Looks good. |

I now have a flywheel with 6 decorative holes in it. Rotary Table is, er , well - um: not good Put a Centre into the Mill (had to take the Draw Bar out) Centred the table and bolted it down. Checked the runout on the edge - looks good to me..... Dropped the same centre into the flywheel. Bolted the flywheel through the centre hole, Checked the runout - 3rd time I got lucky ! Then you encounter the lash. About 1/4 turn of the handle each way. Centre drilled 6 places (60 deg apart), then 5mm and 13mm drill. (The largest I have) That all went well. The only thing I have 16mm is an end mill. That would have to make said 16mm holes. The lash coupled with a VERY poor clamp screw has confirmed which side is the outside ! Anyway, 6 X 16mm holes in the flywheel sorta 60 deg apart.... |

Fly wheel and cylinder looks good :thumbup: I drilled with four 22mm holes but it made my old drill sweat a bit, so drew it up with 6*16mm ish holes near enough is good enough for position I just marked mine out and went for it :D I know of three engines being made out there :whip: Stew |
| NickG:
Yeah nobody will be able to tell. I always mess them up the lightening holes! |

Hi Stew You have probably gathered that I'm not an experienced Engineer ! Finding Documented projects out there is always hard. The ME Article got me interested in this one, then your write up on here gave me the missing bits I need to get going. The Puddleduck I built was in reality beyond my ability. It was and was supposed to be a challenge. I knew that the chances of it working were slim. Saying that, John's Docs were easy to follow and gave me enough info to really learn how to do this stuff. Your Engine looks like I can both build it and it will work at the end of it all. Looking at your Youtube Ch I'm in awe of the stuff you have built. I looked at the Dake Engine but decided that would be beyond my ability. The Simpson engine is a work of art. Oh - and where do I get a Wobbler Bar (used to center the Piston Valve ). Does it have another name ? |
