least 50 years old, but has worked very well for all the projects using wood I have done.

Metal Pipe Gamma Type Engine

I am working on a Gamma Type engine using metal pipes. Here is a rough work-in-progress 3D model of it. http://skfb.ly/4j3h2f1ba The Displacer Cylinder is made from two 6" long 2" pipe nipples connected at a T joint. I then have a 2" to 1.5" bushing and a 1.5" to 1" bus...

Re: "Hi" We are new here!

Hello, my pseudonym is Beauregard, and I am in high school. I do not have any industry experience, or any machining experience (again- in high school), but I do understand the basics of machines (I have worked on fixing tractors and harvesters on my grandfather's farm). I am working on a Stirling En...
