Good, very good, because imagine how much work went into it for that speed. A question? You make this piston and piston as it built? it stops to be a good seal.
Ok more testing reveals that the fine steel wool that is used for cooling within the backend cylinder detoriates with the heat eventually, which slows down the rpms, will look at other materials like ceramics for cooling and resistance to heat.
ok tested with longer backend tube, but runs slower 300 to 400rpm
I have made another single piston engine, same as the one you see here, but this time filled the end cap with SS wool, to narrow down the heat gap within the tube to about 5 to 10mm, this makes it run reliably. As I noticed it would slow down to 700 rpm and then speed up again, so closing the gap is important, concentrates the heat in one specific area.
