10 forum posts 8 photos | I'm getting close to finishing this steam engine (Which I started in 1959-60!! - Is this a record?). What should I use for a piston ring/seal and I can't find a flywheel - 4 1/4" diameter to fit a 5/16" crank. Any help or advice appreciated |

Perseus was the cast version of Theseus so the flywheel from that can be used, will clean up to about 4 1/8" and the hub is plenty large enough for a 5/16" shaft
Both can be purchased from Reeves Edited By JasonB on 19/02/2016 07:27:28 |

![]() 910 forum posts 197 photos | Brings back happy times at Acomb Secondary Modern School when our metalwork teacher let me make Theseus. It's a grand feeling when you first have it running I also made a simple boiler at school for it and was always cadging methylated spirit from the woodwork teacher. H & S seemed to be non existent then a time of life that made me interested in all mechanical things. Just seen you require a flywheel the one I found was from Stuart Turner don't know if still available. Edited By Windy on 19/02/2016 11:02:53 |

10 forum posts 8 photos | Hi all, Thank you for your quick responses. Not sure if I have to respond to individual posts, but I'll try all this time... Thanks JasonB; I have never heard of Grafite Yard, so will check on the link and I did need it for the rod glands as well. For the flywheel - a complete or just a rough cast will do. Thanks Neil: I have been reading your magazine (MEW) for the last few months. I used to discribe myself as a "real" engineer - Now I'm not so sure, having seen and read the articles discribing amazing engineering skills! Hi Windy, yes I went to Secondary Modern School in Harwich (1957 -62) and half day metalwork lessons were a joy and set me up for a Halton Apprenticeship. Now approaching 70 (next month), I thought I better get a move on to finish this steam engine! Peter |
