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

You did it again Alberto. Recycled enough parts now to make a steam engine.
I have no doubt it will run on steam. Nice job.

Thanks for your comment. Regarding making it work with steam, I already tried it but it does not give good results. The friction of glass on glass when wet wears it down rapidly. However, working with dry air and lubricating with graphite powder, these pistons are eternal.
