I have been doing a bit of research on building a low temperature Stirling engine, and I came across this website,
http://heetgasmodelbouw.ridders.nu/Webpaginas/pagina_koffiekop_jan/koffiejan_frameset.htm
The design on this website looks nice, and I would like to give it a go (after I build a simpler model), but I have my doubts about the following statement within the instructions.
Any thoughts on this? I understand oil could be a bit viscous, but it wouldn't seem to be so dramatic that you would want to run this engine dry.
*EDIT* Be sure to hit the "English" button at the very top of the webpage.

Never oil the working piston in the cylinder! Even very thin oil is more or less viscous and increases the friction. Mind that the power of this type of Stirling models is very low so little friction can be fatal.
