I am interested in locating/purchasing a soft, lubricating-"slick" grade of graphite bar stock (.75" Dia.) that would be suitable for making pistons. These pistons are for atmospheric engines and the material must be thermally stable and have a lubricating quality. These engines a made by students in the Machine Tool Technology classes I teach at a local community college.

Thank you for any assistance you can give.

There are probably lots of sources but try contacting Jerry Howell. His web site is at http://www.jerry-howell.com/ and he sells plans for several interesting model engines as well as "hard-to-find" parts kits for same. I'm pretty sure that he sells small graphite rods in those kits and may be able to advise you on a source.

Take a look at

They have quite a bit of graphite. I have done business with them in the past and have always had good results.

The source I use is National Specialty Products at (800)-677-6322. They have rods in a large variety of sizes. I use them for pistons in Stirling engines that I make. The only problem might be is that they have a $50.00 minimum (thats a lot of graphite!)
