Sorry Arnold, I don't know what I was talking about below, one sentence I was talking about your rocking engine, the next I was saying to build one! Will blame it on being tired! :scratch: :doh: :wack: That's a good idea, it would make a great present! :thumbup: Nick |

Not much to report on this. Last night I did make the 2nd of 3 pedestals that support the frame. There wasn't any point taking pics as it was the same as the first one. everything went to plan except underestimated how long it would take again. Just under 2 hours in total, what a fiddley little thing it is! Oh well, only 1 more to do. If I can get in the garage at 8 instead of 10 tonight (had to watch a film to keep the wife happy last night) I should be able to make the final pedestal and I am hoping the bit of brown stuff for the base. Then tomorrow night I'll make a start on the Flywheel, that I am sure will need 2 nights - mainly because of the hand sawing!, but you never know, I might surprise myself! Even if I do finish that on sat night, I'll still need sun night to strip it down, clean / polish and reassemble with gaskets. So that's the plan, hopefully it will be a finished article by the end of this weekend. I will then update any drawings as necessary and publish on here incase anybody wants to have go ... :proj: Nick |

You have almost doomed it to failure Nick. Every time I try to guesstimate times like that, something goes pear shaped :lol: John |

Bogs you're probably right ... could be 2 months on and still no chuffing sounds! :doh: On my hot air engine project I had a long stall in the middle of it when it started getting difficult, but this time I'm nearly finished so it will take a lot more to stop me! I just need a few :poke: and :whip: and I should cross the finish line soon! You're right though, I shouldn't have tempted fate .. never learn! :bang: Nick |

Hi all, Tonight went pretty well .. in the end! I made a start on the base with some brown stuff. It creates funny swarf … faster to saw than that 2” steel bar though! Milling it square and to size The sizes I designed it only just fit in the milling vice with the jaws removed … just! Funny stuff this brown stuff Drilling the holes … in the wrong place ... grrrrr! The brown stuff must have known I was taking the mick and got its own back … bloomin awful stuff! Just before I chucked it at the wall I decided I could turn up a plug out of the small off cut of wood I kept .. knew it would come in handy! Turned it for a knock in fit. Putting the chamfer on with the countersink … this worked pretty well. Counterboring the underneath for the nuts to hold it down. The finished base, pretty happy with it. You can see the plug but I even turned it the right way to get the grain going same way! Actually, it’s a really nice bit of wood, machines really well! Didn’t split or anything once. I also managed to get the other pedestal done, and all pretty early too, by about 10:45! Trial fit of engine on base: Quite happy with it, looking quite good, or will do when it’s cleaned and polished! Just the flywheel to do … I even made a start on that .. Well, it’s a start! Looks like Sunday is still on for a running engine (fingers and toes crossed!) Nick |
