Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Like Komet I have always had several sizes of larger graphite yarn in the tool box.  There was always a size when pulled apart that would work well.  For over 25 years I had lots of large scale steam engines with all sorts and sizes of valves, cylinders etc and now just smaller stuff, the yarn I have still is just fine.  I like having a selection to find a piece that works fine for what needs fixing
