@theseanster7 There is specialized steam engine oil but that is really only necessary for larger models. For models such as this, any oil will suffice, particularly if you're only going to run them on compressed air. But even on steam, little stress is involved, run times are short and there is little or no load. So the oil serves to lubricate, of course, but mainly helps seal the piston in the cylinder, there being no piston rings. Household oil (eg, 3-In-1) or even auto oil will suffice.
@sjogge123 The basic design of an oscillator employs a spring to keep the cylinder face pressed against the steam ports. (Also acts as safety valve - used in "toy" engines.). The spring is mounted on the pivot shaft, and since this shaft is fixed to the piston, it oscillates the same as the piston. What you see moving is the retaining clip used to keep the spring on the shaft.
Thanks for the comment. If you use the recommended materials, only basic shop tools are needed - hacksaw, file, drill, soldering iron and sand paper will suffice. After all, it is a very simple engine and the designer's objective was to minimize the need for any special tooling.
Very good, very good indeed. I do have a complete machine shop at my disposal, however I was exploring the idea of making a video on building one with hand tools only. So that people that might be interested could give it a try. It is double acting right?
Sorry - it's only single acting. To make it double acting would increase complexity and likely defeat the objective of making it simple to build. Not saying it couldn't be done but I see some design problems. (That's why I made a twin-cyclinder variant rather than try and build a double acting engine.)
Two things, first could you put the link at the beginning in the description? and second, could The model engine manufacturer you referred to is not Namod it is actually Mamod
Thanks - changes made. Unfortunately, orignal web site for plans has disappeared with the close down of "Geocities". Have included reference to a few other sites with similar designs in the description.
yea. simple to make. that is so easy and it's handmade yes ;DDDDD cool engine ;)

I'm in the process of making one of these. what do you use to lubricate the cylinder?

Very nice engine, what shop equipment did you use to make it?

Thanks guy, im going to try to make the engine frome the hardware store website, thanks for leading me to it!

sweet engine man, care to teach? possibly a how-to video?
