Hi Peter
Don't think I've seen your completed mill engine running like all of your engines its looks very good, i always have a big grin when I see one of my engines designs completed and running.
I noticed a few comments regarding the drawings and copyright issues, I designed the engine to encourage newcomers to the hobby and to that end I'm quite happy for the drawings to be passed around and shared, I gave permission for Jewels to draw the engine up in 3D cad and to make his drawing public. As a word of warning to anyone contemplating using Jewels' drawing to build an engine:- they were created as a drawing exercise not as working drawings Jewels has put his own interpretations into his drawings making some aspects of it confusing, so for any one contemplating making this engine I would suggest they get hold of a copy of my drawings they are far more user friendly.
Keep Modelling
