| John Rudd:
Nice job, good to see something come of all your hard work... :bow: |

Thanks John. Lots more work to do. Ran it at Saturday's show, and after 1/4hr the whole crank assembly was wagging about, loose! :bang: The bearing column, isn't fixed on to anything substantial....... It's more of a "looking at", engine....... :scratch: |

Nice little engine - I enjoyed the photos and video. Thanks for taking the time and trouble to post them. John. |

Thanks John! I'm afraid, I don't agree with the "little", comment. To me, it's just, big. Very poorly designed, and built...... :hammer: (Just the sort of project I like)....... :thumbup: After a few weeks silence. I can only report, more negative progress, on this frustrating project....... :palm: After some 10mins running, at Earl Shilton. The crank assembly began rocking from side to side, on it's single, 6mm wide upright! Reminded me of stepping into a rowing boat/ dinghy........ Secured with M3 countersunk screws....... Up close. "You could stick yer cap neb, under there!"....... It's almost stood on tiptoe! The column base isn't flat! :bang: :bang: You can see the rub mark, of the "keel". Inboard of the outer two screw holes....... I'm now planning a new crankshaft assembly. With bearings at each end. As it should be....... :wink: Thanks for looking in! David. |

Yikes! It has been almost 9 months, since I last wrote anything about this, shambles! :Doh: As we can now, all, see the previous Pbucket pics, using the appropriate add ons....... Firefox..... https://addons.mozilla.org/en-US/firefox/addon/photobucket-fixer/ Chrome..... https://chrome.google.com/webstore/search/photobucket_hotlink_fix?hl=en I'll continue with, Blundering with Boris. Hope, there's still some interest! :scratch: I wondered, why the new displacer insisted on catching the inside of the hot cap. The shaft guide was at an angle, having been hammered into the bulkhead...... :bang: Time to strip, completely. And, totally rebuild...... I've taken the pics, as I've gone along. Not always, in sequence..... First job, was to get rid of the unnecessary/ leaking, water jacket. Four inch dia. Made from tough stainless steel. Not easy to machine, with a mini lathe's power..... What a mess, in there! I intended incorporating the end flange, into the cooling fins....... But. The darned thing fell off. After I'd drilled the new screw holes..... Yet another "interesting situation", needing a solution........ :palm: More to follow. Thanks for looking in. :thumbup: |
