I hate seeing steam engines running too fast, Yours is running at a lovelly speed , well done
 
Did you design it yourself and if so will you be making the drawings available. Thats one I would like to try myself
 
It's a modified Elmers #29 mine engine (4 psi). The flywheel runs 2.5 x faster than the main shaft so the increased stored energy allows improved low speed operation. The next one will have a planetary drive coupled to the flywheel (~6:1) to enable very low speed.
I thought I'd seen the design before. Great work it looks a lovely little engine and very smooth.
