Graphite piston material

[chucketn]

What are your sources of graphite rod for pistons? I’m building a ‘tin can stirling’ and have used a 1” steel tube for the cylinder. I need to find piston material that I can turn and lap to fit.

Also brushes out of an old DC golf cart motor I had after a rebuild.

Check out McMaster Carr's on line catalog they have it.

Art Supply Store "solid graphite" pencils. But try to get 'hard' ones, the 'soft' ones aren't much fun to machine.

When I built my three sterling's I used NAC 500 for the piston material. Its the right stuff.
